12V Battery Hack

I ran across this helpful battery hack today. It just so happens that I needed one of these little button cell batteries to bring a travel alarm clock back to life. I think I’ll probably go the cheap route and break open a (cheaper) 12V battery instead of paying double that for just one of them.

Saw this on G4 the other day. Thank you dish for giving me a free 1 week preview of G4 🙂 Now, off to find something to power w/ button cell batteries
