This automotive maintenance tutorial was specifically written to assist owners of the fourth generation (2013, 2014, 2015, 2016 and perhaps also the revised 2017 model year) Nissan Pathfinder SUV in changing a dead 12V automotive battery in the engine bay.

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.

Loosen Positive Terminal
The first two steps are to open the hood and then move to the right side of the engine bay.

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.

Loosen Counterclockwise
Pull the positive terminal off the "+" battery post, close the red plastic cover and tuck it away on the side of the battery.

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.

Clean Off Battery Tray
Carefully lift the old OEM battery out of the engine bay and gently set it on the ground.

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.

Tighten 10mm Clockwise
Gently lower the new 12V battery in to the engine bay with the negative "-" post in the front (closest to the headlight) and the positive "+" post at the rear (closer to the windshield).

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

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