Odyssey and Lifeline promote differing recommendations on how best to maintain their batteries. The Boondocker power supply appears to adhere more to the Lifeline standard

If this Boondocker is the one you are reading from, you need to look at the chart on page 2. The middle stage 2 - absorption, which they call normal, is 13.6V. That is not enough Volts per the manuals you read.
I doubt that 13.6V would do anything useful on a cold AGM. My solar controllers hit 15V in absorption around freezing. In summer, I have seen as low as 13.37V. I trust my solar chargers enough to leave them unattended.
I recently STFW for a charger that I would trust to leave unattended on my AGMs. Boondocker missed the cut. I did find two, a Xantrex Truecharge 2 and a Samlex.
Can you go into more detail for your solar controller(s) charging profile?
