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.
