I don't think you can conclusively say "Modern batteries should never swell" since there's always the possibility of manufacturing and design defects in new batteries too.
It's the battery equivalent of the halting problem in software.
No manufacturing and design process is perfect, there will always be errors. If you do find a perfect design and manufacturing process, I think you wouldn't be posting here on hackers news but would be drinking champaign with Bill Gates and Warren Buffet.
- geekles 6y agoThe word "should" implies non-conclusivity.

- barkingcat 6y ago"Never" implies conclusivity? Either way, you wouldn't use "should never" when it comes to batteries, which still has bulging, quality issues, etc throughout the entire technology industry with cell phones bulging, phones catching on fire, batteries on airplanes themselves being damaged, car batteries catching fire. It's very well known that modern lithium ion battery tech isn't all that "failsafe" so using the words "should never bulge" in this context is very deceptive. It is more likely that any battery using current battery tech in consumer devices will buldge within a certain number of charge cycles (which might be higher than the useful lifetime of the device), but it's very likely that the battery will bulge. https://www.techradar.com/news/samsung-galaxy-note-7-battery-fires-heres-why-they-exploded https://www.techradar.com/news/samsung-galaxy-note-7-battery... https://en.wikipedia.org/wiki/Boeing_787_Dreamliner_battery_problems https://en.wikipedia.org/wiki/Boeing_787_Dreamliner_battery_... https://en.wikipedia.org/wiki/Plug-in_electric_vehicle_fire_incidents https://en.wikipedia.org/wiki/Plug-in_electric_vehicle_fire_...
