The backup battery
The backup battery in the SIMATIC RF680M is used for retaining the application data when
the main batteries are discharged. It is a rechargeable battery that is charged together with
the main battery.
Please note that a new backup battery (in the case of an empty or removed main battery)
can only retain the data in the tag for a few minutes. It cannot be replaced because it is
permanently connected to the device.
