Conditioning a new battery pack
Before you use a battery pack for the first time, there is a conditioning
process that you should follow:
1. Connect the AC adapter and fully charge the battery.
2. Disconnect the AC adapter.
3. Turn on the computer and operate using battery power.
4. Fully deplete the battery until the battery-low warning appears.
5. Reconnect the AC adapter and fully charge the battery again.
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.
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.
