12v auto battery

1.silver alloy grid;extends service life
2.high quality
3,maintenance free battery

Battery of construct and features.
Exclusive in-built Hydrometer will indicate the state of charge. Exclucive patent design collecting electrolyte vapor and returns liquid electrolyte to the reservoir. Heat sealed design increase the case strength and tigidity and prevent leakage and contamination. Prevents possible explosion during the charging. Eliminates acid leakage and the inflow of dust. Exclusive calcium-silver design without antimony.could highly resisting corrosion.the service life and storage of batteries will be more lingger. The case of polypropyiene 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 vibratiom and road shock damage.

1.The maintenance free battery is made from silver alloy grid and have better function of discharging and supper cold cranking performance.

2.It has 20% longger service life(2 to 3 years) and long storing time witn no leak of acid,absolutely maintenance free,being environment protective product.

3.And it has many advantages as following:

(1)stronger resistance to corrode for more effective discharging,

(2)extremely low inner resistance for supper discharging,

(3)strong resistance to corrode as to extend the life of batteries,

(4)electrolyte can't be effected by temperature,

(5)extremely low rate of self---discharging for long storing after electrification,

(6)con-venient fixing for users having no chance to touch acid liquid,

(7)no tempature rising during regular charing,no water consuming,recombination of oxygen and hydrogen,and no liquid or gaseous acid comes into being and no pullution to environment.
