Use this conditioning process for all new batteries, or if a battery hasn't been
used for a long time. If the computer is to be stored for more than two weeks,
you are advised to remove the battery pack from the unit.
Warning! Do not expose battery packs to temperatures below 0° C
(32° F) or above 45° C (113° F). Extreme temperatures may adversely
affect the battery pack.
By following the battery conditioning process you condition your battery to
accept the maximum possible charge. Failure to follow this procedure will
prevent you from obtaining the maximum battery charge, and will also shorten
the effective lifespan of the battery.
In addition, the useful lifespan of the battery is adversely affected by the
following usage patterns:
• Using the computer on constant AC power with the battery inserted. If you
want to use constant AC power, you are advised to remove the battery pack
after it is fully charged.
• Not discharging and recharging the battery to its extremes, as described
above.
• Frequent use; the more you use the battery, the faster it will reach the end of
its effective life. A standard computer battery has a life span of about 300
charges.
Optimizing battery life
Optimizing battery life helps you get the most out of battery operation,
prolonging the charge/recharge cycle and improving recharging efficiency. You
are advised to follow the suggestions set out below:
• Purchase an extra battery pack.
• Use AC power whenever possible, reserving battery for on-the-go use.
• Eject a PC Card if it is not being used, as it will continue to draw power (for
selected models).
• Store the battery pack in a cool, dry place. The recommended temperature
is 10° C (50° F) to 30° C (86° F). Higher temperatures cause the battery to
self-discharge faster.
• Excessive recharging decreases the battery life.
• Look after your AC adapter and battery.
Checking the battery level
The Windows power meter indicates the current battery level. Rest the cursor
over the battery/power icon on the taskbar to see the battery's present charge
level.
