Installing the New Battery
Once the old battery is removed, it’s time to install the new one. Before placing the new battery in the bracket, ensure it’s securely seated and the terminals are facing the correct direction. Next, connect the positive (red) cable to the positive terminal on the new battery.
- Repeat the process for the negative (black) cable, connecting it to the corresponding terminal on the new battery.
- Make sure all connections are secure and not loose, as this can lead to electrical issues or even a fire.
Final Checks and Rebooting
After completing the installation, double-check that all connections are secure and the battery is properly seated. Start the engine and let it run for a few minutes to charge the new battery. Once the engine is turned off, disconnect the negative cable and reconnect it to test the battery’s functionality.
