Alkaline Battery Tester AA AAA C D 9v Button

This is the easiest tester for testing all alkaline batteries. 9v batteries get tested on the top and all the other batteries get tested by clamping in the middle as shown in the photo. This also tests 3v button cells.

When you test the batteries if the meter lands in the green it means the battery is still charged and like new. Yellow means the battery still has most of it's life left but not fully charged. Red means the battery is dead or has very little energy left.
