How to prolong your Acer Extensa 502 laptop battery?

Avoid frequent full discharges because this puts additional strain on the your Extensa 502 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 Acer Extensa 502 battery life in a laptop is mainly cause by heat rather than charge / discharge patterns.
Acer Extensa 502 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 Acer Extensa 502 battery cool. Avoid a hot car. For prolonged storage, keep the battery at a 40% charge level.
Consider removing the Extensa 502 battery from a laptop when running on fixed power. (Some laptop manufacturers are concerned about dust and moisture accumulating inside the battery casing.)
For best results, store the Acer Extensa 502 battery at 40% state-of-charge.
