This automotive maintenance tutorial was specifically written to assist owners of the sixth generation 2019, 2020, 2021, 2022 and the revised or "face lifted" 2023 and 2024 Nissan Altima sedan in changing a weak or dead 12V automotive battery located in the PR25DD 2.5L I4 engine bay.

Owners of other Nissan, Infiniti or related Renault vehicles such as the Rogue, X-Trail, Note, Versa, Rogue Sport / Qashqai, Maxima, Sentra, Juke, Kicks, Murano, Pathfinder, Armada, Frontier, Titan, Quest, NV200, Q50, Q60, QX50, QX60 and QX80 may also find these DIY instructions to be helpful.

The OEM (original equipment manufacturer) battery "Group Size" is H5 which is also known as 47 and the Nissan / Renault part number is 24410 6CA0A (also known as 24410-6CA0A or 263001240337D).

Two compatible replacement aftermarket 12V automotive batteries with their part numbers are as follows: Bosch S6-47 and Deka 9A47 AGM.

The tools needed to replace the 12V car battery include a 10mm socket with a 1/4" drive ratchet and a 13mm socket with an extension bar and a 3/8" drive ratchet from a standard socket set.

The first two steps are to open the hood and move to the right (driver) side of the engine bay.

The 12V battery is located behind the engine air filter housing, to the left of the shock tower and to the right of the brake fluid reservoir.

I highly recommend wearing safety glasses and protective gloves while working with the 12V battery!


Loosen Counterclockwise
Pull Off Negative Terminal
Open Red Cover
Flip open the fabric cover on the top of the old battery. It is held in place by Velcro (hook and loop) fasteners.

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

Then 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.

Then flip open the red plastic cover on the "+" positive terminal.

Loosen Counterclockwise
Pull Off Positive Terminal
Set Aside + Terminal
Loosen the nut on the positive terminal a few turns in the counterclockwise direction (lefty loosey) with the 10mm socket and a 1/4" drive ratchet.

Pull the positive terminal off the "+" battery post. Flip the plastic cover closed and tuck the terminal away on the left side of the battery.

Lift Off Heat Cover
Heat Shield Removed
Locate Hold Down Clamp
Pull the fabric heat shield cover off the old battery. Set it aside in a safe place for reinstallation later on.

Locate the black metal hold down clamp on the right (driver) side of the battery tray.

13mm Silver Bolt
Extension Bar & Socket
Loosen Counterclockwise
The hold down clamp is held in place by a single silver metal 13mm bolt.

(You can also use a long Torx screwdriver to remove it. I didn't check the size. It appears to be Torx T30.)

Attach the 13mm socket to a long extension bar and a 3/8" drive ratchet.

Loosen the bolt by turning it in the counterclockwise direction.

Battery Clamp Removed
Old Battery Released
Clamp Bolt Hole
The bolt should stay attached ("captured") to the black metal hold down clamp.

Set the hold down clamp aside in a safe place.

OEM Battery Removed
Part # 24410 6CA0A
Clean Off Battery Tray
Carefully lift the old battery out of the engine bay and set it down on the ground.

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

The OEM battery was marked with the part number 24410 6CA0A.

(Renault Nissan 12V - L2 EFB 60Ah 510A (EN) Enhanced Flooded Battery Special Technology 24410 6CA0A
Part Number 263001240337D  For Nissan By Clarios LLC Milwaukee WI 53209.)

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

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

Lower In New Battery
New Battery On Tray
Line Up Clamp
Gently lower the new 12V battery into the engine bay.

The "+" positive post should be situated closer to the front of the engine bay and the "-" negative battery post should be closer to the windshield.

Slide the battery over to the left (passenger) side to make sure the bolt hole for the hold down clamp is accessible.

Tighten Clockwise - 13mm
Replace Heat Shield
Push On Positive Terminal
Lower in the hold down clamp and tighten the 13mm bolt in the clockwise direction until it is snug.

Make sure the new battery can not be rocked or moved on the tray. If the battery can be moved, tighten the hold down clamp an extra turn or two in the clockwise direction.

Lower the fabric battery heat shield box back down into place.

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

I also like using the CRC Battery Cleaner spray to clean my terminals and then protect them with the Mission Automotive corrosion preventative gel.

First, push the positive terminal on to the "+" battery post.

Tighten Clockwise 10mm
Close Red Cover
Push On Negative Terminal
Tighten the 10mm nut on the positive terminal in the clockwise direction until it is snug.

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

Close the red plastic cover over the positive terminal.

Then push the negative terminal over the "-" battery post.

Tighten Clockwise 10mm
New Battery Installed
Close Top Flap
Tighten the 10mm nut on the negative terminal by turning it in the clockwise direction (righty-tighty) until it is snug.

Double check that the two terminals are securely tightened.

Close the top flap of the heat shield box and secure it with the Velcro strip.

Velcro Fasteners
Heat Shield Secured
Battery Change Done!
If you'd like to test your alternator to make sure it is working properly to charge the new battery, use a digital multimeter.

The multimeter should read over 12V to about 12.6V when the engine is off to indicate that the battery is charged.

When the engine is running the multimeter should read any where from about 13 volts to 14 volts to indicate that the alternator is charging the battery.

Be sure to write down the battery change in your vehicle's service records.
