Owners of other General Motors vehicles such as the Buick Verano, Regal, LaCrosse, Cascada, Encore, Enclave, Envision, GMC Canyon, Sierra 1500, Terrain, Yukon, Denali, Savana, Spark, Sonic, Cruze, Malibu, Impala, Volt, Camaro, Corvette, SS, Trax, Equinox, Traverse, Tahoe, Suburban, Colorado, Silverado and Express may also find these DIY instructions to be helpful.

The OEM battery is an ACDelco model # 48HPG (catalog number 4180).

Other compatible "Group Size" 48 or H6 batteries with their part numbers are as follows: Bosch S6585B S6, EverStart MAXX-H6, EverStart Platinum AGM H6 (Walmart), Bosch H6-760B, AutoCraft 48H6, AutoCraft Platinum H6-AGM and Legend BAT 7548.

The tools needed to complete this procedure include a Torx T-20 screwdriver, a 10mm socket with a 1/4" drive ratchet, a 6" or 9" extension bar and a 13mm socket with a 3/8" drive ratchet.

Open the rear door on the passenger side of the SUV and slide the seat all the way back. You may also want to slide the front passenger seat all the way forward.

Release the two black plastic floor mat fasteners by rotating them 1/4 turn counterclockwise.

Flip the floor mat for the rear seats over to the driver side of the vehicle.

Set the trim panel aside in a safe place.

The 12V battery is located under the carpeted access cover.

Loosen the single screw that holds it in place by turning it counterclockwise with a Torx T-20 star bit screwdriver.

The screw will remain attached to the access cover.

Locate the black plastic battery hold down clamp or "block" on the right side of the battery. (The side closest to outside of the vehicle.)

Loosen the single bolt that secures the battery hold down clamp in place by turning it counterclockwise.

Remove the 13mm bolt and set it aside in a safe place.

First loosen the nut on the negative "-" terminal by turning it counterclockwise with a 10mm socket and a 1/4" drive ratcheting wrench.

Pull the negative terminal off the "-" battery post.

Flip open the red plastic cover on the positive terminal.

Loosen the 10mm nut on the positive "+" terminal by turning it counterclockwise a few turns.

Pull the black exhaust vent tube off the side of the battery.

Carefully lift the old battery out of the floor board and gently set it on the ground.

Try to avoid tipping over or dropping the old battery to prevent from having battery acid leak out.

Be sure to take the old battery with you to Walmart or the auto parts store to prevent from having to pay a "core" charge. The retailer will also make sure that the old battery is properly recycled.

If you've had a problem with corrosion (white or blue powder) building up on the terminals or the battery posts, consider installing some felt anti-corrosion washers over the battery posts.

Push the battery exhaust vent tube in to the hole on the left side of the battery (the side facing the rear of the SUV).

Tighten the 10mm terminal nut in the clockwise direction until it is snug.

Try to avoid over tightening the terminal nut to prevent from damaging the battery post which could lead to an acid leak.

Flip the red plastic cover closed over the positive battery terminal.

Tighten the 10mm terminal nut by turning it clockwise until it is snug.

Spin in the 13mm bolt a few turns by hand in the clockwise direction to make sure it doesn't become cross threaded.

Double check that the new battery can not be moved, slid or rocked in place. If the new battery can be moved, tighten the battery clamp bolt another turn or two.

Lower the carpeted battery access cover back in to place.

Pop the black plastic trim panel back in to place over the metal tracks for the rear seat.

Test the new 12V battery by starting the engine and turning on the headlights.

Please be sure to adjust the time on the clock and program your favorite radio station presets before you start driving.
