I'm not educated enough in this area to have any expertise, however, in my personal experience leaving a lithium-ion battery plugged all the time results in scary semi-exploded batteries that also stop working.
Would you say this is a chemistry/QA problem? Have there been advances in battery / controller technology that achieves the above?
- fao_ 10mo agoYeah I was about to say the same thing! I leave my steam deck plugged in all the time (it is my main computer) and the battery still popped (valve replaced it for free ofc)
- kqr 10mo agoHow uh, does one find out about battery problems? I almost exclusively use laptops, and I tend to leave them plugged in most of the time. I don't want a sudden lithium-ion battery fire. Can I detect ahead of time that things are going bad? (My current machine is a Thinkpad P52 if it matters, but I also use older Macbooks and newer Thinkpads and older Dell machines this way, although they're plugged in less often these days.)
- mkesper 10mo ago1. Improve longevity by charging Li-Ion only up to 85% of marketed capacity (can be configured at least on Thinkpads). 2. Open up the laptop and check if battery is swollen. After about 10 years, it's also a good idea to replace the CMOS battery before leaking. 3. Without opening, sometimes keys/trackpads don't work anymore as expected. This might be due to swollen battery packs (we had several Dells where this happened).
