CSB TPL121600FR 12V 173Ah Sealed Lead-Acid Battery, Flame-Retardant Case

What is the CSB TPL121600FR?

The CSB TPL121600FR is a 12 V, 173 Ah valve-regulated lead-acid (VRLA) battery with absorbent glass mat (AGM) construction from the CSB TPL series (Telecom Front Access). It is sealed and maintenance-free: it never needs water.

CSB designs this series for float service standby power, such as telecom backup. This part number has a flame-retardant (UL 94-V0) case as standard.
