LOCAL PICKUP ONLY

The Power-Sonic PS-12750 U 12V 75Ah SLA AGM Battery provides dependable rechargeable power for general-purpose, standby, and light cyclic applications. It combines sealed lead-acid construction with Absorbent Glass Mat technology for reliable and maintenance-free operation. In addition, its high capacity makes it suitable for fire and security systems, UPS equipment, emergency lighting, telecommunications, and other backup power applications.

Reliable 12V High-Capacity Power

The Power-Sonic PS-12750 U provides a nominal voltage of 12 volts. Its rated capacity reaches 80Ah at the 20-hour rate and 75Ah at the 10-hour rate. Therefore, it offers substantial energy storage for equipment that requires extended standby power.

The battery belongs to the Power-Sonic General Purpose SLA Series. This series supports float and light cyclic applications. As a result, the battery works well in systems that remain on standby and provide power when the primary source becomes unavailable.

Sealed AGM Technology

Absorbent Glass Mat technology holds the electrolyte inside the battery. Therefore, users do not need to add water or perform routine electrolyte maintenance.

The valve-regulated design also provides spill-proof operation under normal conditions. Moreover, gas recombination technology helps support efficient charging and dependable battery performance.

Universal Nut-and-Bolt Terminals

The U version features universal heavy-duty posts with nut-and-bolt fasteners. This terminal configuration provides a secure electrical connection for compatible equipment.

Power-Sonic specifies a terminal torque range of 11.0 to 14.7 N·m for the U terminal configuration. However, installers should always follow the equipment and battery installation requirements when making electrical connections.
