Diagnostic Steps

1
Inspect the battery terminals for corrosion or loose connections.
2
Use a multimeter to measure the battery voltage; it should be around 12.6 volts for a fully charged battery.
3
Attempt to jump-start the vehicle using jumper cables and another vehicle.
4
Check for any blown fuses related to the starting system.
5
Inspect the alternator belt for wear or damage, as a failing alternator can lead to battery drain.

Solution

1. Preparation

Gather tools: multimeter, jumper cables, wrench set, wire brush, safety goggles, and gloves.
Ensure the vehicle is in a safe area with adequate ventilation.
Disconnect the vehicle's negative terminal to prevent any electrical shorts.

2. Clean Battery Terminals

Remove the battery terminals, starting with the negative terminal followed by the positive.
Inspect the terminals and cables for corrosion. If corrosion is present, use a wire brush to clean the terminals thoroughly.
Reattach the terminals securely, starting with the positive terminal followed by the negative.

3. Jump-Start the Vehicle

Position another vehicle close enough to connect jumper cables without the vehicles touching.
Connect the positive cable from the working battery to the positive terminal of the dead battery.
Connect the negative cable from the working battery to a solid ground on the dead vehicle (not the battery).
Start the working vehicle and allow it to run for a few minutes before attempting to start the Volvo XC60.

4. Replace the Battery (if necessary)

If the jump-start is successful, turn off both vehicles and remove the jumper cables in reverse order.
If the battery is still dead, remove the old battery using a wrench to loosen the hold-down clamp and disconnect the terminals.
Install a new battery, ensuring the positive and negative terminals are connected correctly.
Secure the battery with the hold-down clamp and ensure it is tightly fastened.
