CSB GP12170 12V 17Ah Sealed Lead-Acid Battery

What is the CSB GP12170?

The CSB GP12170 is a 12 V, 17 Ah valve-regulated lead-acid (VRLA) battery with absorbent glass mat (AGM) construction from the CSB GP series (General Purpose). It is sealed and maintenance-free: it never needs water.

CSB designs this series for 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.
