Charging, caring for and maintaining the battery
!
Only use batteries approved by Fujitsu Siemens Computers for your notebook.
Take care not to drop the batteries or otherwise damage their casing (fire risk).
If the rechargeable batteries develop a fault please stop using them immediately.
Do not touch the contacts of the batteries.
Never interconnect the positive and negative terminals of a battery.
Batteries are harmful to the environment. You should dispose of them following guidance
from your local District Council.
Information on the battery charging time is contained in the "Technical data" chapter.
You can charge the battery by connecting the notebook to the mains adapter.
The time taken to load the battery depends on its usage.
Make sure that the ambient temperature of the notebook lies within the permissible range.
You can maintain long life from your battery by allowing it to discharge fully before you recharge it
again. To do this, leave your notebook turned on when it is operated with the battery. Once the
battery is running low you will hear a warning alarm. If you do not connect the mains adapter within
five minutes of the warning alarm described above, your notebook will automatically switch off.

Storing the battery
Keep the battery pack between 0°C and +30°C (32 and 122 degrees Fahrenheit). The lower the
temperature at which the batteries are stored, the lower is the rate of self-discharge.
If you store rechargeable batteries for a longer period (longer than two months), the battery charge
level should be approx. 30%. To prevent exhaustive discharge, check the charging level of the
battery at regular intervals.
To be able to make use of the optimal charging capacity of the batteries, the battery should be
completely discharged and then fully recharged.
i
If you do not use the batteries for long periods, remove them from the notebook. Never
store the batteries in the unit.
