The sad truth for many laptop owners is that sooner or later, your laptop battery will stop holding a charge. As one of these people, I’ve been searching for a way to revive my dead battery, without having to open it up. I have found that freezing a battery for a few hours is supposed to bring it back up to around 70% of it’s original capacity. Here’s the method I used:

1. Take your battery and place it into two or three Ziploc bags ( Just in case for some reason it starts to leak).  Place it on top of a small towel inside of your freezer and let it sit for 13 hours.
2. After the 13 hours have passed, remove your battery from the freezer and pat it down with a towel until its room temperature.
   THIS IS EXTREMELY IMPORTANT! CHARGING A FROZEN BATTERY WILL RESULT IN A THERMAL RUNAWAY CASCADE AND CAUSE YOUR BATTERY TO EXPLODE!!!
3. Once at Room Temperature, completely charge and drain your battery for 4 cycles.

Easy as that! I tried this with my dead Toshiba battery and it went from holding a 5 Minute charge to an hour long charge.

Do you have any other battery success stories? Post yours in the comments!
