Frequently Asked Questions

Q: Does the BT-168 battery tester need its own battery to operate?

A: No — the BT-168 universal battery tester is powered directly by the battery being tested. There is no separate power source required. Simply place the battery under test against both contact points and read the meter instantly.

Q: What battery sizes does the BT-168 universal tester support?

A: The BT-168 supports all major 1.5V sizes — AAA, AA, C, and D cells — as well as 9V batteries (PP3/006P) and 1.5V miniature button cells, making it a truly universal battery checker for your home, office, or workshop.

Q: How do I read the colour-coded meter on the BT-168?

A: The analog needle points to one of three colour zones: Green means the battery is fully functional, Yellow indicates low remaining charge suitable for light use, and Red signals the battery should be replaced. If the needle does not move, ensure the battery is firmly touching both contact points before concluding it is completely discharged.

Q: How long should I hold the battery against the tester contacts?

A: Keep contact as brief as possible — just a few seconds to read the meter. Since the battery under test powers the tester itself, prolonged contact draws down the battery's charge unnecessarily.
