In addition, the useful lifespan of the battery is adversely affected by the
following usage patterns:
• Using the computer on constant AC power.
• 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
more than 1,000 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:
• 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 your PC 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.
