So battery on this Dell Mini 9 I got the other day has a terrible battery life, about 2 hours, I decided to do an experiement to see if sticking the battery in the freezer ACTUALLY does something useful
all testing done with no interaction of the laptop
-- day 1 --
Day one was basically starting from 0% battery to full charge and then letting it run down back to 0% and repeating this several times
Charging from 0% to 100% took 2 hours
Discharging from 100% to 0% was also 2 hours
-- day 2 --
08:30 battery placed in freezer in two bags as per guides on the internet
-- day 3 --
12:00 Battery is removed after 27 hours in the freezer and given two hours to get back to room temperature.
Charging from 0% to 100% takes 2 hours
Discharge from 100% to 0% also takes 2 hours
-- Results --
Freezing the battery has done nothing what so ever to the battery!
-- addendum --
Some people have said that I need to cycle the battery at least 4 times to see an effect, this is currently being done and the results will be posted later on. I dont think it will work...
