CAUTION:
{
Using a match near a battery can cause
battery gas to explode. People have been
hurt doing this, and some have been
blinded. Use a flashlight if you need
more light.
Be sure the battery has enough water. You
do not need to add water to the battery
installed in your new vehicle. But if a
battery has filler caps, be sure the right
amount of fluid is there. If it is low, add
water to take care of that first. If you do not,
explosive gas could be present.
Battery fluid contains acid that can burn
you. Do not get it on you. If you
accidentally get it in your eyes or on your
skin, flush the place with water and get
medical help immediately.
