Industrial rectifiers and battery chargers are critical power supply systems used in HV (High Voltage), MV (Medium Voltage), and LV (Low Voltage) energy control and automation applications.
They ensure uninterrupted DC power for essential functions such as:
• Protection relay control
• Circuit breaker operation
• Communication systems
• Automation and control circuits
• Emergency lighting during power outages
These systems are designed to operate with battery support, guaranteeing reliable DC power even when the AC grid fails.

How Do Industrial Rectifiers Work?

Industrial rectifiers convert single-phase or three-phase AC mains power into stable DC power suitable for industrial applications.
First, the incoming AC voltage is reduced to the required level using a step-down transformer, which also provides galvanic isolation to ensure safety and system reliability. The rectifier circuit—typically based on thyristor or semiconductor technology—then converts AC power into DC power.
The generated DC output is filtered to eliminate ripples, resulting in smooth, clean, and stable DC energy.
Using advanced rectifier control software, this DC power:
• Supplies continuous energy to DC loads
• Charges batteries according to float, boost, and equalize charging modes

Operation During Power Failures

In the event of an AC grid failure, the rectifier system automatically switches to battery operation, ensuring uninterrupted power supply to all connected DC loads.
The batteries continue to support the system for a pre-calculated backup duration (such as 4, 6, 8, or 12 hours), based on the programmed discharge parameters.
Once grid power is restored, the rectifier seamlessly resumes operation and recharges the batteries automatically.

UPS systems used in boiler rooms activate immediately when the power goes out, ensuring that the boiler control board, circulation pump, and other control components continue to operate. This eliminates safety risks and prevents the system from shutting down. Especially in areas where power outages are frequent, boilers operating without UPS have high failure rates. This situation leads to costly repairs and disruptions to user comfort.

Why is it essential to use a UPS for a boiler?

Although boiler systems have a mechanical structure, they require electronic components to continue operating. The control panel, ignition system, pump motors, and sensors are powered by electricity. When the power goes out, these components stop working and the following problems arise:

• The boiler suddenly stops and the water circulation is interrupted.
• Due to the rise in temperature, the water in the boiler may approach boiling point.
• Pump motors may be damaged.
• There is a risk of the electronic card burning out.
• During a winter outage, the building is left completely without heating.

All such problems can be easily prevented with a UPS of the correct capacity. When a UPS is used, even if there is a power outage, the system does not shut down completely; the pumps continue to operate and ensure that water circulates within the boiler. This is an essential requirement for both comfort and safety.

Which UPS Type Should Be Used in a Boiler?

Since boiler systems contain motorized equipment, the UPS used must be suitable for this purpose. Therefore, the most appropriate choice is an online UPS model.

One of the most frequently asked questions when purchasing a boiler UPS is the correct power capacity. This is because boiler systems use both electronic cards and one or more circulation pumps. Pump motors draw high current during initial startup. Therefore, a UPS with a capacity greater than the actual load should be selected.

The general calculation is as follows:

• Boiler control board: 20W – 80W
• Circulation pump: 60W – 120W (varies by model)
• Second pump (if applicable): +60W – 120W

An example system:

• Boiler card → 40W
• 2 pumps → 2 × 90W = 180W

Total load: 220W

Ideal UPS power range for this type of system:

• 2 kVA Online UPS
• 3 kVA Online UPS (recommended for high-security systems)

In larger boiler rooms or commercial buildings where multiple pumps are used:

UPS (Uninterruptible Power Supply) kicks in the moment the power goes out, ensuring the elevator safely moves to the nearest floor and the doors open. It also regulates power fluctuations, preventing damage to the electronic control panel. Elevators have high-power motors, so the UPS used must be more powerful, more stable, and compatible with the motor load than standard UPS models.

Why is a UPS Necessary for Elevators?

An elevator suddenly stopping during a power outage is a panic-inducing and dangerous situation for those inside. Power outages in elevators without UPS systems pose the following risks:

• Passengers being trapped inside the cabin
• Failure to conduct an emergency evacuation
• Mechanical stress occurring in the cabin and engine group
• Damage to the elevator control board due to fluctuations
• Operational disruption in heavily used buildings

The UPS system eliminates all these risks. When the power goes out, the elevator moves to the most appropriate floor based on its operating speed, and the doors open automatically. This allows passengers to be safely evacuated.

