How to Revive a Dead Laptop Battery


Bring a seemingly-dead laptop battery back to life, to a usable condition, although not quite like-new. It could be almost as good as a replacement laptop battery and a lot cheaper than a universal external laptop battery.

Using a freezer – the same place you put your frozen peas and TV dinners – you could restore a dead laptop battery.

Simply follow the instructions below and save yourself some money. It will only cost you the time it takes to complete the list below. So do yourself a favour and do it yourself.

1. Place a dead laptop battery in a completely sealed plastic bag.

2. Place the bag and battery in your freezer for between 11-14 hours.

3. Remove the bag from your freezer and allow the battery return to room temperature after taking it out of the bag, this is very important.

4. If your laptop batteries are still damp dry it using a cloth or towel.

5. Place your once dead laptop batteries back into your laptop.

6. Now completely charge your battery then leave it on to discharge it completely. Repeat this step at least 3-4 times.

7. Your dead battery should be much more usable, if not totally restored.
