Battery - North America

The original equipment battery is
maintenance free. Do not remove the cap
and do not add fluid.
Refer to the replacement number shown on
the original battery label when a new
battery is needed. See Engine Compartment
Overview 0 338 for battery location.
Stop/Start System
Vehicles equipped with a 2.7L L3B, , 5.3L L84
or 6.2L L87 are equipped with a Stop/Start
system to shut off the engine to help
conserve fuel. See Stop/Start System 0 216.
Vehicles with the Stop/Start system have an
Absorbed Glass Mat (AGM) 12-volt battery.
Installation of a standard 12-volt battery will
result in reduced 12-volt battery life. When
using a 12-volt battery charger on the 12-volt
AGM battery, some chargers have an AGM
battery setting on the charger. If available,
use the AGM setting on the charger to limit
charge voltage to 14.8 volts. Follow the
charger manufacturer s instructions.
