How to boost charge AGM batteries in storage?
The manual for my Lifeline 100 Amp Hour Deep Cycle AGM 12 volt batteries says this: "While in storage, batteries should be boost charged every 90 days or when open circuit voltage drops to 12.5 vol...

I talked with Lifeline technical reps in the past. They are used to dealing with returns and issues for older and often neglected batteries. A heavy reconditioning cycle can often restore them for years of use. It seems that the low cost Noco can accomplish a reconditioning cycle.
I am certainly not an expert but if they were my batteries, I would start by a simple 14.3 complete charge. Then I would do a load test (with 100 watt incandescent bulbs). If the load test looked good, I would not do the reconditioning. Perhaps I am just overly cautious but the reconditioning seems to be harsh and a step for otherwise terminal batteries.
In any case the OP has a couple of other choices and for the future they could merely get a low cost trickle charger to maintain charge.
