Jeep Wrangler: ENGINE COMPARTMENT / Maintenance-Free Battery
Your vehicle is equipped with a
maintenance-free battery. You will never have
to add water, and periodic maintenance is not
required.
WARNING!
- Battery fluid is a corrosive acid solution and
can burn or even blind you. Do not allow
battery fluid to contact your eyes, skin, or
clothing. Do not lean over a battery when
attaching clamps. If acid splashes in eyes
or on skin, flush the area immediately with
large amounts of water.
- Battery gas is flammable and explosive.
Keep flame or sparks away from the
battery. Do not use a booster battery or any
other booster source with an output greater
than 12 Volts. Do not allow cable clamps to
touch each other.
- Battery posts, terminals, and related accessories
contain lead and lead compounds.
Wash hands after handling.
- Vehicles with the Stop/Start system will be
equipped with two batteries. Both the main

disconnected to completely de-energize the
12 Volt electrical system.

not disconnect both batteries. To learn how
to properly disconnect, see an authorized
dealer.

the battery that the positive cable is
attached to the positive post and the negative
cable is attached to the negative post.
Battery posts are marked positive (+) and
negative (-) and are identified on the battery
case. Cable clamps should be tight on the
terminal posts and free of corrosion.

is in the vehicle, disconnect both vehicle
battery cables before connecting the
charger to the battery. Do not use a “fast
charger” to provide starting voltage.

power spike or surge in the system,
resulting in damage to essential electrical
components.
