I hope , I don't stress you. Can I change the battery by connecting the HP-3468A to 230VAC and making the soldering with an butan powered soldering device to avoid electrical connecting to earth? All this in hope that I don't delete the calibration, if there is still any.

That would work but is vulnerable to a power outage, I have used the method suggested by Katie Wasserman in this thread http://www.hpmuseum.org/cgi-sys/cgiwrap/...ead=176914 to replace the batteries in a 3468 and two 3421s.
