Powersonic PS12750

Powersonic PS12750 Sealed Lead Acid Battery

The Powersonic PS12750 is a professional-grade 12-volt 75 Ah sealed lead acid (SLA) battery engineered for reliable emergency backup power in critical fire alarm, life safety, and security system applications. This rugged, maintenance-free battery delivers consistent power for backup lighting, control panel operation, and emergency notification systems across commercial facilities, healthcare institutions, educational campuses, and industrial environments where reliable uninterruptible power supply is non-negotiable.

Electrical Specifications & Performance: The PS12750 utilizes advanced Absorbed Glass Mat (AGM) technology providing 75 Ah nominal capacity at the 20-hour discharge rate, storing 960 watt-hours of backup energy with an internal resistance of just 7.2 milliohms. The battery delivers maximum continuous discharge capability of 750 amperes for peak-demand scenarios, with short-circuit capability reaching 1,725 amperes and initial charging current of 24 amperes. These robust electrical characteristics ensure rapid response during emergency power demands and accelerated recharge cycles between discharge events, critical for fire alarm systems requiring guaranteed backup power reliability.

Physical Design & Installation: Compact physical dimensions measure 10.25 inches length, 6.6 inches width, and 8.98 inches height, with terminal height of 8.43 inches, allowing flexible mounting in tight equipment enclosures and battery cabinets. The rugged impact-resistant ABS case weighs just 50.6 pounds (22.95 kg), with integrated carrying handles facilitating installation in vertical or horizontal orientation. Valve-regulated spill-proof construction enables safe operation in any position, eliminating hazardous battery acid spillage concerns typical of flooded lead-acid batteries.

Environmental Ratings & Certifications: The PS12750 operates reliably across expanded temperature ranges from -40°F to 140°F discharge temperatures, with optimal performance in 5°F to 104°F ambient conditions. This battery carries full DOT, IATA, FAA, and CAB approval for safe air transport, plus UL 1989, IEC 60896, ISO 9001:2015, CE, VdS, RoHS, REACH, and PFAS-free certifications, meeting all major regulatory standards for emergency backup power in fire alarm and life safety applications.
