How it works
Insert the battery into the appropriate testing position and measurement begins automatically. The battery level is shown on the LCD display. For 9V batteries, use the dedicated bottom contacts. If the display indicates empty, ensure both contacts are properly touching before concluding the battery is depleted.
Note: Because the tester uses the tested battery as its power source, keep testing time short to minimize unnecessary discharge.
