58 - Battery pack

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.
