How to change a car battery all by yourself?

Changing a car battery is a simple task that can be done by yourself, even if you're not a mechanic or have limited automotive knowledge. Here are the steps to follow.

  • Safety First: Before you start off with the process of car battery change, make sure the car is parked on a level surface and the engine is turned off. Wear gloves, safety goggles, and protective clothing to prevent injury.
  • Locate the battery: The car battery is typically located under the hood on either side of the engine compartment. If you’re unsure, consult the owner’s manual or a mechanic.
  • Disconnect the battery: Before removing the battery, disconnect the negative cable first. It’s usually black and has a minus sign (-) on it. Loosen the clamp using a wrench, then slide it off the battery terminal. Be careful not to let the cable touch any metal parts of the car.
  • Disconnect the positive cable: Once the negative cable is disconnected, do the same with the positive cable, which is usually red and has a plus sign (+) on it. Loosen the clamp using a wrench, then slide it off the battery terminal.
  • Remove the battery: Use a battery strap or handle to lift the battery out of its tray. Be sure to hold it securely to prevent dropping or tipping it over. If the battery is heavy or difficult to lift, ask for help.
  • Clean the battery tray: Wipe the battery tray with a clean, damp cloth to remove any dirt or debris. This will help prevent corrosion and ensure a secure fit for the new battery.
  • Install the new battery: Place the new battery in the tray and tighten the hold-down clamp. Be sure the battery is secure and won’t move or vibrate while driving.
  • Reconnect the positive cable: Slide the positive cable back onto the positive terminal and tighten the clamp with a wrench. Make sure the connection is tight to ensure proper electrical contact.
  • Reconnect the negative cable: Slide the negative cable back onto the negative terminal and tighten the clamp with a wrench. Again, make sure the connection is tight.
  • Test the battery: Start the engine and make sure the battery is working properly. If the engine doesn’t start, check the connections and try again. If the battery is still not working, it may be defective and need to be replaced.

Changing a car battery is a straightforward process that can be done by anyone with a basic understanding of automotive maintenance. By following these simple steps, you can save time and money by replacing the battery yourself instead of taking it to a mechanic. Just remember to prioritise safety and take your time to ensure everything is done correctly.

Booked my service on the MySyara app. Had my car picked up and serviced with no hassles and dropped off within 4 hours. The price was reasonable considering the service quality and quick turn around time.

Yasir Khan

As a personal trainer my schedule is tight. MySyara helped me schedule car washes while I was training my clients. The service was excellent and was a fan of not being in the usual car wash line.

Arun Tewary

I gave my Nissan Patrol to MySyara 2 days back for some maintenance work. They were so prompt professional and reasonable that it’s hard to believe. Entire operation was carried out by them in a spotless manner, right from picking up my car from my place, regular updates, suggestions and timely job completion and delivery. The team was simply superb, so courteous and friendly. Most definitely I will continue to use the services of MySyara always.

I needed my car battery changed and they sorted everything out for me in a matter of minutes. I was extremely impressed by how transparent they were and how they went out of their way to educate me about the different batteries and their impact on the car. For someone who knows next to nothing about cars, I think I have found my go-to for all car related inquiries as they provide a large array of services. Their professionalism and honesty is refreshing and is an added bonus to their impeccable service.
