Swollen Battery CB3-431

My CB3-431 is a beautiful Chromebook, but this year I noticed that the screen wouldn't close completely, then I noticed the laptop was rocking on the desk because the middle of the bottom was bulging out more than the rubber feet, and then the trackpad stopped working. Based on a YouTube video I found where someone disassembled this model, it looks like the bulging is right where the battery sits, meaning the battery is swelling enough to bulge the case. I'm afraid this could be a safety hazard. I tried to contact Acer support, but after entering my serial number they said this device is out of warranty, and they redirected me here. Does anyone know if there was a recall for this safety issue? Any other suggestions? I found some other questions about swollen batteries, but they're older posts and the DM links were dead.

No recall that I know of. I'm not sure I've ever heard of a recall on Acer products. How old is your Chromebook? Battery\ies will sometimes swell just due to age, it's a sign that they've gotten too low several times.

The CB3-431 is a little under three years old. The battery swelling started around the two year mark. The device is still within the Google support window, but out of Acer warranty. I'm pretty fastidious about battery charging, so I doubt it has gotten too low more than once or twice in its life. I've owned ten Chromebooks, starting with the Model T's, and never had this happen before. As I've done some searches today, though, it appears that SBS (Swollen Battery Syndrome) was a problem with a couple Acer models a few years ago.

There were issues with Lithium-Ion batteries in general for a few years, first with the fires and later with swelling. It wasn't really product specific, more like everything built during the era had lesser or greater problems. The batteries have gotten a lot smarter these days, so hopefully it's in the past. Luckily there are lots of replacement batteries available and the process isn't too difficult.

@Acer-Manny, thanks for the message. I replied to your private message. I'm new to this forum, so if I messed up and you didn't get the DM, let me know and I'll try again. I appreciate the help. For now I've unplugged the Chromebook with the swollen battery and run it down to about 50% charge to reduce risk.

I got the battery pack out of the Chromebook. Was a bit of a challenge since the battery pack had swollen and distorted the case so much that it put pressure on the screws. Attached picture shows how much the battery pack had swollen.
