CSB HR 1221W F2 (12V 5Ah 21W) UPS Battery

The CSB HR 1221W F2 is a high-rate 12V 5Ah VRLA AGM battery with F2 terminals, designed for compact UPS systems requiring high-rate discharge — 21W per cell — in critical applications where equipment protection against power interruptions and reliability under intensive or cyclic use are the essential requirements. It is deployed in office UPS units and IT installations where sealed AGM technology, direct F2 terminal compatibility, and compact form factor are the primary standby battery selection criteria.

Sealed AGM technology prevents acid leakage and permits mounting in any orientation without damage risk — a critical factor in compact UPS enclosures where internal space and mounting position are dictated by the equipment chassis. Optimisation for intensive and cyclic use maintains reliability and rated capacity throughout an extended service life, reducing replacement frequency compared to standard VRLA batteries in applications with frequent discharge cycles.

The rated power of 21W per cell ensures stable energy delivery to connected equipment at the moment of battery switchover, preventing voltage fluctuations that could cause resets or failures in critical equipment. F2 Faston terminals enable fast and secure installation, reducing replacement time during preventive maintenance or emergency interventions in installations with limited access.

Recommended as a replacement or original battery for compact office UPS systems and workstations where high-rate AGM discharge and cyclic use reliability are the primary requirements, protection of critical IT equipment against unexpected power interruptions, and any F2-specification UPS system where a sealed high-rate 12V 5Ah VRLA AGM battery represents the optimal replacement solution.
