The battery of a car is the thing that makes it all happen in terms of getting a vehicle’s engine running. If you get to hear the car’s cranking noise, you know what happens when the battery is out of the equation. Thankfully, dealing with a dead battery isn’t a difficult task anymore.
If your car headlights are dimming or it needs jump-starts and your battery is more than three years old, it’s high time to replace your car battery. Fortunately, you can change your car battery or any part of a car at home with just a few simple steps and a spare half hour.
If your car won’t start you may need to change your car battery. Often, this happens when parts of a car has been sitting in icy conditions. Sometimes, parts of a car also struggle to start when the headlights or heated windows, mirrors and seats have put too much pressure on the battery.
Whatever the reason for the battery damage, changing your car battery yourself can save expensive garage costs.
5 Simple Steps to Replace Your Car Battery
- To avoid power flow to the battery take off the keys out of the ignition. Use your vehicle handbook guidance for parts of a car. Detect your car battery under the bonnet. Before that you may need to remove a plastic cover to access your car battery.
- Spot out the positive and negative battery terminals. The positive terminal will be attached to red wires. The negative terminal will be attached to black wires. Remove the retaining nut from the negative terminal. It’s important to disconnect the negative terminal first so as not to damage your car’s electrical system. Ensure that the nut doesn’t come into contact with the positive terminal. Cover the negative terminal with an old rag to avoid short-circuiting and electric shocks. Next, remove the retaining nut from the positive terminal. Cover this terminal with rags too.
- To remove the securing bolt that holds the car battery in place use a socket or spanner. Cover your vehicle wing with rags or an old blanket so you don’t scratch the paintwork. Use a wrench and extension bar to remove the battery securing clamp
- Disconnect the battery in a vertical position. Keep in mind that it will be heavy — car batteries often weigh around 10 kg, so you may need a friend to help you. Keep the battery upright at all times to avoid acid spillages. Insert the new battery, orienting it the same way as the old battery. Re-attach the battery securing clamp and tighten the securing bolt. Ensure that all fastenings are tight.
- Clean the battery terminals to remove any powdery build-up (corrosion). The sandpaper may be useful here. Re-attach the wires to the battery terminals, connecting the positive terminal first.
Your car should now be ready to go! Don’t forget to reset your car’s stereo, a navigation system, and clock.