How Does an Elevator UPS Work?

The elevator UPS regulates the electricity it receives from the grid under normal conditions and transmits it to the control system. It also charges its batteries. When the power goes out, it kicks in and provides the necessary energy to the motor driver. This allows the elevator to continue operating in safe mode without sudden stops.

The operating principle of UPS is as follows:

• When connected to the grid: Filters energy and charges the batteries.
• During a power outage: Switches to UPS mode within milliseconds.
• Directs the elevator to the safe floor: The motor slowly moves to that floor.
• Enables doors to open: Creates a safe environment for evacuation.

This seamless transition is essential to prevent injury to passengers and to protect elevator equipment.

Why Should Online UPS Be Used When Selecting an Elevator UPS?

How Does the Efficiency Certificate Affect Price?

The efficiency of a PSU determines how much of the electricity it receives it can transfer to the computer. 80+ Bronze and 80+ Gold PSUs are preferred because they provide both stable operation and low heat generation. As efficiency increases, the PSU experiences less energy loss, generates less heat, and operates more quietly. This translates to a longer lifespan and higher performance. Therefore, the efficiency certification directly impacts the price of the power supply.

Things to Consider When Choosing a Power Supply

Since there are many PSU models on the market, users should pay attention to certain technical criteria when making their selection. Choosing a PSU based solely on wattage is a big mistake. The most important factors to consider are as follows:

• True wattage support: Some PSUs specify nominal wattage, but their actual output power is lower.
• Safety circuits: Without protections such as OVP, OCP, and SCP, the risk of PSU failure increases.
• 12V channel power: Since modern graphics cards are powered by the 12V line, it is important that this line is powerful.
• Cable structure: Modular PSUs reduce cable clutter.
• Fan quality: Quiet and durable fans extend the PSU’s lifespan.

These criteria help you establish the right relationship between PSU price and quality. It is possible to choose an affordable PSU, but you should avoid very cheap devices in terms of safety and performance.

Use of UPS in Computer Systems

When researching computer power supply prices, most users also seek answers to the question, “How can I protect my system?” This is where UPS usage comes into play. Desktop computers, in particular, are highly susceptible to power surges and sudden outages.

Why Do Pharmacies Have to Use UPS?

When we consider the daily workflow of a pharmacy, it becomes clear just how critical electrical power is. Even a brief outage can cause systems to shut down, interrupt operations, and in some cases, lead to data loss. The main reasons why UPS is essential for pharmacies are as follows:

• Preventing the Automation System from Shutting Down: Prescription entries, drug sales, inventory tracking, and reporting are performed through the pharmacy automation program. If the computer and system suddenly shut down during a power outage, ongoing processes will be interrupted and data integrity may be compromised.
• Protecting Cold Chain Products: Vaccines, certain antibiotics, and heat-sensitive drugs are stored in medicine cabinets or refrigerator systems. In the event of a power outage, the cabinet stops working, and prolonged outages pose a risk of spoilage for the drugs.
• Maintaining Uninterrupted Customer Service: When the POS device, barcode scanner, and printer are not working, sales transactions cannot be completed. This situation both reduces customer satisfaction and causes serious queues during busy hours.
• Ensuring Data and Device Security: Sudden power outages and voltage fluctuations can damage the electronic components of devices such as computers, modems, cash registers, and printers. A UPS filters out these fluctuations, extending the life of your devices.
• Preventing Business Loss: Especially in pharmacies located in central areas, even a brief interruption can result in significant revenue loss. With UPS, the system remains operational, minimizing this loss.

The Most Suitable UPS Type for Pharmacies: Why Online UPS?

Although there are different types of UPS available on the market, the safest and most professional solution for pharmacies is online UPS models. Standby or line-interactive UPSs may be considered for simpler systems; however, due to the sensitivity and critical role of the devices used in pharmacies, the online structure provides higher security.

