Hi, A few months ago my Macbook Air battery was dying. I bought a battery from iFixit, and I changed it. However, I have suffered in more than one occasion that the battery goes from fully charged (or +90%), to a power alert (2% or so), in question of minutes. I don’t see a progressive draining, but a sudden change that makes me go running around looking for a socket in panic. I’ve checked with Cocconut battery and everything seems fine. What can I do?

If you’re sure the battery is having issues then you should request a replacement battery from the iFixit Store.
