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.
Charging the battery
To charge the battery, first make sure that it is correctly installed in the battery bay.
Plug the AC adapter into the computer, and connect to a mains power outlet. You
can continue to operate your computer on AC power while your battery is charging.
However, charging the battery with the computer turned off results in a significantly
faster charge time.
Note: You are advised to charge the battery before retiring for the day.
Charging the battery overnight before traveling enables you to start
the next day with a fully charged battery.
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.
