Bonsoir,
Je pense avoir la même batterie merdique sur mon MacBook 2008 Alu 13'. Je ne l'avais pas acheté chez MacWay mais directement sur Ali. Si au début elle marchait bien jusqu'à 40% restant (ensuite extinction inopinée du mac), aujourd'hui elle tient uniquement la charge le Mac en veille, sinon c'est l'extinction inopinée immédiate. Je précise que depuis qu'elle est neuve elle affiche une charge maximale de 105-115%, qui est complètement fantaisiste. La batterie d'origine avait une capacité max de 4600 mAh, celle-ci de 4904 mAh.
Voici mes résultats.
La première commande :

La seconde commande :
MacBook:~ rv$ ioreg -w0 -l | grep Capacity | tr '\n' ' | ' | awk '{print int($5/$21*100)}'
awk: division by zero
input record number 1, file
source line number 1
Et la troisième commande :
MacBook:~ rv$ ====3ème commande, le copier coller créé une erreur====
