How to Use:
1. Place your battery between the two points of the battery tester, and the easy-to-read display will tell you instantly whether you have a dud, or if you can eke out another few minutes of battery life.
2. Three result: red=replace, yellow=low power, green=good
3. If needle does not move, check that battery is touching both contacts before assuming it is completely dead.
NOTE:
1. The battery tester is activated by the battery being checked. Keep test times as short as possible, to avoid unnecessary battery drain.
2. AAA battery not included
