Electric car battery sulfation main characteristics:. A plate sulfate electrolyte density will decrease. b. When the charging voltage rises rapidly, toy car battery, discharge voltage drop fast. c. plate surface color is not normal, toy car battery prices, 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, toy car battery manufacturers, 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.

Electric vehicle lead-acid battery voltage is too small phenomenon and countermeasures float voltage is low (less than 2.18V) or discharged when additional power, the electric toy car battery, charging less, will have the following phenomena:. A low electrolyte density b The capacity shortage c. will produce sulphate negative phenomenon, seen clearly in the small white particles (lead sulfate crystals) d. negative plates will be early expansion, early capacity recession. e. result in the early termination of life. Remedy: adjust the charge current, float voltage. Balanced charge, processing sulfation phenomenon.