The main advantages that Online UPS offers for pharmacies are as follows:

• Continuous and Clean Energy: Online UPS converts the energy it receives from the grid first to DC, then back to AC. This ensures that the energy supplied to the system is always at a constant voltage and frequency. Sudden surges or drops in the grid do not affect the system.
• Near-Zero Transfer Time: While conventional UPS systems have a very short transfer time when the power goes out, online UPS systems have a transfer time that is virtually zero. Devices such as pharmacy automation systems, computers, and modems continue to operate without experiencing any interruption.
• Structure Suitable for Sensitive Electronics: Computers, POS devices, printers, and network equipment are highly sensitive to sudden voltage changes. Online UPS ensures the safe operation of these devices.
• Advantage for Refrigerators: If a medicine cabinet or small refrigerator is also to be connected to the UPS, the online UPS offers a significant advantage because it supplies motorized loads more stably.

How to Determine the Appropriate UPS Capacity (kVA) for Pharmacies?

One of the most confusing issues when choosing a UPS for pharmacies is finding the right power capacity. The goal here is not only to run existing devices, but also to leave a little room for possible additional devices or future expansions. The following steps can be followed when determining capacity:

1. List the Devices to be Connected to the UPS: Note all devices such as computer(s), monitor(s), cash register, POS device, printer, modem, switch, barcode reader, medicine cabinet.
2. Find Out the Wattage of Each Device: The power consumption information is listed on the power labels or technical documentation of the devices. Add up these values.
3. Calculate Total Consumption: For example, 1 computer + monitor consumes 150–200W, modem and network devices consume 20–30W, printer consumes 50–70W, and POS and barcode systems consume around 30–40W.
4. Add a Safety Margin: Adding a safety margin of 20–30% to the total wattage ensures the UPS operates smoothly.
5. Convert to kVA Value: As a practical calculation, it can be assumed that 1 kVA can safely carry a load of approximately 700–800W.

In general, the following capacity ranges are suitable for pharmacies:

• Small pharmacies: For a single computer, POS, modem, and printer, a 1 kVA – 2 kVA online UPS is usually sufficient.
• Medium-sized pharmacies: For pharmacies with multiple computers, printers, multiple POS devices, and network equipment, a 2 kVA – 3 kVA Online UPS may be preferred.
• If a refrigerator or vaccine refrigerator is also to be connected: In this case, based on the full load calculation, an Online UPS rated at 3 kVA or higher is a safer choice in most scenarios.

The Role of UPS and RedSan Store for Pharmacies

Choosing the right UPS model can be challenging, especially for pharmacy owners who are not familiar with the technical details. It may not always be clear which kVA rating is sufficient, which devices need to be connected to the UPS, or what the practical differences are between online UPS and other types. At this point, RedSan Store, which offers UPS models with appropriate capacity and features for pharmacies, can provide significant support in terms of both products and technical consulting.

You can get technical support from RedSan Store to determine which UPS capacity you need based on the size of your pharmacy, the number of devices, and usage intensity. You can choose the most suitable model for your business from the online UPS models ranging from 1 kVA, 2 kVA, or 3 kVA. This way, instead of buying a random product, you will have invested in a professional solution that truly meets your needs.

Which Devices Should Be Connected to the UPS, and Which Should Not?

When using a UPS in pharmacies, it is important to correctly determine which devices should be powered by the UPS. Connecting every device to the UPS may not always be necessary or logical. For example, some high-power lighting systems or devices that create unnecessary load can unnecessarily fill the UPS outputs.

The general approach should be as follows:

• Devices that should be connected to a UPS: Pharmacy automation computer, monitor, POS device, modem/router, switch, printer, barcode reader, cash register, and critical communication/processing equipment.
• Devices that can be connected to the UPS depending on the situation: Medicine cabinets, vaccine or refrigerated cabinets, small-scale air conditioning or ventilation systems (depending on battery life and UPS capacity).
• Devices that are generally not recommended to be connected to a UPS: High-power electric heaters, decorative lighting, and non-critical devices that unnecessarily consume the UPS’s capacity.

The goal here is to use the battery time provided by the UPS as efficiently as possible and, in the event of an outage, to keep the devices that are “essential for the pharmacy to operate” running first.

