If a lead acid battery heats up while charging, it can indicate a problem with the charging system or the battery itself. Overcharging can cause the battery to release hydrogen gas, which can be dangerous if it accumulates in an enclosed space.
If any of these components are not functioning properly, it can cause the battery to get hot during charging. For example, if the voltage regulator is not regulating the voltage properly, it can cause the battery to overcharge and generate excessive heat.
Thus, the maximum voltage reached determines the slope of the temperature rise in the lead-acid battery cell, and by a suitably chosen limiting voltage, it is possible to limit the danger of the “thermal runaway” effect.
Chemical energy is converted into electrical energy which is delivered to load. The lead-acid battery can be recharged when it is fully discharged. For recharging, positive terminal of DC source is connected to positive terminal of the battery (anode) and negative terminal of DC source is connected to the negative terminal (cathode) of the battery.
Sulphuric acid is consumed and water is formed which reduces the specific gravity of electrolyte from 1.28 to 1.18. The terminal voltage of each battery cell falls to 1.8V. Chemical energy is converted into electrical energy which is delivered to load. The lead-acid battery can be recharged when it is fully discharged.
Heat issues, in particular, the temperature increase in a lead-acid battery during its charging has been undoubtedly a concern ever since this technology became used in practice, in particular in the automobile industry.
