Help with Making a Wristwatch-Tester

[Flanker]

Would you happen to know if anything like this has been done on a large scale?

Lol, I was wondering if there was anything out there that could tell you the amount of energy left in a battery just by touching the + and - sides.

Don't they have batteries with built-in monitors? You touch the - side of the battery and a button on the side of the battery and the little graph tells you how much juice is left...

And...

Why would you want a wristwatch that doesn't do anything but monitor the battery that it already has? I can see it maybe being a portable battery monitor that will let you check other batteries, but I see no point in monitoring a hearing-aid sized battery in a wristwatch that doesnt tell time....

There are such things a battery,lightbulb, and fuse testers. take one of those apart and study how it works then make your own. your gunna need a sodering iron, get one at radio shack.
