Works perfectly - great design
This battery tester worked Great - just as promised. Tried out on new batteries and they read at the top of the green range, then tested what I assumed were bad batteries and they read in the red (replace) or yellow range. I really like how the v-shaped side cradle holds the batteries in place during testing. Worked for AA-D cells. 9v batteries are tested using the metal contacts on the top, which are sized just right so you can't make a mistake.
