Solution

1. Preparation

Tools Required: Multimeter, battery load tester, socket set, wire brush.
Ensure the vehicle is parked on a flat surface and the ignition is off.

2. Visual Inspection

Carefully inspect the battery for visible signs of damage or corrosion.
Clean any corrosion from the battery terminals with a wire brush.

3. Check Voltage

Connect the multimeter leads to the battery terminals (red to positive, black to negative).
Read the voltage; it should ideally be between 12.4 and 12.7 volts for a healthy battery.

4. Load Test

Connect the battery load tester according to the manufacturer’s instructions.
Apply a load equal to half of the battery's CCA (Cold Cranking Amps) rating for 15 seconds.
Monitor the voltage drop; it should not fall below 9.6 volts during the test.

5. Check Connections

Inspect battery terminals and cables for tightness.
If any loose connections are found, tighten them securely.

6. Test with OBD-II Scanner

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Check for any battery-related trouble codes and address them accordingly.
