How Do I Change My Car Battery?Oct 24th, 2018
- Look for build-up in the form of a whitish or blue residue around the terminal – removing this can sometimes solve issues. Note: do not touch this powder it can often contain dried sulfuric acid, which will corrode your skin.
- Verify that the battery has been given the chance to recharge by driving constantly for 30 minutes (with minimal electrical usage, including not running the air conditioner).
- Check the alternator. Some cars also have a battery meter, with the engine running, the alternator usually maintains a charge close to 13.8-14.2 volts in a properly functioning charging system. The battery should have 12.4-12.8 volts with the engine off, and with no accessory load.
- Set up a secure working environment. Park on a flat, level surface at a safe distance from traffic sparks or open flames. Put on the parking brake. Put on gloves and safety goggles.
- Remove the cigarette lighter and plug the memory keeper into socket. If you don’t have a memory keeper make sure you have all the PINs for your electronic equipment before you start. You may wish to check your car manual to see what devices may be affected.
Remove the Old Battery and Install the New One:
- Locate the battery – The battery should be located in an accessible part on either side of the car’s frame. The battery is a rectangular box with two cables attached to it. In some European cars the battery is under the matting in the trunk, or inside the fender of the wheel well.
- Identify battery terminals – Locate the positive and the negative terminals. The positive terminal will have a plus sign and the negative terminal will have a minus sign.
- Disconnect the negative terminal – Loosen the negative clamp with a wrench and slide it off of the terminal. It is important that you disconnect the negative terminal socket before the positive terminal socket. Otherwise, you may short circuit the positive terminal to a grounded part of the car.
- Disconnect the positive terminal.
- Remove the car battery and put in the new battery.
- Reconnect the positive and negative terminal.
- Tighten the clamps using a wrench.
- Close the hood – Shut the hood of your car firmly and start your car.
- Check that all the electronic devices are working properly.
