Will leaving a laptop plugged in damage a battery?

Leaving a laptop plugged in all the time to an external power source will NOT damage the battery.

Should I Keep my Computer plugged in while the battery is fully charged?

Keeping your system plugged in while the battery is at 100% charge won’t be a problem if you’re working at cool temperatures. However, if the temperatures are elevated and the battery is fully charged, it can potentially damage the battery. If you remove the battery, don’t store it in a discharged state.

Should you keep a battery on a power cord 24/7?

So, if the heat matters, and modern charging sets are effective enough to bypass battery when it's been charged, thus causing no heat, one may consider keeping a device on power cord 24/7 risk-free (in context of electrons and heat and battery and stuff)? Any other factors involved? In theory, yes.

What happens if a battery is connected to the mains?

If the devices are connected to the mains, such charge losses are immediately compensated and the battery is warmed up by regular micro-charges. This accelerates its wear and tear, and performance can also suffer. During active use, the temperatures in the case and thus in the battery then rise even more.
