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, 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 time to indicate charging lead-acid battery maintenance, improved float switch constant current, and makes the charging indicator after full charge, still not fully charged, it is by increasing the float voltage to compensate. Thus, a lot of float voltage charger single cell voltage exceeds 2.35V lead-acid battery, so still a lot of oxygen evolution floating stage. The oxygen cycle lead-acid batteries and bad battery life, 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 Hebei Tianyi Electric Co., Ltd., we hope to help a friend in the same industry. Local major reason for the problem is the very group assembled Weld reduce lead-acid batteries are prone to Weld plates. And each cell has 15 single grid plate is 15 joints, a battery has six single cell, there is 90 joints, a set of batteries by the three 12V-battery, there is 270 joints . If the presence of a solder joint Weld, the single cell capacity has dropped, and then the formation of the single-cell battery backward, causing the entire battery is behind the price of lead-acid batteries, the battery will be a serious imbalance, so this set of batteries fail prematurely. Even Weld control in parts per million, 37 per set of batteries will have a set of batteries exist Weld, which is definitely not allowed. The lead-calcium alloy grid batteries, welding time will precipitate calcium and cover Weld issue, so many battery manufacturers prefer to use low-antimony alloy grid without the use of lead-calcium alloy. The grid of low-antimony alloy lower oxygen evolution of hydrogen evolution voltage, battery vent large, relatively severe dehydration, battery easier to cure.
