During charging, the lead-acid battery undergoes a reverse chemical reaction that converts the lead sulfate on the electrodes back into lead and lead dioxide, and the sulfuric acid is replenished. This process is known as "recharging" and it restores the battery''s capacity to store electrical energy.
Use a battery management system (BMS) to monitor the battery''s voltage and prevent over-discharging. Do not store the battery for extended periods of time without charging it. Following these safety measures, you can prevent accidents and extend the lifespan of your lithium-ion battery.
