A similar phenomenon is that of swollen lithium ion batteries: https://duckduckgo.com/?q=swollen+battery https://duckduckgo.com/?q=swollen+battery

Does this phenomenon have an identified timespan like the capacitor plague? Is it over now? When Android was a new thing, the swollen battery was one of the many things wrong with my G1 phone. Haven't encountered it on any device since then, fortunately.

  >Does this phenomenon have an identified timespan like the capacitor plague? Is it over now? As Samsung recently demonstrated, lithium batteries are far from a solved problem. There are already reports of iPhone 8s disintegrating due to puffed batteries. We still don't fully understand the chemistry of lithium batteries, but the market keeps demanding higher energy density. There are bound to be blunders along the way. https://wccftech.com/iphone-8-swollen-batteries/ https://wccftech.com/iphone-8-swollen-batteries/

A victim here. My 2007 MacBook Pro started to swell on the bottom after a couple of years, didn't think much of it, it was a tiny bump at first, but then it almost doubled in thickness so I replaced it with a cheap Chinese knockoff (was broke at the time due to starting a startup), and the same thing happened in about a year. Lesson learned.

  same in 2009 model, i'm using it right now, (without OS X of course). there is now a 4-2mm lip on the underside where the battery panel is being pushed out. I still get about 40mins and seems to have stopped swelling so what the heck :P Anyway these days Apple sells those sort of things as "features"... lets call it a "leg gripping lip" allows lap usage at strange angles.

    As a community services announcement: you should probably replace that battery immediately. It might never burn your house down while you sleep, but someone else might read your comment and think it's okay.

      I most certainly will not. Shorting, puncture and overcharge cause lipo fires. Expansion can lead to puncture and shorting in stupid thin enclosures, this is in an inch thick unsealed enclosure with lots of give which even pops off with little force, containing a battery which has swollen around 1-2% of it's original volume. This is not a consumer advice forum, it's hacker news...

    Hey, you probably know that but just in case: charging a swollen battery is a fire hazard.

      It's ok, it swollen to it's current size 8 years ago... and hasn't changed since. It's also not restricted to it's housing because the battery compartment quite easily pops off. (non-extreme) swelling does not itself cause fire, restriction which leads to puncture or shorting does... this is not a year old 1mm thick smart phone, it's an inch thick decade old macbook.
