Conditioning new [laptop] battery

Before you use a battery pack for the first time, there is a
"conditioning" process that you should follow:
1.Insert the new battery without turning the computer on.
2.Connect the AC adapter and fully charge the battery.
3.Disconnect the AC adapter.
4.Turn on the computer and operate using battery power.
5.Fully deplete the battery until the battery-low warning appears.
6.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. If the computer is to be stored for more
than two weeks, you are advised to remove the battery pack from the
unit.
