All my "dead" batteries come up as good. I suppose they have enough charge left in them to dimly light up an old-school flashlight; but this item is not useful for testing as most of today's battery uses are in electronic devices.
It cannot detect bad batteries. The battery tester claims every battery is good. I don't know if I got a dud tester or if they are all like that.
I have a box of bad batteries and they all tested good on this meter. As others have said, the only time it registers less than good is if the battery is completely flat dead. I've thrown the meter into the box with the batteries, since it's of no more use than them.
For example, when testing four Duracell Ultra AAA alkaline cells from my Dish Network Receiver remote control, which would no longer operate the remote and which showed no remaining, useful capacity via each battery's built-in tester, all four tested 'Good.' Moreover, the construction is poor: the clamps have considerable 'slop' and do not line up properly. This tester gives a 'Good' rating to all batteries except old-fashioned carbon-zinc cells that are absolutely, completely discharged (think: your grandma's flashlight from 1970). A disgraceful product from a usually good company (I've used their excellent KVMs for years).
It looks cheap and is cheap. I guess you get what you pay for. I put ones that said "good" in my camera and it was still dead. I knew that was wrong because I knew I had bad ones in there. I went on a battery testing frenzy. I was so excited when I got this last week. Everything registered "good". I thought it was the way I was holding it or the way the batteries were placed but now after reading other reviews I know it's not me.
