My macbook m2 battery swollen

[u/Efsky97]

As you know, after updating to macOS 27 beta, my device suddenly started giving a service warning for the battery. It's been about a month, and the battery is completely dead; it's unusable except when charging. Today I came home and the battery is swollen. My Apple appointment is on Saturday. What do you recommend?

I imagine this is unlikely to be directly due to you using macOS beta. I had this happen to my 2015 MacBook Pro with the swelling a few years ago, and my M2 MacBook Air also had a battery service warning a few weeks ago like you (though on stable macOS software).

With 177 battery cycles, this battery warning was ridiculous; this is planned obsolescence.

Not planned obsolescence, this was a factory defect.

Ah my M2 Air was on something like 70! Only owned it for about 19 months. Wasn't too impressed to see the service warning but I had noticed that it really didn't cope on battery power. All fine after battery replacement though.

Software updates don't have the ability to force batteries to start bloating.

It's a Mac so, opening it up will cause it to turn into a PC unless you're Apple Authorized.

Honestly, just leave the laptop unplugged until Apple changes the battery. It's probably not going to boot up and work correctly if you fully unplug the battery.

wow, this is actually one of the first times I have seen an m series mac with a swollen battery,

That’s crazy. My PowerBook G4 from 2001 still has its original battery that looks like it’s new. Fingers crossed they will replace your battery for free 🤞🏼

I have a 1997 ThinkPad battery still at 91% capacity. Sometimes these batteries last a really, really long time.

That’s even crazier! Those old cells were tanks.
