The fridge where you keep your cold beers can also help you revive your dying lap top battery…
Put the battery in a closed plastic bag.
Place the battery in the freezer for 12 hours.
Remove the battery from the freezer, leave it on room temperature and wipe it with a towel.
Put it back into the lap top.
Charge the battery as much as you can, and then leave the battery to drain. Repeat this 3 to 4 times.
Your dead battery will be restored!
