might get injured, if the battery explodes.
Battery fluid contains sulfuric acid. Do not allow
this fluid to come in contact with eyes, skin or
clothing. In case it does, immediately flush
affected area with water and seek medical help if
necessary.
A battery will also produce hydrogen gas, which
is flammable and explosive. Keep flames or
sparks away from battery, avoid improper
connection of jumper cables, smoking etc.
Use only impact-resistant batteries with a central
gas release cover to prevent corrosion damage and
to prevent occupants from caustic burns in the
event of an accident.

Do not loosen or remove the battery terminal
clamps while the engine is running or the key is in
the ignition lock as this could damage electrical or
electronic equipment beyond repair. All electrical
