Cheap Tubular GEL Battery

Cheap Tubular GEL Battery

OPzV 2-2500-Y Product Feature Floating design life: 20 years at 25℃ Cycle life(2V): >2000 at 80% DOD and 6000 at 25% DOD Self-discharge rate: ≤2%/Month High charge acceptance performance Wide operation temperature range: -40℃~70℃ Storage life: After fully charged, it can be storaged about 2...

Product Details

Our OPzV Series battery belong to Safety and Sealed, No electrolyte leakage will occur from terminals or case or case of any Storage Battery ensuring safe and efficient operation. Maintenance-Free operation, There is no need to add water thanks to unique gas recombination system which totally transforms the generated gas into water.

Storage batteries do not need the equalizing charge, As a result of monomer battery's interface resistance capacity and float voltage uniformity are fine.
