Sealed lead acid batteries, especially those with gel based batteries, have the possibility of acid seeping out and causing corrosion to the materials in the surrounding areas, including the case. As such, batteries with cracked cases should always be replaced immediately.
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.
Corrosion is one of the most frequent problems that affect lead-acid batteries, particularly around the terminals and connections. Left untreated, corrosion can lead to poor conductivity, increased resistance, and ultimately, battery failure.
The shedding process occurs naturally as lead-acid batteries age. The lead dioxide material in the positive plates slowly disintegrates and flakes off. This material falls to the bottom of the battery case and begins to accumulate.
An SLA battery's case may crack for several reasons, including the fact that it is of plastic construction and is designed primarily to hold the acid and plates in place, rather than having any shock resistant capabilities.
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.
