11. General Handling of Rechargeable Batteries
When handling rechargeable batteries, it is important to ensure that they are
correctly used and charged so that the capacity of the battery is fully utilised and its
service life is maintained for as long as possible. The optimal charging temperature
is approx. 20 °C.. Please also take note of the safety instructions on “Safety
Instructions“.
`
Carry out a complete discharging and charging cycle once a month, then store
the device with approx. 50% of the battery capacity. This will prevent the battery
becoming full discharged and permanently damaged or no longer capable of
being charged.
`
The device should not be charged unattended.
`
Do not position the device on sensitive or highly flammable materials during the
charging process.
`
Do not cover the notebook while charging the battery.
11.1. Battery Mode
Batteries store electrical energy in their cells and then release it again as
required. Please charge and discharge the new battery completely two
or three times consecutively to ensure that it reaches its optimum
performance!
11.1.1. Shipping Mode
The notebook is in secure transport mode after being unpacked; this prevents
accidental switching on and discharging the battery.
`
Before switching on for the first time, you must connect the supplied mains unit
and wait around 8 seconds before activating the on/off switch.
If the notebook is not switched on and the battery charging status is below 30%
for more than 14 days, it is set to transport mode to protect the battery from fully
discharging.
11.1.2. Charging the Battery
The battery is charged using the AC adapter. When the AC adapter is connected, the
battery charges automatically regardless of whether or not the notebook is switched on
or not. A complete charge takes a few hours with the notebook switched off. With the
notebook switched on, the charging process takes significantly longer.
The charging process is interrupted if the temperature gets too high.
Left-click on the battery symbol in the taskbar to display the battery
status, and, if necessary, use the
F1
key to open Windows Help.
