GFMG Series£¨OPzV£©

The product is tubular GEL 2V VRLA battery, with the advantages of extra-long floating charge/cycling life, no water addition required for maintenance, wide temperature range and etc. And the improved lead paste formula can improve battery discharge ability greatly. The product extremely applies to area with severe environment (e.g. high temperature, frequent power failure, volatile grid power and etc.) or energy storage system application with complicated electric environment. So it can provide longest service life battery guarantee to users.
