- Identify the negative terminal (marked with a minus sign) and the positive terminal (marked with a plus sign).
- Use a wrench to loosen the nut on the negative terminal. Remove the cable and push it aside.
- Repeat the same step for the positive terminal.
- Locate any brackets or clamps holding the battery in place. Use a wrench to remove them.
- Carefully lift the battery out of the tray. Batteries are heavy, so lift with care.
With the old battery removed, you are ready to install the new one. Follow the same steps in reverse order. Ensure the terminals are tight and secure.
Installing The New Battery
Installing a new car battery is a straightforward task. Follow these steps to ensure a smooth process. This guide covers everything from positioning the battery to connecting the terminals.
Positioning The Battery
First, make sure the battery tray is clean. Remove any debris or corrosion. Place the new battery on the tray. Ensure the battery terminals align with the connectors.
| Step | Action |
|---|---|
| 1 | Clean the battery tray. |
| 2 | Place the new battery on the tray. |
| 3 | Align the battery terminals. |
Connecting Terminals
Once the battery is positioned, it’s time to connect the terminals. Start with the positive terminal. Ensure the connection is tight and secure. Repeat the process for the negative terminal.
- Connect the positive terminal first.
