Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, wrench set, battery terminal cleaner, socket set.
Disconnect the negative battery cable to ensure safety while working on the electrical system.

2. Inspect and Clean Battery Terminals

Remove the battery terminals using a wrench.
Clean any corrosion from the terminals and battery posts using a battery terminal cleaner.
Reconnect the terminals securely.

3. Address Parasitic Draw

If a parasitic draw is identified, locate the circuit causing the draw by checking fuses.
Once the problematic fuse is identified, trace the circuit to find the specific component causing the drain.
Repair or replace any faulty components (e.g., switches, modules).

4. Replace Battery (if necessary)

If the battery is old or not holding a charge, consider replacing it.
Use a compatible battery, ensuring it meets the specifications for the Volvo XC60.
Install the new battery and ensure connections are tight.

5. Verify Charging System

Start the vehicle and use a multimeter to check the voltage at the battery terminals.
The voltage should read between 13.7 to 14.7 volts while the engine is running.
If the output is low, test the alternator and replace it if necessary.
