Solution

1. Preparation

Gather necessary tools: multimeter, battery load tester, jumper cables, and wrenches.
Ensure the vehicle is in a safe area and turn off all accessories.

2. Battery Replacement

Remove Battery Terminals:
- Using a wrench, disconnect the negative terminal first, followed by the positive terminal.
- Safety Warning: Always disconnect the negative terminal first to prevent short circuits.
Remove the Battery:
- Unscrew any brackets or clamps holding the battery in place.
- Carefully lift the battery out of the tray (it can be heavy).
Install New Battery:
- Place the new battery into the tray, ensuring it is securely positioned.
- Reattach the battery brackets or clamps.
Reconnect Battery Terminals:
- Connect the positive terminal first, then the negative terminal.
- Ensure the connections are tight and free of corrosion.

3. Testing the New Battery

Start the vehicle to ensure it cranks and runs smoothly.
Use the multimeter to check the voltage; it should be around 12.6 volts or higher.
