The reason the battery pack and the cells produce sulphate of analysis: When a battery discharge often over-discharge, long-term low current discharge. b. Battery left open after the injection of the electrolyte (not achieve using the state) or the end of the battery pack to charge the battery for long periods. c. plate long exposed surface. d. electrolyte is impure, or chronically elevated electrolyte density. e. When the battery is discharged, open place for too long, no supplementary charge. f. charging prolonged interruption reasons. Above content provided by Hebei Tianyi Electric Co., Ltd., we hope to help a friend in the same industry. Some "accident" will lead to shorter battery life of lead-acid battery in a single test a lot, you can get a better result, however, Xiangshan electronics batteries, battery packs for the series, because the capacity of the open circuit voltage, charge state, not the same degree of cure, the difference will be expanded in the series battery pack, electronic battery button, the poor state of the single experience affects the entire group of cells, significantly reducing its life. The production line from the battery charge to customers after the car equipped vehicles use this time to go through many links, intervals even for several months, electronics batteries, in this period, because they did not supplement the battery power, electronics battery , lead sulfate discharge generated from large accumulation of crystals user just bought a new battery may have even reported fee of aging batteries. Battery manufacturers in the implementation of the battery Depot, on the recovery of the battery is not completely eliminated. After back to back battery, battery manufacturers to re-charge and discharge test, the test often find that there are more than 60% of the cells are not in line with the conditions of the battery back to back.
