If you’ve got gadgets that demand batteries, then chances are you’ve got batteries all over the house, and you just don’t know how much juice (aka charge) they’ve got left in them. So instead of prying open that gadget to stick a bunch of batteries in there to see if they work, which is a lot of time-consuming trial and error, not to mention not knowing which ones are really still charged, get your hands on the inexpensive IOGEAR JuiceMeter.
The JuiceMeter tests AA, AAA, C, D, N, and even 9 volt batteries. Portable enough to keep on your keychain and very simple to use.
Price: $13.62
