Remember, a secure and uninterrupted connection is crucial for your charger to function correctly.

Test the Battery

When troubleshooting your car battery charger not showing charging, one important step is to Test the Battery itself.

  • Use a digital multimeter to test the voltage of your car battery.
  • A fully charged battery should read around 12.6 volts.
  • Anything below 12 volts could indicate a weak or failing battery.
  • Ensure the battery connections are clean and tight to avoid charging issues.

By conducting a simple battery test, you can determine if the battery is the root cause of the charging problem.

Examine the Charger

When troubleshooting why your car battery charger isn’t showing signs of charging, examining the charger itself is crucial. Here are some steps to take:

  • Check the Power Source: Ensure the charger is plugged into a working outlet. If the outlet is controlled by a switch, make sure it’s turned on.
  • Inspect the Cables: Look for any frayed wires, loose connections, or damage to the cables. Faulty cables can prevent the charger from working correctly.
  • Test the Outlet: Use another electronic device to test the outlet. If the device doesn’t work, the issue may lie with the outlet, not the charger.
  • Verify Charger Settings: Make sure the settings on the charger are correct for your battery type. Incorrect settings can lead to charging issues.

By examining these aspects of your charger, you can pinpoint any potential problems and address them accordingly.


When facing charging problems with your car battery charger, remember to thoroughly check the charger itself. Ensure the power source is stable, cables are intact, outlet is functional, and charger settings match your battery type. By focusing on these charger-related factors, you can pinpoint and fix issues efficiently.
