What are the important reasons for the early failure of lead-acid batteries?

Important reasons for the early failure of lead-acid batteries 1. The quality and manufacturing quality of the lead-acid batteries; 2. The charging mode of the charging equipment (chargers) matching the lead-acid batteries does not match the battery; what if the lead-acid batteries are charged Does not match the charging equipment (charger), the charging voltage is too high, and the charging time is too long, which will cause the water in the electrolyte (sulfuric acid aqueous solution) to accelerate, and the hydrogen and oxygen that appear can not be completely recombined inside the battery, thus speeding up the battery Loss of water, and increase the corrosion of the electrode plate, accelerate the aging of the battery and the occurrence of early failure. 3. The user of lead-acid battery cannot use and maintain the battery in accordance with the maintenance requirements of the battery; 4. The short-circuit of the lead-acid battery refers to the connection of the positive and negative electrodes in the lead-acid battery. The lead sulfate crystals of the negative plate grow up, and a small amount of lead sulfate remains in the separator after charging. Once the lead sulfate in the separator is reduced and called lead, if it accumulates more, the lead-acid battery will have a micro short circuit. This phenomenon is called lead-by-bridging. The single cell voltage lags behind when the micro short circuit appears lightly, and the single cell short circuit occurs in severe cases. The active material on the electrode plate expands and falls off, which will also cause the positive and negative plates to be connected.
