> Undoubtedly at least one of the readers of this story will raise alarms at the prospect of keeping a lithium battery on full charge all of the time. It's a fire hazard! It can explode!

> I have a fair bit of experience with charging batteries of many types, and with confidence I can say that these concerns are largely overblown. Any appropriately designed battery charging system will stop charging the battery once it's fully charged.

Tell that to the multitude of laptops I've owned and/or repaired because the battery swells up and pushes the keyboard and trackpad out of the chassis.

Yeah, it's not a matter of stopping charging, that is a necessary but not sufficient condition to stop the battery from exploding. It's generally keeping the battery fully charged and hot inside a device that's always plugged in and always on that does them in like this over time.
