Changing Your Car Battery

There are many people who choose the Do-It-Yourself approach when it comes to car battery replacement. However, we highly recommend car battery replacements to be conducted by professionals as varying issues can arise from a bad installation, which could potentially cost you hundreds to thousands of dollars in repair fees. Car batteries are classified as dangerous goods and should be handled with utmost precaution, the most extreme cases leading to death. There is a reason why there are special technicians for this job. The following should only be taken as a brief guide as to changing your car battery.

Safety First

Ensure that you are wearing the appropriate PPE gear before attempting a battery replacement. These include safety Glasses, polyester clothing, safety gloves, etc.

Check the Manual

Read the Vehicle Manual to ensure you are fully informed of the specifications and requirements prior to any installation.

Check the Battery

Check to see if the problem lies with the battery, and not with the car itself. Some of the most common reasons for intermittent startups that we’ve come across have been the Alternator, Starter Motor, Fuel Pump, Terminal Corrosion, or Fuse related issues.

Radio Code/Vehicle Data

Does your vehicle require a stored PIN code or other stored data? If yes, you will need a Memory Minder to ‘hold’ this code/data for you while you replace the battery, unless of course the battery is completely dead. If you have lost the code, you will need to contact your dealership in order to retrieve this code.

Carefully Remove the Battery

Remove the battery hold down clamp. Remove the negative terminal clamp first. Remove the positive terminal clamp. Carefully remove the car battery.

Check for Battery Corrosion

Battery clamps should be free from corrosion, if there are signs of corrosion, clean the terminals with the proper solution and grease up the terminals to prevent it from reoccurring in the future. If the battery terminal clamps are damaged, replace them. Clean the battery tray.

Install New Battery

Once you have ensured that you have the correct battery, place it in the correct compartment,  making sure that the positive and the negative is facing the correct direction. (Always double check!) Connect the positive clamp to the positive post first, then the negative clamp to the negative clamp. Make sure clamps are secure.

Test the New Battery

Perform full battery test to check everything is ok. Check that the alternator is charging properly. If everything passes, you can install the hold down bracket. Ensure battery is held down and there is no movement.
