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.
As a by-product of this reaction, hydrogen is evolved. During the first part of the charging cycle, the conversion of lead sulfate to lead and lead oxide is the dominant reaction. The final impact on battery charging relates to the temperature of the battery. Although the capacity of a lead acid battery is reduced at low temperature

AGM batteries, a form of sealed lead acid battery, offer similar maintenance-free operation. However, they are much heavier and can only be used up to 50-60% depth of discharge and still lack the battery performance of their lithium counterparts.
Lithium batteries offer a multitude of advantages over lead acid batteries, such as a longer battery life, lighter weight, higher efficiency, deeper depth of discharge, smaller size, maintenance-free operation, and more power.
For example, a 100Ah lead acid battery will only be able to provide 50Ah of usable capacity. However, that same 100Ah lithium battery will provide 100 Ah of power, making one lithium battery the equivalent of two lead acid ones.