Common Mistakes in UPS Usage

Although the use of UPS in pharmacies is becoming increasingly common, some common mistakes can prevent the investment from yielding its full potential. Being aware of these mistakes is important for establishing correct usage.

• Selecting an undersized UPS: Continuing to use the initial small UPS despite an increasing number of devices will lead to the UPS frequently sounding alarms, becoming overloaded, and failing to provide sufficient runtime during outages in the future.
• Neglecting battery maintenance: UPS batteries lose capacity over time. If regular testing and battery replacement when necessary are not performed, the UPS may run out of power quickly even if it activates during a critical moment.
• Overloading UPS outlets: Connecting additional devices based on the logic of “there’s an empty outlet, I’ll plug it in” without technical calculation can disrupt the UPS’s balance.
• Neglecting grounding and infrastructure: A UPS provides maximum protection when used with a good electrical infrastructure and proper grounding.
• Improper installation: Random connections, incorrect phase, or faulty outlet usage may prevent the UPS from providing protection.

A Strategic Approach to Planning UPS Investment

When purchasing UPS systems for pharmacies, it is best to view this investment not merely as a short-term “expense,” but rather as a strategic step in terms of business continuity, data security, and equipment health. In areas with problematic electrical infrastructure or frequent power outages, this investment can pay for itself in a very short time. For example, the cost of medications that could spoil during a single serious outage often exceeds the price of a UPS.

Therefore, when choosing a UPS:

• Review the frequency and duration of past interruptions.
• Determine your capacity by considering your pharmacy’s growth potential.
• Choose an online UPS for maximum protection against power fluctuations.
• Work with a supplier that offers technical support, such as RedSan Store, to get professional advice on kVA selection.

With the right UPS selection and proper installation, your pharmacy can operate seamlessly and safely both during daily operations and unexpected power outages. This not only enhances customer satisfaction but also protects your equipment and inventory.

A UPS is a power source that kicks in the moment the power goes out, keeping the refrigerator running and preventing the food inside from spoiling. It also filters out voltage fluctuations, preventing damage to the refrigerator motor. With a UPS of the right capacity, it is possible to protect the refrigerator, providing significant advantages in terms of both safety and cost in the long run.

Why is a UPS Necessary for a Refrigerator?

While a refrigerator stopping during a power outage is risky even for home users, this risk is much greater for businesses. Refrigerators store critical products in markets, cafes, restaurants, pharmacies, and even some laboratories. The spoilage of these products can lead to serious health consequences in addition to financial losses.

Using a UPS for your refrigerator is important for the following reasons:

• Elektrik kesintisinde gıdaların bozulmasını önler: İç sıcaklık kısa sürede yükselir, bu UPS sayesinde geciktirilir.
• Ensures the cold chain is maintained: This is particularly critical for dairy products, meat products, medicines, and vaccines.
• Prevents voltage fluctuations from damaging the motor: Motor windings can be affected by fluctuations very quickly.
• Extends the life of your refrigerator: A motor that runs on clean and stable energy will operate without failure for a longer period of time.
• Prevents sudden power outages from damaging the compressor: When the motor starts and stops, there is a risk of serious damage, and the UPS reduces this risk.

Frequent power outages, especially during the summer months, make refrigerator use more risky, while a UPS device minimizes all these risks.

What is the Most Suitable UPS Type for a Refrigerator?

Refrigerators are motorized devices and therefore draw high starting currents. For this reason, the UPS to be used for the refrigerator must be compatible with the motor load. The most suitable type to ensure this compatibility is Online UPS models.

The main reasons why an online UPS is suitable for a refrigerator:

• Near-zero transition time: The refrigerator does not stop or experience sudden shocks when the power goes out.
• Can handle the inrush current: The refrigerator motor draws high watts when it first starts; the online UPS supports this current.
• Provides full protection against voltage: Fluctuations or sudden surges do not affect the motor.
• Provides stable energy: The refrigerator operates more quietly and lasts longer.

Standby or line-interactive UPS models are often insufficient for motorized devices. Therefore, an online UPS is the most appropriate choice for refrigerators.

What UPS Capacity in kVA is Suitable for a Refrigerator?

