1
Make sure you lot don't have a lithium-ion bombardment. Your battery has to be either Nickel-Metal Hydride (NiMH) or Nickel-Cadmium (NiCD) in lodge for this method to work. If yous practice this method with the incorrect battery, the bombardment will likely be destroyed.
- All Macs have lithium batteries, and many modern Windows computers also utilise lithium batteries.^[1]
- You shouldn't perform this process on a computer with a not-removable bombardment pack, as doing so will either require you to remove the battery (which tin void your computer's warranty) or freeze the whole reckoner (which will ruin your estimator).

Remove the battery. In near cases, yous'll remove the bottom of the laptop and unclip the battery from in that location, though your laptop may have a battery release button on the bottom instead.
iv

Place the battery in a soft material bag. You'll want to do this to add a buffer between your bombardment and the second bag you'll use.^[ii]
5
Place the bagged battery in a Ziploc bag. This will ensure that the battery doesn't get damp while freezing.
- Avoid using a regular plastic purse for this, every bit the battery may accumulate moisture in such a bag.

Leave the battery in the freezer for 10 hours. Doing and then will give the battery enough time to restore at least function of its lifespan.^[three]
- You tin can exit the bombardment in for as long every bit 12 hours, but leaving it in any longer than that may crusade the battery to leak.
vii

Recharge the battery. Once your bombardment has spent enough time in the freezer, yous tin can remove information technology, dry information technology off if needed, allow it to come up back to room temperature, and then plug it back into your laptop. Yous should be able to charge the battery from there.
