Red Battery 12 v 26 ah

Red Battery 12V 26Ah Maintenance-Free Dry Battery

Red Battery 12V 26Ah battery is a maintenance-free dry-type battery featuring VRLA (Valve Regulated Lead Acid) technology, developed for applications requiring high capacity. Offering a nominal voltage of 12 volts and a capacity of 26Ah, this model is a reliable power source for UPS systems, solar energy systems, security infrastructures, telecommunications equipment, and industrial power solutions.

Thanks to its low internal resistance (approximately 12 mΩ), it responds quickly to instantaneous loads requiring high current. It delivers powerful performance with a maximum discharge capacity of up to 360A (5 seconds). Its robust body construction and leak-proof design ensure safe and long-lasting use.
