Watch This Clip to Quickly Know the Difference!
If you suddenly find that you need some batteries and have a bunch of them laying around (maybe in your freezer) – you don’t need a fancy meter to know whether any given battery that you currently have is “good” or “bad” – all you have to do is to drop each one, vertically onto a hard, flat, smooth surface.
Watch this clip to know what kind of bounce distinguishes a charged battery from a dead one – works like a charm every time on AAA, AA, C and D batteries.
