Solution

1. Preparation

Gather tools: socket set, multimeter, battery load tester, wire brush, safety gloves, and eye protection.
Ensure the vehicle is parked in a well-ventilated area with the engine off.

2. Remove Old Battery

Disconnect the negative (-) battery cable first to avoid short circuits.
Disconnect the positive (+) battery cable.
Remove any brackets or clamps securing the battery in place.
Carefully lift the battery out of the engine bay, ensuring not to tip it over.

3. Clean Battery Tray and Terminals

Use a wire brush to clean any corrosion from the battery terminals and battery tray.
If necessary, neutralize corrosion with a mixture of baking soda and water.

4. Install New Battery

Place the new battery in the battery tray.
Secure it with any brackets or clamps that were removed earlier.
Connect the positive (+) battery cable first, followed by the negative (-) battery cable.
Ensure all connections are tight and secure.

5. Final Checks

Start the vehicle to ensure it starts smoothly.
Check for any dashboard warning lights and ensure electrical components function correctly.
