CSB HR1232WF2 12V 8Ah Sealed Lead-Acid Battery

What is the CSB HR1232WF2?

The CSB HR1232WF2 is a 12 V, 8 Ah valve-regulated lead-acid (VRLA) battery with absorbent glass mat (AGM) construction from the CSB HR series (High Rate). It is sealed and maintenance-free: it never needs water.

CSB designs this series for high-rate UPS and float service standby power. A flame-retardant case is available on request.

CSB lists this part as a non-stock item, so availability and minimum order quantity are confirmed with your quote.
