Maintenance-free lead-acid battery series

One, the characteristics of the lead-acid battery( be applicable to FM, GFM, SW series)
1, Sealed:The unique sealing technique design guarantees that no leakage occur from the battery, and the safety valve can keep exterior air and dust from getting into the inner of the battery;
2, Maintenance-free: because of the unique sealing design, there is no need to add water during the service life.

3,Safety and reliability: no leakage, reliable safety valve make sure the battery more safe and reliable.;
4, Long-time service life: due to selection of lead calcium alloy for grid metal, the anti-corrosion ABS material and the good sealed technique to ensure the long life of battery
5, High quality:
1) High energy and energy density, low internal resistance and high output power;
2) Excellent charge and discharge characteristics, the self-discharge below 2% every month at*0℃;

3) Good recovery, if deep discharge or something happened to the charger, then short circuit then placed for *0 days, can also recovery capacity by using equalization charge;

4) Because of the good consistency of the internal resistance, capacity and float voltage, it is no need to use equalization charge during float charge.
