Not sure about a string of 9v, but the best way to see if they are still good is to press it to your toung. It works well and you only get a numb feeling for a few min.

Yea, I've "tongue tested" batteries since I was really young. You eventually get really good at it and you can tell if a battery is good or bad immediately. I've tested all sorts of batteries with my tongue which is why I didn't think it would be a big deal to see if a phone wire was live using the same method =)

Gets a little awkward trying to test a D Cell though hah
