The calibration method described on the iFixit webpage for replacing the batter says to charge the battery to 100% and keep it there for 2 hours, then drain the battery until the computer shuts off, wait 5 hours then charge it to 100%. The card that came with the battery says to drain batter below 10% then charge to 100%. Which method is the correct one?
Drain it to 10% and then charge it to 100% a lot of people say you only need to do it once but I recommend doing it twice
