"It is called electrical tape because it conducts electricity"

In an ideal world, that technically would work, though you'd need to connect the ends with a wire or some sort of conductor, thus completing the circuit. However, alkaline batteries won't charge like this because attempting to reverse the chemical process that gives them their charge in the first place will produce gas bubbles, causing the battery to explode. It's the same principle as putting non-rechargeable batteries into a battery charger. (So technically, this idea should work with rechargeable batteries, or even a dead rechargeable battery and a charged non-rechargeable battery.)

The guy in the video reeks of idiocy. I want him slightly dead with a bit of garnish.

His mom catered the video shoot????

heee heee heee...

Upvote for geek.

Just a heads up... this is from the same guy that did the GMail/GoogleTV prank a week or so ago. This video is a joke, and should be labeled "Humor", not "Geek".

This has got to be a joke. look at the amount of 9V batteries he's holding at the end. It's just stupid. Who the hell would have 9 9v batteries around, just to recharge (poorly) 2 other batteries. You'd be better off just going out and buying them.
Not to mention that it takes 24 hours! lol
This is supposed to be a quick fix for when you run out of batteries. 24h recharging them kinda ruins the point of it.

added to comedy channel and the the "Are you Kidding?" playlist. LOL.

Wow, this video obviously took a little time to make just to fool some people into thinking they can recharge batteries. That's about the lamest prank ever.
