Product Description
Sunstone MLG series battery is designed specially to meet requirement of frequent cyclic and high temperature application such as Solar Power Plant, Home Solar System, Wind Turbine System, Telecom sites etc. We use high quality separator and silica from Europe. And we use special technology to fill acid firstly then after about 20 hours charge and discharge, fill out all acid then fill in silica separately to make sure each cell can get enough silica and complete penetration of electrolyte through separators and plates pastes from top to bottom.
