Product Details

Description

Maintenance free energy storage battery uses tubular plates and gel electrolyte technology to provide better deep cycle life. The battery can also be mounted horizontally or vertically as required. This energy storage battery is a rechargeable battery that integrates the battery with a battery power storage. It is particularly well-suited for use in stand-alone systems for storing the energy generated by panels and batteries as a buffer for major consumer operations. We can provide our customers with more reliable maintenance free batteries of high quality and competitive price.
