Ale nie w ten sposob i nie w tych warunkach, w ktorych pracuja
zazwyczaj w laptopach:

"Lithium-ion suffers from stress when exposed to heat, so does keeping
a cell at a high charge voltage. A battery dwelling above 30°C (86°F)
is considered elevated temperature and for most Li-ion, a voltage above
4.10V/cell is deemed as high voltage. Exposing the battery to high
temperature and dwelling in a full state-of-charge for an extended time
can be more stressful than cycling. (..)
Besides selecting the best-suited voltage thresholds for a given
application, Li-ion should not remain at the high-voltage ceiling of
4.20V/cell for an extended time. When fully charged, remove the battery
and allow to voltage to revert to a more natural level like relaxing
after exercise. Although a properly functioning Li-ion charger will
terminate charge when the battery is full, some chargers apply a
topping charge if the battery terminal voltage drops to a given level."

A przy tym wszystkim trzeba przeciez miec na uwadze, ze bicie rekordow
w trwalosci oryginalnych baterii nie jest w interesie producentow
laptopow i wiekszosc z nich nie specjalnie gorliwa w tworzeniu
zabezpieczen, bo w koncu zarabiaja tez na sprzedazy nowych baterii.
Dlatego trzeba zatroszczyc sie samemu.
