These two plates are immersed in an aqueous solution of sulfuric acid (H2 SO4) of 30% by mass. For this reason, this battery is also referred to as a lead-acid battery.

This type of battery should be handled with care, avoiding contact with eyes, skin or clothing, due to the dangerous substances that are contained inside the batteries. Care should be taken while installing, removing, working around and disposing of lead-acid batteries in order to avoid harm to oneself and others. In addition, lead-acid batteries present environmental hazards and should be disposed of properly.
