Thanks to everyone who chimed in about these issues--a good example of the expertise on this list and your willingness to share it! It's also an illustration of the adage "...be careful what you wish for".
There are so many ways to address my mixed battery issue that my head is about to explode! I think I'll return the starting battery and get another AGM Group 31 leaving me with 2 identical batteries and a charger that can handle them. I will also check out the alternator charging voltage. Given that my previous Lifeline AGM battery lasted ~ 8 years with absolutely no care whatsoever, my alternator is probably maintaining an appropriate voltage to the battery. Then I can go back to squeezing another 1/10th knot out of my SAILBOAT in our race this weekend!
