Step 2: Verify the Charger Is Functioning Properly

  • Plug the charger into a different power outlet to rule out outlet issues.
  • Look for indicator lights on the charger; consult your charger’s manual for what they mean.
  • If the charger shows no lights or behaves abnormally, consider testing with another compatible charger or replacing it.

Step 3: Test the Battery

  1. Insert the battery into the charger and observe the indicator lights.
