How to prolong your Compaq Presario CQ71 laptop battery?

1. Avoid frequent full discharges because this puts additional strain on the your Presario CQ71 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 Compaq Presario CQ71 battery life in a laptop is mainly cause by heat rather than charge / discharge patterns.
2. Compaq Presario CQ71 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.
3. Keep the lithium-ion Compaq Presario CQ71 battery cool. Avoid a hot car. For prolonged storage, keep the battery at a 40% charge level.
4. Consider removing the Presario CQ71 battery from a laptop when running on fixed power. (Some laptop manufacturers are concerned about dust and moisture accumulating inside the battery casing.)
5. For best results, store the Compaq Presario CQ71 battery at 40% state-of-charge.
