May I missing some thing? I read this carefully:

I do not mean "data stale" or loss communication, I talk about that driver
does not start at all, on start up: on Debian is it a script
/etc/init.d/nut what contain a row

  ! /sbin/upsdrvctl start >/dev/null 2>&1 && \
    log_progress_msg "(upsdrvctl failed)" || log_progress_msg "upsdrvctl"

I experienced several times that it is give a failure, but the upsd and
upsmon is started! I modified this row with a small function, where I
tries start driver 5 times - to be save. This idea I found also on the WEB
to correct the same situation on FreeBSD.

No, it is could be connected only through good, old RS-232C:) Other
question that here should be some problems around firmware, and as I said
aerlier it has quite a primitiv/simplified controller - cheep and dirty.
Also, may be, the new batteries could cause some problems - I could not
get exactly the same batteries what was installed originally, new
batteries are have slightly better capacity and not 100% compatible with
the old ones.
