Owners of other Nissan or Infiniti vehicles such as the Versa, Maxima, Juke, Rogue, Altima, Xterra, Sentra, Murano, Cube, Armada, Leaf, Quest, Frontier, Teana, 370Z, GT-R, Titan, G25, G37, M35, QX56, QX60 and M37 may also find these DIY instructions to be helpful.

The OEM battery is a Johnson Controls part number 24410JA10B or 24410-JA10B.

A few other compatible replacement "Group Size 35" batteries with their part numbers are as follows: Optima Batteries 8040-218 D35 YellowTop, Optima Batteries 8020-164 35 RedTop, Bosch S6521B S6 and EverStart MAXX-35N (Walmart).

The tools required to replace the battery include a 10mm wrench or a 10mm socket with a 1/4" drive ratchet.

The 12V car battery is located on the right (driver) side of the engine bay in front of the engine air filter box and next to the electrical fuse box.

First loosen the negative "-" terminal by turning the nut counterclockwise with a 10mm wrench or a 10mm socket with a 1/4 drive ratchet.

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

Flip open the red plastic cover on the positive "+" terminal.

Loosen the 10mm nut on the positive terminal by turning it counterclockwise.

The next step is to remove the lower nut that connects the ECU (electronic control unit) computer bracket to the left side of the battery.

Remove the nut by turning it counterclockwise with the 10mm wrench.

Then loosen the upper 10mm nut on the bracket a few turns in the counterclockwise direction.

Swing the ECU bracket up and off the battery hold down bar.

Set the two nuts aside in a safe place.

Remove the foam and fabric heat shield box from the old battery and set it aside to be re-installed later on.

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

Be sure to bring the old battery with you to the auto parts store or Walmart to avoid having to pay a "core" deposit or "disposal" fee.

The retailer will also have the old battery properly recycled.

Clean off any debris from the plastic battery tray so that the new battery will rest evenly on it.

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

Lower the heat shield box over the new battery. (I forgot that step and had to re-install it later on.)

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

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

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

Lower the battery hold down clamp over the two threaded bar ends.

Swing the ECU (computer) bracket back over the threaded bar end on the battery hold down clamp.

Replace the lower 10mm nut and tighten it in the clockwise direction. Tighten the top bracket nut in the clockwise direction.

Make sure that the new battery is securely in place. If it can be moved around, rocked, or slid on the tray, tighten the two battery clamp nuts another turn or two in the clockwise direction.

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

If you haven't already, tighten the upper nut on the ECU computer bracket in the clockwise direction.

Test the new 12V car 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.