The power requirement of a refrigerator varies depending on the model, but generally consumes between 100W and 250W of energy. However, the critical point is the high current drawn by the motor when it first starts up. The starting current can be up to 2–3 times the normal operating consumption.

For this reason, when selecting the appropriate UPS capacity for a refrigerator, it is necessary to pay attention not only to the operating wattage but also to the starting power.

General recommendations:

• For household refrigerators: 1 kVA – 2 kVA Online UPS
• For medium-sized commercial refrigerators: 2 kVA – 3 kVA Online UPS
• For large commercial refrigerators/beverage coolers: 3 kVA – 6 kVA Online UPS

If the refrigerator runs frequently or is used in hot regions, it is safer to choose a UPS with a slightly higher capacity.

The Benefits of Using a UPS for Your Refrigerator

A UPS not only keeps the refrigerator running during power outages; it also improves motor health and energy efficiency.

Key advantages:

• Protects the engine: Reduces the risk of engine damage during fluctuations.
• Reduces refrigerator noise: Stable electricity ensures quiet operation.

What Other Devices Can Be Connected to the UPS Besides a Refrigerator?

When connecting a UPS to a refrigerator, most users wonder, “Is it okay to connect other devices?” This depends entirely on the UPS capacity and the refrigerator’s power consumption.

The general principle is as follows:

• Critical devices take priority: If the refrigerator is to be connected to the UPS, the load on the UPS should not be filled with unnecessary devices.
• Small devices can be added: Modems, internet routers, small lights, or cash register systems can be added; however, they must not exceed the UPS wattage rating.
• High-power devices should not be connected: Devices such as electric heaters, air conditioners, and kettles should never be operated through the UPS.

Here, UPS’s protection function should primarily focus on the refrigerator.

Here, the UPS’s protective function should primarily focus on the refrigerator.

Using a UPS for a refrigerator is quite safe; however, certain points require attention:

• Selecting the correct capacity is essential. An insufficient kVA UPS may not be able to run the refrigerator.
• Battery life should be planned according to expectations. The higher the battery capacity, the longer the interruption time.
• A fixed outlet and proper grounding must be used.
• The UPS should be kept away from heat sources.
• UPS and battery tests should be performed at regular intervals.

These steps ensure the long-term operation of the UPS and protect the refrigerator in the best possible way.

What Are the Long-Term Benefits of Investing in a UPS for Your Refrigerator?

Many users view UPS investment as an unnecessary expense; however, when considering the long-term benefits it provides, it is actually a significant saving. The cost of food that could spoil during a single power outage can often exceed the entire price of a UPS. Similarly, the repair or replacement cost of a refrigerator experiencing motor failure is quite high.

UPS provides the user with the following long-term benefits:vv

• Prevents economic losses
• Protects the refrigerator motor
• There is no stress during power outages
• Energy efficiency increases
• Device lifespan increases

For these reasons, a UPS is one of the most reliable investments you can make for critical appliances such as refrigerators. It ensures that food and cold chain products are stored safely without being affected by power outages. With the right UPS model, your refrigerator will operate with full protection against both outages and voltage fluctuations.

What is Deep Discharge of a Battery?

Deep discharge occurs when more than 80% of the battery’s capacity is used or when the battery’s nominal voltage drops below its safe operating values. For example, the safe limit for a 12V battery is around 11.8V. Dropping below this voltage initiates chemical deterioration in the cell structure. Deep discharge can cause irreversible damage, particularly in gel and AGM batteries. In lithium batteries, deep discharge can cause the cells to shut down completely.

Deep discharge in battery systems usually occurs due to high energy demand, insufficient capacity selection, or prolonged lack of charging. The more frequently it occurs, the shorter the overall life of the battery.

The Effect of Deep Discharge on Battery Chemistry

Batteries store chemical energy thanks to their electrolyte and plate structure. When deep discharge occurs, the structure of the plates begins to deteriorate, and sulfate crystals concentrate, especially in the lead-acid group. This alters the acid balance of the electrolyte and reduces battery capacity.

