Follow these steps again until the battery has been charged and discharged three
times.
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.
Installing and removing the battery pack
Important! Before removing the battery from the unit, connect the AC
adapter if you want to continue using your computer. Otherwise, turn
off the computer first.
To install a battery pack:
1 Align the battery with the open battery bay; make sure that the end with the
contacts will enter first, and that the top surface of the battery is facing up.
2 Slide the battery into the battery bay and gently push until the battery locks in
place.
