laptop i baterija

[red baron]

Ne bih rekao da broj punjenja/pražnjenja ne utiče na vek baterije. Ako je proizvođač deklariše na 500 ciklusa, ona će imati oko 80% kapaciteta posle tog broja.
Evo nekih članaka koji mogu koristiti.

High charge levels and elevated temperatures hasten the capacity loss.

The combination of high charge level and elevated ambient temperature presents an unfavorable condition for the battery. This explains the short lifespan of many laptop batteries.

For partially charged batteries the aging process is more gradual: for a battery with a 40% residual charge, the loss is about 4% of its capacity per year at 25°C.

When using a notebook computer running from fixed line power over extended periods, consider removing the battery and storing it in a cool place so that it is not affected by the heat produced by the computer.

Every (deep) discharge cycle decreases their capacity. The degradation is sloped such that 100 cycles leave the battery with about 75% to 85% of the original. When used in notebook computers or cellular phones, this rate of deterioration means that after two to three years the battery will have capacities too low to be still usable.
