Under normal use, the lead-acid power lead acid battery can last up to 3 years. Improper use will cause a variety of faults to form, resulting in premature obsolescence. External Sealed Maintenance Free Battery failures include shell cracks, glue cracks, joint burning, poor contact, terminal corrosion, battery explosion, etc. Internal faults include plate vulcanisation, active material shedding, self-discharge. Battery external fault is easy to detect, the phenomenon is obvious, can be repaired by simple repair, decontamination, fixing and other methods; The internal fault is not easy to detect, only when using or charging to appear certain symptoms, once produced is not easy to eliminate. Therefore, in use should be based on prevention, as far as possible to avoid internal failure.
Plate Vulcanisation
The formation of white, coarse-grained lead sulphate on the plate is called "lead sulphate hardening", or "vulcanisation". This coarse-grained lead sulphate has very poor electrical conductivity and is difficult to convert to lead dioxide and spongy pure lead under normal loading. Due to its coarse grain and large volume, it will block the active agent gap and prevent the electrolyte from penetrating, significantly increasing the internal resistance of the battery.
