1.Bosfa dry car batteries provide enough power to start the car no matter what weather is like (high or low temperature) and the life of this batter is more than longer than the mixture of high and low  Antimony .

2.Excellent  performance of  Lead calcium alloy plates: stable ,high electricity efficiency and corrosion.

positive plate :high density and charge longer, self  charge a little , idling operation ,more durable to charge and discharge  than general batteries ,strong resistance of gas evaporation and overheating.

3.Special plate bar materials and manufacture the crafts to make batter to resist in bumping and quaking.  protect  acid from  overflowing and discharging  acid gas everywhere. long life ,low replacement rate ,reducing  environmental pollution.
