Three stage, good.

Compare charger output voltages on the various modes to the battery maker's recommended bulk/absoprtion and float voltages. The AGM mode might be best, but it could also be the FLA or even the Gel mode could be better depending on your specific batteries. Odyssey tolerates higher voltages in each stage relative to Lifeline, for example.
