Rechargeablebattery Battery Life,battery Rechargeablebattery Rechargeablebattery
When not plugged into a mains socket, the notebook 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 about 1000 charge/discharge cycles.
You can extend the battery life by taking advantage of the available energy saving functions.
Using Battery Utility, you can limit the max. charge to 80% instead of 100% capacity by configuring
Battery Charge Mode. This will correspondingly reduce the potential battery life when discharging.
In particular, when you primarily use the laptop in one location with the mains adapter permanently
connected, we recommend configuring Battery Charge Mode to 80% in order to extend the battery life.
If you require the maximum battery life for mobile use, we recommend
configuring Battery Charge Mode to 100%.
You can find Battery Utility in the Windows start menu under Settings - Extras
and online at "https://support.ts.fujitsu.com/"

Charging, caring for and maintaining the battery

Battery Battery
The notebook's rechargeable battery can only be charged when the ambient temperature
is between 5 °C / 41 °F and max. 35 °C / 95 °F.
If the battery is regularly charged at ambient temperatures above 25 °C,
this may reduce the battery life.
You can charge the battery by connecting the notebook to the mains adapter
(see "Connecting the mains adapter", Page 17).
Please note that the rechargeable battery will not be charged if its state of charge is between
90 % and 100 %. If the state of charge of the rechargeable battery is less than 90 % and
the mains adapter is connected, the battery will be charged to 100 %.
When the battery state of charge is low, a message from the operating system appears.
If you do not connect the mains adapter within about 5 minutes of the message
appearing, your notebook will automatically switch off.

Windows also has a "Battery status meter" in the taskbar for monitoring the battery capacity. When
you place the mouse pointer on the battery symbol, the system displays the battery status.
