2018 Camry Engine Bay
Loosen Counterclockwise
Pull Off Negative Terminal
This automotive maintenance tutorial was specifically written to assist owners of the XV70 eighth generation (2018, 2019 and possibly also the 2020, 2021 & 2022 model years) Toyota Camry sedan in changing a weak or dead 12 volt car battery for the A25A-FKS 2.5 liter inline four cylinder engine.

Owners of other Toyota, Scion and Lexus vehicles such as the Avalon, Corolla, Prius, Yaris, Mirai, 86, Sienna, RAV4, Highlander, 4Runner, C-HR, Land Cruiser, Sequoia, Tacoma, Tundra, Venza, Hilux, RX 350, IS 250, IS 350, CT 200H, GS 450h, GX 470, LX 470, UX 200, NX 300 and UX 250h may also find these DIY instructions to be helpful.

The original OEM battery was marked as Johnson Controls part number 380LN3-MF (or 28800-0P040).

A few compatible replacement group size 24F or 35 batteries with their part numbers include the following: DieHard 38275, Exide 24FC, EverStart MAXX-24F and EverStart MAXX-35N (at Walmart).

The tools needed to complete this procedure include a 10mm socket with a 1/4" drive ratchet, a 12mm socket with a long six inch or 9" extension bar and a 3/8" drive ratchet.


Cover & Tuck Away
Squeeze Two Tabs
Pull Off Red Plastic Cover
The first two steps are to open the hood and then move to the right (driver) side of the engine bay.

The 12 volt car battery is located just behind the engine air filter housing and to the left of the fuse box.

Loosen the nut on the negative terminal (closer to the rear of the engine bay) by turning it in the counterclockwise direction with a 10mm socket and a 1/4" drive ratchet.

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

Cover the terminal with a small towel and tuck it away on the left side of the battery to help prevent accidental electrical contact.

Squeeze together the two tabs on the red plastic cover before pulling it straight off the positive terminal.

Loosen Counterclockwise
Pull Off Positive Terminal
Tuck Away Side Battery
Then loosen the nut on the positive terminal by turning it a few turns in the counterclockwise direction with a 10mm socket and a 1/4" drive ratchet.

Pull the positive terminal off the "+" battery post.

Close the red plastic cover over the positive terminal and tuck it away on the side of the battery.

Long Extension Battery
Hold Down Clamp
Loosen Counterclockwise
Attach a long 6" or 9" extension bar to a 12mm socket and the 3/8" drive ratchet.

Loosen the single bolt that holds the hold down clamp at the lower front edge of the battery.

Lift Out Hold Down Bar
Battery Clamp Removed
Old Battery Removed
Lift the battery hold down bar out of the engine bay and set it aside in a safe place.

Carefully lift the old 12V battery out of the engine bay.

Gently rest the old battery 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 prevent from having to pay a "recycling fee", "core" charge or "disposal" fee.


Clean Off Plastic Tray
Lower In New Battery
Hold Down Clamp
Clean off any debris from the black plastic tray in the engine bay so that the new battery will rest evenly on it.

Carefully lower the new battery into the engine bay.

If you can wait a few days for delivery, I recommend buying the DieHard 38275 battery since it has excellent reviews on Amazon.

The positive "+" post should be closer to the front of the engine bay.

The negative "-" post should be closer to the windshield at the rear of the engine bay.

Lower the hold down clamp to the front edge of the battery tray.

Line Up Bolt & Hole
Spin In By Hand
Tighten Bolt Clockwise
Spin in the bolt a few turns by hand or with the extension bar and 12mm socket to prevent it from becoming cross threaded.

Tighten the battery hold down clamp bolt in the clockwise direction with the 12mm socket, extension bar and a 3/8" drive ratchet until it is snug.

Check to see if the new battery can be moved, slid or rocked on the tray. If it can be moved, tighten the hold down clamp bolt an extra turn or two.

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

Push On Positive Terminal
Tighten Nut Clockwise
Push On Red Plastic Cover
Push the positive terminal on to the "+" battery post.

Tighten the terminal nut in the clockwise direction with a 10mm socket and a 1/4" drive ratchet until it is snug.

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

Push On Negative Terminal
Tighten Clockwise
12V Battery Replaced
Push the negative terminal over the "-" battery post.

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

To test the new 12V battery, start the engine and turn on the headlights.

If you don't drive your car for weeks at a time, I highly recommend using a Battery Tender Junior trickle charger to help keep the battery in good condition. Lead-acid batteries last longer when they are kept fully charged.

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