Cool story and congratulations on your work.

I gave my 2010 macbook pro to my parents when I got a new one in 2015. They still use it to surf the internet and sometimes for netflix before bedtime. Its battery is so swollen that the lid cannot close anymore.

I also bought apple care but never had any chance to use it. Very impressive for a computer without any hardware failure for 12 years.

Yeah, I would get that battery replaced... if it ruptures, that's a metal-air fire that you do not want your parents to deal with....

The battery is a massive fire hazard. Show them videos of battery fires if they don’t see the point in replacing the battery.

Apple swore up and down that the bloated battery in my 2017 MBP was not a fire hazard. But I just paid $200 to replace it (plus tax!) even though their 'trade-in value' is about $250.

It feels lousy that they charge so much for the battery since this is a safety repair, and arguably caused by the fact that there were insufficient tolerances in the original build. This battery was put in circa 2019, when they replaced the keyboard/etc., so it's not even that old. I felt like I had a gun to my head since it could be a fire hazard.

That battery is a fire hazard.
