Stage One: Remove The Old Battery

Turn Off Your Car And Park It On A Flat Surface In A Secure Place

When at all possible, avoid changing your battery on the side of the road. Find a safe spot to work away from vehicles, sparks, open fires, and water. Apply the parking brake and switch off your vehicle. Remove the keys from the ignition to confirm that no electricity is being supplied to the battery.

Put On Your Safety Equipment And Pop Your Hood

Batteries include a sulfuric acid electrolyte solution, which is very corrosive, can cause skin burns, and emits dangerous hydrogen gas. To protect yourself, put on insulated work gloves and safety eyewear. Then, open your hood and, if required, prop it up with a rod.

Find The Battery

Look for the battery at one of the engine bay’s corners, near the windshield or the front bumper on either side of the vehicle. Look for the rectangular battery box with two cords linked to it. If you have a modern vehicle, the battery may be hidden under a plastic cover, so remove it if required.

First, Disconnect And Secure The Negative Connection Using A Cable Tie

To avoid electrical shorts, always remove the negative cable before the positive cable. The negative battery terminal is typically black and may be marked with a minus symbol (-). Remove the plastic cover, if applicable, then use a wrench to release the negative cable clamp and slip the cable off the termination.

After That, Disconnect The Positive Cable And Secure It With A Cable Tie

The positive terminal is usually red and may be denoted by a plus symbol (+). If your car has a plastic cover over the terminal, remove it, then use a wrench to loosen the positive cable clamp and pull the cable away from the terminal. Use a cable clamp to secure the cable to the engine bay.

Remove The Vehicle’s Battery

Examine the bracket that holds the battery in place and unplug any connectors that link the battery to the bracket. A socket wrench, the appropriate-size socket, and an extension bar may be required. Lift the batteries out of the engine bay and, if feasible, place it on a concrete surface once you’ve removed all the bolts.

To Eliminate Corrosion, Clean The Battery Terminals

Examine the terminals for powdery accumulation that might be green, blue, grey, or white. Clean the corrosion off the terminals using an emery cloth or 100-grit sandpaper until they are bright.

Purchase The Proper Replacement Battery

Take a photo of or write down any information about the old battery, such as its size, measurements, and component number. Take this information to a reliable auto parts store, such as Born Again Batteries, along with the year, make, model, and engine size of your car. They will be able to locate you with a suitable alternative

Grease The Terminals Of The New Battery And Secure It To The Bracket

Insert the new battery into the tray and fasten it to the bracket. Simply reverse the procedure of removing the battery from the bracket. Then, to prevent corrosion, apply a small layer of lithium grease to each terminal.

First, Reconnect The Positive Cable

Untie the cable knot that holds the positive cable to the engine bay, taking care not to contact the end of it to anything metal. Place the cable over the termination and secure it with a wrench. If the battery has a terminal cover, place it over it.

Next, Reconnect The Negative Cable

Removing the cable tie and reconnecting the negative cable to the negative terminal is a two-step operation. Tighten the clamp with a wrench, being careful not to let the wrench or the negative cable come into touch with anything metal, as this might result in a deadly electrical discharge.

Close Your Hood And Start Your Car

Check that you have removed all tools from beneath the hood before closing it. If you followed all of the steps correctly, and the battery was the source of any power issues, your car should start straight away. Enter the alarm code if required.
