Owners of other Hyundai or Kia vehicles such as the Optima, Cadenza, K900, Sorento, Sportage, Sedona, Soul, Elantra, Veloster, Sonata, Azera, Tucson, Forte, Genesis, Cerato, Spectra, Accent, Sephia, i20, i30, ix35, i40 and Equus may also find these DIY instructions to be helpful.

The OEM battery is a Solite Sungwoo Automotive part # CMF68L or CMF68L-BCI.

Other compatible "Group Size" 124R 12 volt batteries with their part numbers are as follows: Hyundai 37110-24001U, EverStart (Walmart) MAXX-124R, AutoCraft Gold 24FH, Napa Legend BAT 75124R and ProStart # 24FH700PS.

The tools needed to complete this procedure include a Phillips head screwdriver, a 10mm socket, a 12mm socket, an extension bar and a 3/8" drive ratchet.

The 12V car battery is located to the left of the electrical fuse box, in front of the engine air filter box and just below the air intake assembly.

Remove the two black plastic screws on the front edge of the air intake housing by turning them counterclockwise with a flathead screwdriver.

If you have trouble removing the black plastic screws, place a flathead screwdriver under the base of the fastener while you turn the screw counterclockwise to help coax it out.

Once the two screws have been removed, gently pry out the base of the fasteners with a flathead screwdriver or a plastic pry bar tool.

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

Lift up the front edge of the air intake housing and remove the rear of it from the opening in the engine air filter box.

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

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

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

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

Flip the plastic cover closed over the positive terminal and tuck it away on the left side of the battery.

Lift the battery box or "heat shield" off the old battery and set it aside for re-installation later on.

Loosen the single bolt that holds the battery hold down bar or "clamp" to the front bottom edge of the battery by turning it counterclockwise.

Lift the battery hold down clamp off the battery tray and set it aside in a safe place.

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 Walmart or the auto parts stores to avoid having to pay a "core" or "recycling" charge. The retailer will also have the old battery properly recycled.

If you can wait a few days for delivery, I recommend buying the OEM Hyundai / Kia 37110-24001U 12V battery.

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

Gently lower the new battery in to the engine bay with the positive "+" post on the left and the negative "-" post on the right (driver) side.

Re-insert the 12mm bolt and tighten it in the clockwise direction to secure the new battery in place.

Double check that the new battery can not be moved, slid or rocked. If the new battery can be moved on the tray, tighten the hold down clamp bolt a few extra turns.

Lower the heat shield cover over the new battery.

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 to the posts.

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 or damaging the battery post which could lead to an acid leak.

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

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

Re-insert the square air intake tube at the rear of the housing in to the opening in the engine air filter box.

Lower the front edge of the air intake and line up the two fastener holes with their corresponding holes on the metal frame.

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.

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