FAQs

What batteries can this tester check?

The Faithfull Battery Tester can check D, C, AA, AAA, 9V 6F22, and 1.5V button cell batteries.

How do I know if the battery is good?

The analogue needle display indicates the battery's power level. If the needle points to 'Good,' the battery is in good condition; if it points to 'Low,' it's running low; and if it points to 'Replace,' it needs replacing.

How long should I test a battery?

Minimize the test time to prevent unnecessary battery drain.

How do I store the battery tester?

Store the tester in a dry place, away from extreme temperatures and direct sunlight.

What should I do if the tester's display is not working?

Check the battery contacts for corrosion or dirt and clean them. Ensure the battery is inserted correctly.

Is the tester suitable for rechargeable batteries?

Yes, but it will only indicate the current charge level, not the battery's overall health or capacity.

Troubleshooting

The needle does not move when a battery is inserted.

Ensure the battery is inserted correctly, making proper contact with the terminals. Check the battery's polarity.

The display gives an inconsistent reading.

Clean the battery contacts on both the tester and the battery. Try a different battery to rule out a faulty cell.
