I am not sure if someone is know with this topic.
My battery has 390 load cycles, 2008 later Macbook 5,1 13"
I never had a noticeable decline in performance, until suddenly a month or 2 ago,
Service battery appeared and battery started to drop my PC off without a even a sleep warning.
Since, I have done several tests with battery expert, battery health and coconut battery.
My battery is according to that most of the time 98% compared to new, the 3 cells give equal voltage so it doesn't look like a broken cell.
The one day my battery (via those tools and via the mac system profiler) is good or normal, the other day it is replace now, then it is service now and it is definitely not consistant.
I have tried calibrations and so on but no avail.
It seems to me buying a new battery with the risk it isn't solved would be a waste of 129 euro's (and imitation batteries have inconsistant reviews;-)
does anyone recognise this issue?
