Batteries may look like they can't hurt you, but they can cause severe burns. Batteries generate hydrogen gas which is highly explosive--a battery can explode even under normal operating conditions. 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.

    Supervise the use the battery charger-make sure there are no flames or items that create fire in the direct vicinity.

  3. 3

    Add water to each battery cell before you hook up the charger-this will help to purge hydrogen gas from the cells.

  4. 4

    Stand back from the battery whenever possible-try not to bend over to put the jumper cables in position-stay upright with your face as far away from the battery as possible.

  5. 5

    Check the battery posts for acid corrosion--if they are corroded, do not touch them with your bare hand. Always carry your battery and the battery charger in a battery carrier.

    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.

  7. 7
