Upgrade to AGM/electrical system

[AKSTEVE70]

I am the owner of a 2013 RangerTug (R29). I am replacing the starter, thruster (both Universal UB121100 group 30H) and two (4D) house batteries. I am considering AGM for all. Is there anything I need to know or would need to do to the electrical system if I go this route? Thanks in advance for the assistance!

Swapping the starter and thruster batteries shouldn’t be an issue, but I would verify that the shore power charger settings are configured for the correct battery types. As for the 4D batteries, we did not install those at the factory, but switching them to AGM would not be a problem. Just make sure the shore power charger settings match the battery types you are installing.
