Product features
Sealing structure:
Has a unique structure and adopts the advanced seal technology MF series VRLA battery, make sure not to overflow the electrolyte.

Maintenance free design:
Have good ability of oxygen cycle composite MF series VRLA battery. By charging the oxygen was almost completely absorbed when used without added moisture, there is no need to measure the density of electrolyte.

High energy density:
Due to the poor fluid design and tight assembly process, MF series valve control volume sealed lead-acid battery specific energy and greatly improve the weight ratio of energy.

Low self discharge:
MF series VRLA battery by using high purity raw materials and additives, the battery in the storage or not using the self discharge rate is greatly reduced, self discharge rate is lower than the 3%/ month.

Good performance of deep discharge recovery:
The electrolyte formula of special MF series VRLA battery, in deep discharge has good recovery characteristics.
In accordance with UL94V-0 flame retardant ABS material shell
MF series battery constant current discharge parameters
