Some "accident" will lead to shorter battery life of lead-acid battery in a single test a lot, you can get a better result, but the battery pack for the series, because the capacity of the open circuit voltage, state of charge, with varying degrees of vulcanization are not the same, the difference will be expanded in the series battery group, the poor state of the single experience affects the entire group of cells, significantly reducing its life. The production line from the battery charging evo electric scooters batteries to customers after the car equipped cars using this time to go through many links, intervals of up to several months or even electric scooter batteries 24v, in this period, as did the battery supplementary electric scooter batteries, self-discharge of large quantities of accumulation of lead sulfate crystals user just bought a new battery may have even reported fee of aging batteries. Battery manufacturers select Remote scooter batteries when performing 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.

A plate sulfate electrolyte density will decrease. b. When the charging voltage rises rapidly, discharge voltage drop fast. c. plate surface color is not normal, small white particles. (Lead sulfate crystals) d. Low battery capacity. Remedy sulfation relatively minor, the charge can be balanced treatment. Sulfation more serious, you can use a small current overcharging law. That first electrolyte density adjusted to 1.208 / cm3 or less, then 0.05C10A charging when the voltage reaches 2.40V, intermittent 30min, then halve the charge current to voltage and electrolyte density remained stable, stop 20min, then 0.05C10A charge, and so forth until the battery reaches normal state.
