Solution

1. Preparation

Gather tools and materials: multimeter, battery tester, socket set, and a cleaning solution for terminals.
Ensure the vehicle is parked on a flat surface and turn off the engine.
Disconnect the negative battery terminal first to prevent electrical shorts.

2. Remove the Old Battery

Using a socket set, loosen and remove the positive (+) terminal followed by the negative (-) terminal.
Remove any securing brackets or clamps holding the battery in place.
Carefully lift the battery out of the tray using proper lifting techniques.

3. Clean the Battery Tray and Terminals

Use a cleaning solution and brush to clean any corrosion from the battery tray and terminal clamps.
Ensure both battery terminals are free from corrosion and dirt.

4. Install the New Battery

Position the new battery into the tray, ensuring it is seated properly.
Reattach the securing brackets or clamps to hold the battery in place.
Connect the positive (+) terminal first, followed by the negative (-) terminal.
Tighten the terminals securely but avoid over-tightening.

5. Verify Installation and Functionality

Start the engine to check that it cranks smoothly.
Monitor the dashboard for any warning lights related to the battery or charging system.
