Thinking of replacing the battery on my 2011 MBA. I don't think I have the option to go back to Apple now since 2011 MBA is considered vintage or obsolete at this point. I've read that the aftermarket battery, other than the replacement battery from Apple, is a draw of luck. Might work well in the first couple of months then just tank. So if you have yours replaced in the last few years, could you comment on how well it holds up? The brand and seller if possible? I will DIY the replacement just FYI. Thanks much!