When sulfation becomes permanent, the battery cannot deliver the desired current and voltage even when fully charged. In other words, the battery appears to be full, but its functional capacity is significantly reduced. This chemical change is irreversible and shortens the battery’s life.

Why Does a Deeply Discharged Battery Lose Capacity?

During deep discharge, the active material structures inside the battery are damaged, causing the chemical reactions within the battery to become inefficient. This leads to a decrease in capacity. The more a battery is subjected to deep discharge, the faster its working capacity decreases.

Capacity loss manifests itself as follows:

• The battery drains faster.
• It stores less energy after charging.
• Charging time increases.
• The battery experiences a faster voltage drop under load.

The Relationship Between Battery Cycle Life and Depth of Discharge

Every battery has a cycle life. Cycle life refers to how many times a battery can withstand a full charge to a full discharge. As deep discharge increases, the number of cycles decreases. For example, deep-cycle gel batteries offer 1200 cycles at a 50% discharge level, while at an 80% discharge level, this value can drop to 600 cycles.

Therefore, always using the battery within the 50–70% capacity range significantly extends its life.

AGM, Gel, and Lithium Batteries: Differences in Deep Discharge

AGM Batteries: They are more sensitive to deep discharge, and their capacity decreases rapidly under frequent deep discharge conditions.

Gel Batteries: They have higher deep cycle performance and tolerate up to 70% discharge better. For this reason, they are common in solar and mobile systems.

Lithium Batteries: Thanks to the BMS (Battery Management System), they protect the cells and automatically shut down when deeply discharged. However, lithium cells that remain closed for a long time can become irreversibly damaged. They are common in mobile systems.

Common Reasons for Deep Discharge in Solar Systems

• Insufficient selection of solar panel capacity
• Low battery capacity
• Incorrect calculation of load consumption
• Incorrect charger regulator settings
• Short daylight hours during winter months

Installing solar systems without calculating battery capacity is the most common cause of deep discharge.

Battery Life-Shortening Incorrect Charging and Discharging Habits

• Do not charge the battery to full capacity
• Discharging the battery completely frequently
• Using the wrong charging voltage
• High-current discharge

These significantly reduce both the battery’s cycle life and efficiency.

Overload, Thin Wiring, and Loss Problems

System wiring plays a decisive role in battery efficiency. Thin-gauge cables heat up when carrying load current and cause power loss. This leads to the battery consuming more energy unnecessarily and discharging more quickly.

The cable cross-section must always be selected correctly according to the load current.

The Effect of Battery Charging Control Device Selection on Deep Discharge

The charge controller is a critical component that prevents the battery from over-discharging. MPPT regulators charge the battery more efficiently and stably, providing higher efficiency compared to PWM regulators. Additionally, most MPPT devices feature a deep discharge protection setting.

Failure to make this adjustment correctly may cause the battery to deteriorate quickly.

Practical Solutions to Prevent Deep Discharge

• Calculate the battery capacity accurately according to the actual need.
• Configure the charger regulator settings according to the battery type.
• Be sure to choose models with a BMS in lithium batteries.
• If necessary, add an additional solar panel or a second battery to the system.
• Connect high-current devices to a separate circuit.

These simple measures both improve battery performance and reduce long-term costs.

The Function and Operating Principle of the UPS Battery

UPS bataryalarının temel görevi, elektrik kesildiğinde sisteme geçici bir süre alternatif güç sağlayarak cihazların kapanmadan çalışmasını sürdürmesini sağlamaktır. Bu süre, UPS’in güç kapasitesine ve bataryanın sağlığına bağlı olarak değişir. Batarya, şebeke elektriği mevcutken sürekli olarak şarj edilir; kesinti gerçekleştiğinde ise depoladığı enerjiyi devreye alır.

VRLA (Valve Regulated Lead Acid), AGM, or Gel batteries are most commonly used in UPS systems. These batteries are maintenance-free, leak-proof, and suitable for enclosed environments. However, like all batteries, they experience performance loss over time, which directly affects the UPS’s power support. Therefore, the condition of the battery is the biggest determinant of the UPS’s reliability.

