Recover/Extend laptop battery life, method 2
BACK
One day I noticed that my laptop battery was not lasting as long as it used to, it was down from 1hr 40mins to 1hr 5mins so I decided to have a look on google. I found that it is possible to 'recover' batteries that have lost some of their capacity to hold charge by freezing them. Bizzare I know, but I'm going to tell all those interested how I did it...
Step 1: Completely flatten the battery by using the laptop until it turns off (beware this can cause data loss! Shutdown just before 0% if data conscious).
Step 2: Put the battery in a sealable bag (or an A4 paper wallet sealed with tape!) along with a piece of toilet roll or kitchen paper (to soak up any moisture that may accumulate).
Step 3: Put in the freezer for no less that 3 hours (24 hours is recommended but I used 3 hours) and if you have any freezer packs, surround it with them to freeze it quicker.
Step 4: After the 3 or more hours in the freezer, remove the battery and put it back in the laptop for charging (wipe any condensation off it first).
The battery wont appear to charge at first but give it 10-20 mins and it should begin.
Step 5: After a full charge you should see an increase in battery level. The easiest way to check this is to remove the mains cable and look at the 'remaining time' indicator on windows.
Step 6: Repeat the whole process a few times and see how high you can get the capacity to increase. I managed 20 minutes. It doesn't sound like a lot to you but to me its a considerable amount.
NOTE: Don't freeze below 20*c (degrees celcius) because the electrolyte will freeze and damage the battery. Most freezers only go down to -18 anyway so you *should* be OK.
I had a lot of luck with this process but it doesnt mean you will as well. Not all batteries can be recovered, it depends on their age and what state they were in to begin with.
This method works for all types of batteries.
I hope this helps anyone who wants to recover their battery just as I did.
