Battery Life Of The NETBOOK PRO

8.1.5 Battery Life Of The NETBOOK PRO

Many variables affect NETBOOK PRO power consumption and battery life. The 2200 mAh 12.6 V Lithium-Ion battery pack provides 8 to 11 hours of operation, dependent on backlight level and no use of peripheral cards or attachments. Unlike batteries using other chemistries, Lithium Ion batteries do not suddenly fail unless they have been abused in some way. The battery capacity gradually reduces over the lifetime of the battery. Typically, the capacity of a NETBOOK PRO battery pack will decline by approximately 15-20% of initial capacity over 400 charge/discharge cycles. The battery capacity also declines slowly with aging, i.e. in storage.

Conventionally, the NETBOOK PRO battery pack is considered to have reached 'end-of-life' when its capacity has declined to 50% of the pack’s initial capacity. Therefore, a NETBOOK PRO battery pack will typically reach its ‘end of life’ after approximately 1000 charging/discharge cycles (although the battery will still work for some time after this point).

8.1.5.1Charging Times

The standard NETBOOK PRO battery charging solution does not use trickle charg- ing or fast charging. The NETBOOK PRO battery pack is charged at a constant rate. The actual charge time experienced is dependant on capacity of the battery pack and the ambient temperature. The approximate charging time is 3 to 4 hours.
