replacement battery from ifixit draining quickly and charging slowly!
Hi all. I bought a replacement battery for my 2011 macbook pro from iFixit, and have found it to be very slow charging, and just now when operating on battery power it jumped from 80% charged down to 25% in a few seconds, and steadily drained down to 7% from there before I plugged it in.
Could I have missed a step in the battery replacement process?
Or could this be aside effect of buying an early 2011 battery for a late 2011 macbook, or vice versa? I bought the computer second hand so not entirely sure which one mine is.
Is this a good question?
