How long does the SuperCap of the PCD3.M3xxx protect the media and RTC from being lost?

FAQ #101426

The resources (registers, flags, timers, counters etc) and possibly the user program and the text strings/DBs on a PCD3.M3xx0 are stored in RAM. To ensure that they are not lost and that the hardware clock (where present) continues to run when there is a power failure, the PCD3s are equipped with a buffer capacitor (SuperCap).

Unfortunately the time has not been specified correctly in the manual 26/789 until version 11 of the manual. The duration is 4 hours and not 8 hours (after the SuperCap has been charged while 10 minutes).
