(1) Use this innovative item to test all kinds of common use batteries (AA, AAA, C, D, 9V, Button / Coin cell) (2) Does not require battery to operate. Will run on battery that you need to test. (3) Compact size and easy to use. (4) Just place the battery on the device and analog display needle will tell you about the battery capacity. (5) If needle is on red that means replace/change the battery, on yellow means battery is low, on green means battery is good.