Factors Affecting UPS Battery Life and the UPS Battery Replacement Process

The lifespan of UPS batteries is not determined solely by production quality; usage conditions, charge-discharge cycles, and environmental conditions also play a major role. The main factors affecting battery life are as follows:

• Ambient Temperature: 20–25°C is the ideal temperature range. Higher temperatures can reduce battery life by up to 50%.
• Charge and Discharge Cycles: Frequent and deep discharges reduce the chemical stability of the battery.
• UPS load level: If the UPS continuously operates near maximum capacity, the battery will wear out faster.
• Frequency of use: Battery wear occurs more quickly in areas with frequent power outages.
• Battery quality and brand: Low-quality batteries may lose capacity within a short period of time.

All these variables significantly determine the actual service life of the battery.

How Long Does the Battery Last? Average Usage Times

The average lifespan of UPS batteries typically ranges from 2 to 5 years. However, the actual lifespan may be shorter or longer depending on usage conditions. A high-quality AGM or gel UPS battery used under ideal conditions can last up to 4–6 years, while batteries operating in high temperatures and under heavy loads may have a lifespan as short as 1–2 years.

Regular monitoring of battery life is particularly critical in data centers, medical device rooms, automation systems, and critical infrastructure.

How to Recognize a Performance Decline in a UPS Battery?

UPS batteries typically wear out slowly and may not be noticeable at first glance. However, some obvious signs indicate that it is time to replace the battery:

• UPS provides power for a shorter period of time.
• UPS batarya uyarı ışığı veya alarm sesi verir.
• UPS test modunda ani kapanma yaşanır.
• The battery swells when it comes into contact with the eye.
• The device is running hotter than normal.

If any of these symptoms are observed, the condition of the battery must be checked.

Symptoms of Not Holding a Charge, Overheating, and Capacity Loss

In some cases, the battery may appear physically intact but have lost its capacity. In this case:

• Even though the UPS shows it is charging, it shuts down quickly during an outage.
• The battery overheats while charging.
• The UPS takes longer than usual to charge.
• Even with short-term loads, battery voltage drop occurs.

These symptoms indicate that the battery’s internal chemical structure is no longer functioning stably and that replacement is necessary.

UPS Battery Replacement: UPS Test Mode and Periodic Inspection Methods

Most UPS devices have a test mode. This test measures how long the UPS can operate in an emergency. This test should be performed at regular intervals (every 3 months). Additionally, by professional maintenance teams:

• Battery voltage and internal resistance measurement
• Charge stability control
• Temperature sensor test
• Load simulation test

it is recommended to do so.

The Effect of UPS Ambient Temperature and Ventilation

The biggest enemy of UPS batteries is high temperatures. When the ambient temperature increases by 10°C, battery life can be reduced by half. The room where the UPS and batteries are located must be well ventilated and not exposed to direct sunlight or hot air.

Ideal temperature: 20–25°C
Ideal location: Dry, ventilated indoor area

When is UPS Battery Replacement Absolutely Necessary?

The battery must be replaced in the following situations:

• If the battery is swollen, deformed, or leaking
• If the device shuts down in UPS test mode
• Batarya 4 yıldan daha uzun süredir kullanılıyorsa
• If the UPS is giving an alarm or error warning
• If the capacity loss has decreased significantly

Original and Compatible Battery Selection Criteria

Each UPS model works optimally with specific battery technologies. Therefore, the following criteria must be considered when replacing batteries:

• Brand and model compatibility
• Voltage and ampere-hour (Ah) value matching
• Battery type (AGM, gel, etc.) compatibility
• Choosing a quality and reliable brand

Cheap, low-quality batteries can fail quickly, causing both financial loss and system risk.

Safety and Installation Considerations for UPS Battery Replacement

When replacing the battery:

• The device must be completely turned off and unplugged.
• The pole heads must be removed and installed in the correct order.
• Kablo uçlarında kıvılcım oluşumunu önlemek için metal temas engellenmelidir.
• Eğer sistem büyükse değişim mutlaka uzman ekip tarafından yapılmalıdır.

Incorrect installation may damage the UPS and connected devices.

What is a Gel Battery?

