The OEM 12V car battery is a Group Size H6 or 48.

A few compatible replacement batteries with their part numbers are as follows: Bosch S6585B S6, Bosch S5532B, EverStart MAXX-H6 (Walmart), EverStart AGM H6, AutoCraft 48H6 and NAPA Legend BAT 7548.

The tools needed to complete this procedure include a flathead screwdriver, a deep well 10mm socket with a 1/4" drive ratchet and a standard 10mm wrench.

Pry out the smaller round button part of the three fasteners with a flathead screwdriver to unlock them.

Set the three pop rivet fasteners aside in a safe place.

(Tip - This is also an easy way to access the front turn signal light bulb socket.)

The SUV's ECU or "electronic control unit" (computer) is located on top of the 12V battery.

Remove the bolt by turning it counterclockwise with a 10mm socket and a 1/4" drive ratcheting wrench.

You might find it easier to remove the bolt by using an extension bar on the wrench.

Set the 10mm bolt aside in a safe place.

Once the computer is free from the battery hold down bar, lift it off and gently rest it on the engine cover.

Set the 10mm bolt and nut aside in a safe place.

Pull the black rubber cover off the negative terminal.

Pull the negative terminal off the "-" battery post, wrap it in a small towel and tuck it away behind the battery to help prevent accidental electrical contact.

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

My 10mm socket and ratcheting wrench wasn't able to fit over the terminal nut with that black metal bracket in the way.

Carefully lift the old battery out of the engine bay and rest it on the ground.

Try to avoid dropping or tipping over 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 avoid having to pay a "core" or "recycling" charge. The retailer will have the old battery properly recycled.

Lower the new 12V battery in to the engine bay with the positive "+" post on the left (passenger) side and the negative "-" post on the right (driver) side.

If you've had a problem with corrosion build up on the battery terminals, install some felt anti-corrosion washers on to the battery posts.

Push the positive terminal on to the "+" battery post.

Close the red rubber cover over the positive terminal.

Push the negative terminal on to the "-" battery post.

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

Lower the hold down bar or "clamp" over the new battery.

Replace the 10mm bolt in to the front of the hold down bar.

Tighten the 10mm nut and bolt in the clockwise direction until they are snug.

Try to move the new battery around on the tray. If it can be moved, wiggled or rocked, tighten the 10mm nut and bolt another turn or two.

Re-insert the 10mm bolt and tighten it in the clockwise direction to secure the ECU housing.

Make sure that the center pieces of the fasteners are raised up.

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

Please remember to adjust the time on the clock and program your favorite radio station presets before driving.
