There are many factors affect Power Tool Battery service life, one is the production factors. In view of the specialty of lead-acid batteries for electric bicycles, Power Tool Battery Manufacturers adopt various methods. The most typical way is as follows:
1.Increase the plate number. The original design of the cell 5 or 6 tablets change to 7 or 8 tablets. The battery capacity is increased by reducing the thickness of the plate and dividing the plate and increasing the number of plate.
2.Increase the sulfuric acid density of the battery. This can provide larger current and increase the initial capacity of the battery.
3.Increase the amount and proportion of lead oxide, the active material of the positive plate.
