maintenance free battery

MF battery Silver alloy grid. Better function of discharging, Supper cold cranking performance,Long storing time,No leak of acid

maintenance free batteries

batteries feature:

1.Hydrometer:Exclusive in-built hydrometer will indicate the state of charge.

2.Explosion separator: Prevents possible explosion during the charging.Eliminates acid leakage and the inflow of dust.

3.Special liquid gas separator: Exclusive patent design collecting electrolyte vapor and returns liquid electrolyte to the reservoir.

4.Calcium-silver grids: Exclusive calcium-silver design eithout antimony,could highly resisting corrosion,the service life and storage of batteries will be more longger.

5.Heat-slwaled covers: Heat sealed design increase the case strength and rigidity and prevent leakage and contamination.

6.Polypropylene case: The case of polypropylene material is light and strong, can protect batteries from heavy shocking damage.Case design reinforced the corners and terminal bases as well as the bottom for resisting vibration and road shock damage.
