True, my original L3C battery is now at 25% of design capacity and it's
a fairly common practice to restart charging every time the power cord is
plugged in. It's good you name the brands that got it right though.

Except that given current laptop power consumption, the battery is nowhere
near empty when the voltage drops below the acceptable level and the
circuit is switched off. That said, any attempts at shorting will damage
the battery.
