Operating KEILER-1 with a rechargeable battery
Insert battery
> Insert the battery into the unit (see „Insert battery“ auf Seite 47).
Now you can switch the unit on and use it.
Removing the battery
> Switch the device off.
> To remove the battery from the KEILER-1 unit, proceed in reverse order to that for
insertion.
Operating the KEILER-1 with Power Bank
You can also operate the unit with an external power source (power bank). The power
bank must provide at least 10 W (5 V/2 A). Otherwise operational malfunctions may
occur. During this operating mode, the battery in the unit is charged. The charge level
reached is shown as a percentage on the display.
Operation without the battery inserted is feasible, but is expressly highlighted as
inadvis-
able .
NOTICE! Ingress of moisture can lead to damage to the unit.
> Make sure the battery is correctly inserted and locked.
> Follow the operating instructions for the external power source.
> Connect the external power source to the USB-C port (08) on the unit.
07. CHARGING THE BATTERY
You can charge the LIEMKE BP-K in the KEILER-1 or in the CHARGER-K charger, which is
available separately.
> Refer to the CHARGER-K operating instructions for charging the battery.
Deep discharging the battery
Avoid deep discharging the battery so as not to shorten the service life of the battery
unnecessarily. If the battery is discharged completely, charging will take significantly
longer, as very little charging current flows initially in order to not damage the battery.
