Battery
The battery is one of the most important components of your workstation. When not plugged into a
mains outlet, the workstation runs on its built-in battery. You can increase the life of the battery by
caring for the battery properly. The average battery life is around 500 charge/discharge cycles.
You can extend the battery life by taking advantage of the available energy saving functions.
!
Only use batteries released for your workstation.
Take care not to drop the batteries or otherwise damage their casing (fire risk).
If the rechargeable batteries are defective, they must not be used.
Do not touch the contacts of the batteries.
Never interconnect the positive and negative terminals of a battery.
Used batteries must be disposed of in accordance with local regulations (special waste).
Observe the information on battery storage in the chapter "Important notes".
Performing the battery learning cycle
The battery contains electronics that continuously monitor the battery charging level and display the
current charging level. To compensate for measuring errors in the electronics, and because the
chemical properties of the battery change over time, the electronics must be recalibrated regularly.
This calibration is carried out using a battery learning cycle. Using the battery learning cycle ensures
that the maximum battery capacity can always be used. During the learning cycle a defined charging
cycle is carried out.
i
The battery learning cycle lasts between four and six hours and must not be aborted.
During this period you can not work with the workstation!
Ê Restart the workstation (switching On/Off or warm boot).
The following display briefly appears on the screen during start-up:
