CSB HRL12390WFR 12V 100Ah Sealed Lead-Acid Battery, Flame-Retardant Case

What is the CSB HRL12390WFR?

The CSB HRL12390WFR is a 12 V, 100 Ah valve-regulated lead-acid (VRLA) battery with absorbent glass mat (AGM) construction from the CSB HRL series (High Rate, Long Life). It is sealed and maintenance-free: it never needs water.

CSB designs this series for high-rate UPS and float service standby power. This part number has a flame-retardant (UL 94-V0) case as standard.
