Applying too much pressure on the ends
when lifting a battery could cause acid to
spill. Lift the battery with a carrier or
with your hands on the opposite corners.
Batteries contain sulfuric acid which burns
skin, eyes, and clothing.
If the acid touches someone's skin, eyes, or
clothing, immediately flush the area with water
for at least 15 minutes. If someone swallows the
acid, have him or her drink lots of milk or water
first, then Milk of Magnesia, a beaten egg, or
vegetable oil. Call a doctor immediately.
To avoid damaging your vehicle or your battery,
and to avoid injury to yourself, follow these
directions for preparing your vehicle to
jump-start and connecting the jumper cables in
the order they are given. If in doubt, call for
road service.
Preparing Your Vehicle
NOTE: also see label on battery.
1. Your vehicle has a 12-volt starting system, so
you need to use a 12-volt jumper system.
You will damage your starting motor,
ignition system, and other electrical parts if
you connect them to a 24-volt power supply
(either two 12-volt batteries in series or a
24-volt generator set).
