There was this post on lifehacker today with instructions on how to revive a dead laptop battery. The video says that by sicking it in a freezer it'll come back to life. Is that really a good thing to do? Just want to make sure before I try it.

Are there any others ways to make a dead battery work?

The battery I'm talking about was drained rapidly when my converter failed and sent 130v of to much power into it. It went from a 2 and a half hour battery to a 15 minute one and died a few months later. :crying:

It doesn't sound like it would work =/ If your battery isn't holding charge, then it was probably physically damaged. I stick my AA batteries in the freezer all the time because it KEEPS the charge (those discharge over time). So I assume that doing this would SAVE the power of your battery. Reviving it doesn't sound too likely.

It might, however, with all those scares of lithium ion batteries catching fire i would cautious about doing this.

This works with hard drives too. It will only work for about one use though. My teacher's hard drive died. So we stuck it in her freezer overnight, came back the next day, hooked it up and got everything we needed off of the hard drive. There wasn't any time limit that we noticed, but if we tried to restart it, it wouldn't spin up any more.

I was under the impression that putting a battery in the freezer discharged it and putting it in the sun gives it residual charge?

If the battery wasn't over $100 I'd buy it.

Thanks for your help guys! I think I'll forget about the freezer thing. Don't want to risk my house.

Actually, batteries are like transistors: millions of them are tiny, and together give the charge. In high heat, however, these tiny "transistor-wannabes" are warped out of shape, and loose their ability to conduct and store energy. Cold does not recharge it.
