Howard Howell, Gordon Messmer: To both of you thanks a lot for the insight - I'm not a pro when it comes to battery chemistry/technology. So I'm definitely grateful for information in that regard. For the sake of brevity, as a response, only a few lines: My knowledge about batteries only comes from using and maintaining them. I had extremely good experiences with a cellphone lio-on battery that I drained every 2 weeks or so for about seven years (starting 2009). Only after these many years the battery started having a slightly smaller run-time capability. It wasn't even broken at the time I replaced it with a new one: it simply lost charge a little earlier than in the beginning when I used it .. >From what I now know is that it does not seem to be a big problem to *occasionally* re-calibrate li-on batteries. Even the arstechnica page from 2014 only seems to advise against re-calibration "all the time". Nevertheless: being careful to not re-calibrate every few weeks seems to be a good idea to me now. My previously linked (and in this thread mentioned) post from a few weeks ago was probably a little too optimistic: to advise there against *frequent* re-calibrating would have been a good idea. Again: Thanks!
