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.
