Jump-starting your car or being short-circuited by a tool are possible situations when a battery explosion may occur. Batteries in storage can also explode. Look at the warnings in your battery charger manual. Read on to learn more.

    Make sure you do not over-charge the battery. If the battery charger is left on too long there may be a loss of water and a build up of hydrogen gas.
