Overload Charged Battery Can Explode

On lead acid battery system they use an acid solution on their system. When this battery system is charged will produce hydrogen gas, the reaction of this chemical will written later on the below. If the rate of overcharge is small, the vents of each cell allow the dissipation of the gas. However, on severe overcharge or if ventilation is inadequate on the battery is faulty, a flammable concentration of hydrogen may remain in the cell or in the battery system. The properties of this hydrogen gas, if any spark can cause hydrogen explosion. Of course this explosion will make the battery damage and can make other dangerous expose because of the acid solution will spurt. Anyone that close to this explosion can injured by this acid.

The end of the battery will be severely swollen, and when accompanied by the case being too hot to touch, this usually indicates a malfunction on the charging system of the car. Other explosion that can happen may because of reversing or make short-circuit onto the battery, reversing of positive and negative leads will damage the battery and may to gassing and explosion.

The corrosion is caused by an imperfect seal between the plastic battery case and lead battery post allowing sulfuric acid to attack the battery post. The corrosion process is also expedited by over charging. Corrosion also can caused by factors such as, salt water, dirt, heat, and humidity in the air, a crack in the battery casing, or loose battery terminals. Inspection, cleaning and coating can prevent of corrosion on the battery terminal.
