Lead-acid batteries are widely used due to their many advantages and have a high market share. However, the failure of lead-acid batteries is also a hot issue that attracts attention.
Effective repair of the battery can maximize the utilization of the battery and reduce the waste of resources. At the same time, when using lead-acid batteries, we should master the correct use methods and skills to avoid failure caused by misoperation.
Using this principle, during a positive pulse, a larger voltage value is applied to the battery, which can break the lead sulfate crystal attached to the electrode plate and turn it into lead sulfate that can participate in the charging reaction.
The crystallized lead sulfate not only does not participate in the reaction, but also adsorbs on the surface of the electrode plate, which increases the internal resistance of the battery and affects the charge and discharge performance of the battery and the battery capacity3.
Repairable failures without timely intervention will cause irreparable failures of the battery. For example, in the case of overcharging, high-concentration sulfuric acid will severely corrode the electrode plate, and even causing it to deform and permanently fail.
When a large amount of lead sulfate is not handled, it will cause a short circuit in the battery, and even crystalline materials will accumulate in the gaps of the sealed plastic shell, generating expansion force and causing the shell to rupture.
