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-buggy battery 12v, had by increasing the constant value to 2.47V ~ 2.49V. Thus, 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, and makes the charging indicator after full charge, yet fully charged battery buggies 6v12, then by increasing the float voltage 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, so that the exhaust gas is constantly floating stage. 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 the children's car battery 6v7ah Hebei Tianyi Electric Co., Ltd., we hope to help a friend in the same industry. Electric car battery maintenance routine anti-acid chemistry bolt Maintenance: In order to achieve the purpose of anti-acid suppository anti-acid, the process will be used in anti-acid battery bolt tightening stroller, should be removed. Usually pay attention to clean, periodically (years) Remove with water not higher than 50 ℃ flush dirt on the surface of the dust plug anti-acid, must not be immersed in water. Maintenance battery slot: battery slot should always be kept clean, the newly installed battery should dry battery acid or water surface. To prevent a short circuit during initial charging, the battery should be cleaned periodically after the operation, can also be 5% of alkaline, alcohol, aliphatic hydrocarbons wipe gently.
