Powersonic PS-1250-F2

Powersonic PS-1250-F2 Sealed Lead Acid Backup Battery

The Powersonic PS-1250-F2 is a compact 12-volt 5 Ah sealed lead acid (SLA) rechargeable battery providing reliable backup power for fire alarm control panels, wireless security sensors, emergency lighting fixtures, and life safety notification devices in small commercial facilities, apartments, retail locations, and residential properties. This ultra-compact, maintenance-free battery utilizes proven Absorbed Glass Mat (AGM) technology to deliver dependable emergency power in space-constrained installations where battery footprint is severely limited, making it the ideal solution for modern fire alarm systems requiring minimal cabinet space.

Compact Design & Physical Specifications: The PS-1250-F2 measures just 3.54 inches length by 2.76 inches width by 3.98 inches height, weighing only 3.06 pounds (1.39 kg), enabling installation in the smallest fire alarm control panel battery compartments and enclosure designs. The F2 terminal configuration provides fast-on connectors (0.250 inch spade terminals) compatible with standard fire alarm panel connectors and battery charging harnesses, ensuring straightforward integration into existing systems without requiring adapters or custom fabrication. Valve-regulated spill-proof construction allows safe mounting in any orientation, vertical or horizontal, without risk of electrolyte leakage or hazardous battery acid spillage.

Electrical Performance & Capacity: The PS-1250-F2 delivers 5.0 Ah nominal capacity at 20-hour discharge rate, storing 60 watt-hours of backup energy sufficient for 8-24 hours of continuous control panel operation during extended power loss events. The battery features maximum discharge current capability of 50 amperes for short-duration peak-demand scenarios, with internal resistance of just 48 milliohms enabling rapid discharge cycles. Gas recombination technology facilitates fast recharge from standard 14.1-14.7 volt (2.35-2.45 volts per cell) charging supplies with initial charging current limited to 1.5 amperes, enabling quick recovery between charge/discharge cycles without overheating or thermal runaway.

Environmental Ratings & Industry Certifications: The PS-1250-F2 operates reliably across -20°F to 140°F discharge temperature ranges, with recommended operation in 5°F to 104°F ambient conditions typical of climate-controlled facilities and outdoor equipment enclosures. This battery carries full UL 1989, CE, ISO 9001:2015, IEC 60896, RoHS, REACH, and VdS certifications, meeting all regulatory standards for emergency backup power in fire alarm and life safety systems throughout North America, Europe, and international markets. A 2.5-year Powersonic warranty ensures long-term reliability and manufacturer support for critical backup power applications.
