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.
The battery conditioning process ensures your battery accepts 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.
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 mobile use.
• Remove accessories that are not being used (e.g. a USB disk 
drive), as they can continue to draw power.
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.
