⅜" (4.7 x 2.5 x 1.3 cm) and weighed 0.2 oz. (8 g).

Close-up view of the Hal-Hen hearing aid button battery tester. You
pushed a button battery into the slot on the bottom. If the
battery was good, the light glowed red.
Note: it didn't matter which way you had the battery as polarity
didn't matter with this tester. Shown is a No. 13 battery being tested.
