CSB XTV12200-WT 12V 20Ah Sealed Lead-Acid Battery

What is the CSB XTV12200-WT?

The CSB XTV12200-WT is a 12 V, 20 Ah valve-regulated lead-acid (VRLA) battery with absorbent glass mat (AGM) construction from the CSB XTV-WT series (Extreme Temperature Resistant, Wind Turbine). It is sealed and maintenance-free: it never needs water.

CSB designs this series for wind turbine applications. 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.
