Product Details

A rechargeable battery, storage battery, secondary cell, or accumulator is a type of electrical battery which can be charged, discharged into a load, and recharged many times, as opposed to a disposable or primary battery, which is supplied fully charged and discarded after use. The term "accumulator" is used as it accumulates and stores energy through a reversible electrochemical reaction. Zhongneng Chengyu Power Co., Ltd. specializes in developing, producing and operating a series of Sealed Valve Regulated Maintanese Free Lead Acid Battery, gel battery, OPzV battery, OPzS battery and etc.
