Do I have to allow the battery to completely discharge and then recharge after replacement? One site said that was appropriate way to do it.
Yes, for best results you should calibrate your battery by draining it completely and then charging it uninterrupted to 100%. Once it hits 100%, leave it plugged in for a couple more hours. Then drain it again until it shuts off automatically (make sure it doesn't go to sleep). After that, charge it up and use it normally.
But thats a myth … if I’m not wrong, only nickel battery can be calibrated, the os-systems of theses days take care of it, like with all smartphones nowadays.
@mrgrdn You might be thinking of memory effect. Calibration is still very much a thing and quite important, particularly on a new battery. Here’s some reading if you are curious!
Génial pour la livraison et pour ce tuto… j’ai un mac tout neuf ! Et un grand merci pour les bonbons :-)
