Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in a safe and well-ventilated area.
Disconnect the vehicle's ignition key and remove any accessories.

2. Battery Replacement

Tools Required: Wrench set, battery terminal cleaner, safety glasses, gloves.
Sub-steps:
1. Disconnect Battery:
  - Use a wrench to loosen and remove the negative terminal first, followed by the positive terminal.
  - Safety Warning: Always disconnect the negative terminal first to prevent short circuits.
2. Remove Old Battery:
  - If applicable, unfasten any battery hold-down brackets.
  - Carefully lift the battery out of the tray; batteries can be heavy.
3. Clean Battery Tray and Terminals:
  - Use a battery terminal cleaner to remove corrosion from the terminals and the battery tray area.
4. Install New Battery:
  - Place the new battery in the tray, ensuring it is oriented correctly.
  - Reattach the hold-down brackets if present.
5. Reconnect Battery:
  - Connect the positive terminal first, then the negative terminal.
  - Tighten the terminals securely but avoid over-tightening.

3. Test Battery and Charging System

Start the engine to ensure it turns over normally.
Use the multimeter to check the battery voltage; it should read between 13.7 to 14.7 volts with the engine running, indicating proper charging.
