Not sure why everyone else is saying this works great?!? I can test the battery which the testers says is good plug it into something and that doesn’t work then I can grab two brand new batteries and the object works perfectly. I’ve tested multiple different batteries (AA, CR123, CR2) on multiple different electrical items and still have the same result. I think mine over estimates the used battery’s condition.
