CSB HR 1251W F2 (12V 12Ah) UPS Battery

The CSB HR 1251W is a high-rate 12V 51W/cell VRLA AGM battery designed for high-performance UPS systems and high-power rapid discharge applications. It is deployed in industrial UPS units, telecommunications systems, and critical IT infrastructures where delivering high currents — up to 180A — over short periods and reliable performance during power failure are the essential standby power system requirements.

The rated capacity of 51W per cell at the 15-minute discharge rate places the HR 1251W firmly in the high-rate category, delivering superior performance compared to standard VRLA batteries in UPS applications with significant power peaks at switchover. AGM technology with up to 99% gas recombination ensures complete seal integrity and safe installation in enclosed spaces without special ventilation. F2 Faston Tab250 terminals enable fast and secure connections, while low self-discharge — under 10% in 90 days — guarantees full capacity availability after storage periods.

The operating temperature range from -15°C to 50°C ensures reliable performance across varied thermal conditions, from climate-controlled server rooms to industrial or commercial installations with limited temperature regulation. A service life of up to 5 years in standby service and high-quality material construction reduce replacement frequency in multi-unit UPS installations. IEC 61056-1/2:2012 and UL1989 certifications confirm compliance with international safety and performance standards.

Recommended as a replacement or original battery for high-performance UPS systems in data centres, server rooms, and telecommunications installations, critical applications requiring high discharge currents and extended reliability, and any UPS system where high-rate performance, a 5-year service life, and international certifications are the primary selection criteria.
