Laptop battery maintenance tips...

Battery Type Lithium-Ion (LiOn)
    General
    • avoid deep discharges except when resetting fuel gauge or reconditioning a battery; partial dis-/recharges are better for the battery lifetime (note: fuel gauge will slowly get inaccurate over time)
    • remove battery when on AC (due to heat)
    • avoid exposing the battery (or notebook) to excessive heat
    Charging
    • avoid charging if battery is nearly full, unless you will need its full capacity soon; keep it on the 30%-85% charged range
    • keep notebook off while charging due to heat
    • fully discharge, then fully charge battery when needed to recalibrate fuel gauge; newer battery pack models require this less often, old ones might need it as often as every 30 cycles
    Storage
    • never fully charged or discharged, ideally at about 40%
    • cool and dry, but do not freeze them: 10-15C is recommended
