Chevrolet Silverado: Vehicle Checks / Battery - North America

Chevrolet Silverado 2019-2024 Owners Manual / Vehicle Care / Vehicle Checks / 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 for battery location.

Stop/Start System

Vehicles equipped with a 2.7L L3B, 3.0L LM2, 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.

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.

Warning

WARNING: Battery posts, terminals, and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Batteries also contain other chemicals known to the State of California to cause cancer. WASH HANDS AFTER HANDLING. For more information go to www.P65Warnings.ca.gov/passenger-vehicle.

See California Proposition Warning and the back cover.
