Rechargeable battery damage blindness is the culprit industry widely circulated word is: not with the bad battery, is a bad charge. In order to meet short-term high-capacity rechargeable electric bicycle battery charging in constant current limiting in three stages, had by increasing the constant value to 2.47V ~ 2.49V. Thus, the 6-volt battery stroller, much higher than the oxygen evolution voltage battery positive plate and negative plate hydrogen evolution voltage. Some charger manufacturers' products in order to reduce the charging time indication, improved float switch constant current, stroller battery, and makes charging indicator after full charge, yet fully charged battery buggies 6v12, then by increasing the floating charge pressure to compensate. Thus, a lot of float voltage charger single cell voltage exceeds 2.35V, so the floating stage still a lot of oxygen evolution. The oxygen cycle batteries and bad, buggy battery 6v10ah, so are constantly floating stage exhaust. Constant value high, to ensure that the charging time, but the expense of water loss and cure. Users use the battery, is not guaranteed after each use, are able to charge it in time, the situation is not promptly charged occurred several times within a year, it will accumulate sulfide battery. It will have shorter battery life phenomena. Above content provided by Hebei Tianyi Electric Co., Ltd., we hope to help a friend in the same industry. Electric car battery sulfation main characteristics:. 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.

Childs battery, child car battery 6v7ah, creating resistance to the battery (quality businessmen) are provided by Hebei Tianyi Electric Co. Hebei Tianyi Electric Co., Ltd. (www.tianyidq.com) strong, credible, in Xingtai wall switch industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Tianyi Electric into the brilliant and you work for a better future!
