>From the manual -

"The VOLKSLOGGER has no internal buffer against momentary power
interruptions. This has the advantage that there is no part, which
deteriorates and would have to be replaced every 2-3 years by the
manufacturer."

 

But maybe there is another internal battery for the GPS engine?

 

I found this post which indicates that the engine is a Garmin GPS25.

Just to wrap things up, this problem has beep traced to the Garmin GPS
Engine. The GPS25 engine has a battery which maintains some memory and
also runs the Real Time Clock when the device is not in use, recharging
during normal operation.

When the GPS25 battery is low (which happens more often the older the
logger is), memory in the GPS engine sometimes gets partially corrupted,
in a way that the GPS is not able to detect.

Therefore, the GPS thinks it is 1,024 weeks (about 19.6 years) before
present date.

The solution is to replace the GPS battery (in order to reduce the
probability of a re-occurrence), and reset the memory inside the GPS so
that it knows in which 19.6 year epoch it is. This is not something the
user can do.

It has nothing to do with the Volkslogger Internal Battery, but it is
perhaps worth thinking about taking the opportunity of replacing it
during the repair.

I think there will be an internal battery IN THE INSIDE of GPS engine - all
Garmin engines have internal battery.  Yes the security check would be OK
with the logger ...Ian M

The security check works fine.
There is no internal battery in a Volkslogger.

"If the internal battery has died, then the Private Key would be corrupted
and any Security Check would fail."

Try uploading to the OLC and see if the security check fails.
