I too enjoied reading that but then I've also enjoied Stephen King, Ben Vova, EE "Doc" Savage, Mike Resnick, and a host of other writers of Science Fiction.
I do agree, if you want absolute maximum battery life there is no plug and play solution..
BUT: for all practical purposes the Progressive Dynamics WiZARD controlled converters like the 9200, or the IOTA with IQ-4, in the proper size, comes mighty close.. These are pre-set for flooded wet cells. and they do a very good job of both charging and maintaining.
of "Bench" storage, the Battery Minder Plus, or Battery Tender Plus (Both (TM)) are good plug and play boxes.
These are devices I highly recommend.. They are also much better at battery maintenance than the Alternator on many vehicles.
Of course if you are a real puriest.. Well some top tier converters (3 stage PLUS) the PLUS is a thermal probe, it measures the temperature at the battery and the computer in the unit adjusts the charge parameters to account for changes in temp. A good example of that is the Xantrex Prosine 2.0 (No longer made).
And the models I've listed are NOT the only ones in the top tier.. Many others in there.
What you want to avoid is single stage jobs like the Parallex 7300.
And even with all the above: There is still no "One size fits all: For eample.. I have a Progressive Dynamics 9180 with wizard (Equal to the 9280 operationally) My motor home come with a pair of GC-2 plus a 78 Amp Hour chassis battery that when charging is in parallel That's 300 amp hours of battery (Very slightly rounded) so teh 9180 is just under 30% of total c/20 amp hour.. I've expanded the house side a bit So now I have about 600 amp hours at C/20.
That 9180 is way too big for the O/P's 2 group 27's though. (9160 for those).