Jel akülerde elektrolit sıvısı, jel kıvamına getirilmiş silika bazlı bir madde içerisinde sabitlenmiştir. Bu jel yapı, akü içerisinde elektrolitin akışını ortadan kaldırır ve plakalar ile elektrolit arasındaki temasın dengeli olmasını sağlar. Böylece jel aküler yüksek sıcaklıklara ve titreşime karşı daha dayanıklı hale gelir. Gaz çıkışı neredeyse sıfıra yakın olduğu için kapalı alan kullanımına son derece uygundur.

Gel batteries provide high efficiency in solar systems, caravans, marine systems, and uninterruptible power supplies where there is a need for long-term energy at low currents. Performance stability during long deep discharge cycles is one of their most important advantages. However, gel batteries generally have longer charging times than AGM batteries because they allow for lower charging currents.

What is an AGM Battery?

In AGM (Absorbent Glass Mat) batteries, the electrolyte is held within a glass fiber mat. This design ensures the electrolyte is evenly distributed between the plates and contributes to low internal resistance. Low internal resistance means the battery performs better in applications requiring high current draw.

AGM batteries operate more efficiently in generator-backed systems, UPS systems, automotive start-stop systems, security systems, and environments requiring sudden high currents. Additionally, AGM batteries have a shorter charging time compared to gel batteries and tolerate fast charging better. However, their temperature sensitivity is higher than that of gel batteries.

Structural Differences Between Gel and AGM Batteries

Both battery types belong to the VRLA (Valve Regulated Lead Acid) class and are maintenance-free. However, structural differences directly affect performance:

• Gel battery: The electrolyte is in gel form → provides greater stability and longer cycle life.
• AGM battery: Electrolyte is contained in glass fiber → offers lower internal resistance and high current performance.

Bu fark, jel aküleri enerji devamlılığı gerektiren uygulamalarda; AGM aküleri ise yüksek akım ve hızlı şarj gerektiren uygulamalarda öne çıkarır.

Charging and Discharging Characteristics Comparison

Gel batteries require a more sensitive charging profile. An increase in charging voltage can cause damage to the gel structure. Therefore, gel batteries must be charged using chargers that support gel mode.

AGM batteries are more tolerant to charging and support fast charging. However, incorrect charging settings can also cause long-term capacity loss in AGM batteries. AGM batteries manage high current discharges better, making them ideal for systems with sudden power demands.

Cycle Life and Durability Periods

Döngü ömrü, akünün tam şarjdan tam deşarja kaç kez dayanabileceğini ifade eder. Jel aküler genellikle AGM akülere göre daha yüksek döngü ömrüne sahiptir. Örneğin iyi bir jel akü 700–1200 döngü sunarken, AGM aküler 300–700 döngü aralığında performans gösterir.

Therefore, in systems with long-term and stable energy requirements, choosing gel batteries can be more economical in the long run.

Deep Discharge Performance and Capacity Preservation

Jel aküler derin döngülü kullanımda kapasite kaybını çok daha kontrollü şekilde yaşar. %50–80 deşarj seviyelerinde bile yapısal stabilite korunur. Bu nedenle güneş enerjisi sistemlerinde jel aküler uzun vadeli güvenilirlik sağlar.

AGM batteries are more sensitive to deep discharge. Capacity loss can accelerate when deep discharge is repeated frequently. However, AGM batteries perform better in applications requiring short-term high current.

Sıcaklık ve Çevresel Koşullara Dayanıklılık

Jel akü, iç yapısındaki jel sabitleyici sayesinde sıcaklık değişimlerine ve titreşime karşı daha dayanıklıdır. Bu nedenle karavan, tekne, marin sistemleri ve güneş enerjisi istasyonları gibi çevresel faktörlerin yoğun olduğu ortamlarda tercih edilir.

AGM batteries are more sensitive to temperature changes. They perform best in enclosed spaces, UPS rooms, and environments with stable temperature control.

Maintenance Requirements and Ease of Use

Both gel and AGM batteries are maintenance-free and do not require fluid refilling. However, gel batteries have a lower failure rate due to their more stable chemical composition.

AGM batteries are recommended for systems that undergo frequent charge-discharge cycles, so regular monitoring of temperature and capacity is advised.
