When installing a lead-acid battery, insulation measures shall be taken for the tools which are being used. When connecting, connect the electrical appliances other than the battery first, ensure there is no short circuit, and finally connect the battery.
Lead-acid storage battery will lose part of its capacity due to self-discharge. Therefore, before lead-acid battery is installed and put into use, the remaining capacity of the battery should be judged according to the battery's open circuit voltage, and then different methods should be used for supplementary charge for the battery.
This contact results in a short circuit, which can generate heat and potentially cause battery failure or fires. Thus, battery aging leads to short circuits through the degradation of materials and the formation of physical structures that allow unintended connections within the battery.
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.
