Bateria Li-Ion może być na stałe w notebooku, nawet jeśli pracuje on
wyłącznie na zasilaczu. Tak przynajmniej pisze specjalista od tych spraw
tutaj: http://www.batteryuniversity.com/partone-23.htm . Jednak jest
pewien myk - otóż żywotność takiej baterii szybko spada wraz z
temperaturą pracy, dlatego warto jednak rozważyć jej wyjmowanie.

Cytuję z w/w artykułu:

" Should I remove the battery from the charger when full?
- Should I remove the AC when my laptop is not in use?
(Laptops use Lithium-ion) It does not matter. The charger automatically
cuts the charge current when the battery is full. A laptop may be
connected to the AC when not in use.

- Should I charge my battery partially or fully?
Does not matter. Charging in stages is acceptable. Full charge
termination occurs by reading the voltage level and charge current.
Charging a full battery is safe and does not cause harm."

I kolejne zalecenia:

"Simple Guidelines

Avoid frequent full discharges because this puts additional strain on
the battery. Several partial discharges with frequent recharges are
better for lithium-ion than one deep one. Recharging a partially charged
lithium-ion does not cause harm because there is no memory. (In this
respect, lithium-ion differs from nickel-based batteries.) Short battery
life in a laptop is mainly cause by heat rather than charge / discharge
patterns.

Batteries with fuel gauge (laptops) should be calibrated by applying a
deliberate full discharge once every 30 charges. Running the pack down
in the equipment does this. If ignored, the fuel gauge will become
increasingly less accurate and in some cases cut off the device
prematurely.

Keep the lithium-ion battery cool. Avoid a hot car. For prolonged
storage, keep the battery at a 40% charge level.

Consider removing the battery from a laptop when running on fixed power.
(Some laptop manufacturers are concerned about dust and moisture
accumulating inside the battery casing.)

Avoid purchasing spare lithium-ion batteries for later use. Observe
manufacturing dates. Do not buy old stock, even if sold at clearance
prices.

If you have a spare lithium-ion battery, use one to the fullest and keep
the other cool by placing it in the refrigerator. Do not freeze the
battery. For best results, store the battery at 40% state-of-charge."
