12V VRLA



As the name suggests these batteries are called as Valve Regulated Lead Acid Batteries. These batteries are predominately used for UPS applications both in stand by use and cyclic use.

Rocket's Superior Gas recombination technology ensures that more than 90% of the electrolyte is reused resulting into very low water loss and confirms its maintenance free operation. (Dimensions & wattage chart)
