Follow these seven simple steps to replace your car battery at home:

Step 1: Locate the Car Battery

Identify the battery's location; it is usually under the bonnet, but in some modern cars, it might be in different spots. Refer to your owner's manual for the exact location.

Step 2: Disconnect the Battery Terminals

Locate the positive and negative terminals on the battery. The negative terminal is marked with a (-) sign and is black, while the positive terminal has a (+) sign and is red. Use the spanner to loosen and remove the negative terminal first.

Place the new battery in the vacant slot, ensuring the terminals align correctly. Reconnect the battery holder and secure it with the screws.

Step 6: Reconnect the Battery Terminals

Start with the positive terminal, ensuring the clamp fits snugly and tightens it using the spanner. Repeat the process for the negative terminal.

Step 7: Check Electronic Systems

Cover the battery with the lid and make sure all electronic systems in your car are functioning correctly.
