Hi, i had the same problem with a compatible battery “GreenCell”; it dropped from 30->7%. I’ve bought an original one (which works perfectly) and changed it. I just wanted to ask you, since i bought it on ebay as an original one, if it’s like they said. Can anyone tell me? Thank you.
Hi guys. I’ve changed my MBP battery and i have the same issue. When the charge reaches 30% then it directly goes to 7% and few minutes later the MBP shutdown. I know that the battery is faulty, but i want to ask you: is this a kind of battery that get old first than a normal one? I mean, even if it drops from 30 to 7 %, now the battery lasts at least 5 hours. But after 5 cycles, the maximum capacity dropped significantly. So i’ve to consider if i can keep this faulty battery (since i use the MBP mainly at home under charge) or if i have to replace it cause it won’t last long anyway. Thank you all.
