Rated 4.1 out of 5 by 10 reviewers.
Rated 5.0 out of 5.0 by Big convenience in a small package This little device accurately measures the remaining charge for every size of household battery that I own. No need to guess. No waste from batteries thrown out because of not knowing the state of their charge. The 'arm' that holds the battery in place moves easily to accommodate different sizes. And don't miss the little notch on the side for button batteries. Every eco-friendly household needs one of these. January 11, 2014
Rated 1.0 out of 5.0 by Doesn't pass the test of time bought this over a year ago and it worked. Stopped working. Kept it in kitchen drawer with all household batteries. I know it didn't wear out from heavy use. Used it maybe a dozen times. You get what u pay for. Disappointing. May 16, 2015
Rated 5.0 out of 5.0 by This battery tester works and it is easy to use! Finally! I am delighted with this battery tester. I have bought testers before that were very difficult to use. This one is simple to use and accurate. I recommend it and I recommend Home Depot carry it in its stores in a spotlighted place so other regular people can find out if the new and old batteries commingled by others in the home work or not!

Rated 4.0 out of 5.0 by just about everyone can use one Battery tester is slightly clumsy design placing the batteries in to test. So far seems accurate.Really serves the purpose. December 16, 2013
Rated 5.0 out of 5.0 by Battery Tester It works great!! Also, it saves me money because many of the batteries I tested were still good and therefore could be used some more. December 10, 2013
Rated 5.0 out of 5.0 by The battery tester works as advertised The tester allows me to test batteries and know their strength before placing them into use. There is no more guess work and swapping batteries around attempting to determine which battery is dead. January 8, 2013
Rated 4.0 out of 5.0 by Simple and works well. This battery tester is easy to use and works well on most standard size batteries; however, it does not work well for the 3V batteries. January 25, 2013
Rated 3.0 out of 5.0 by For the price, it works fine. A battery tester is a must have. For the price, this one works okay. It is a little awkward placing the battery and the area showing the results is dark. Prefer my old one but did not see one comparable. April 30, 2013
