Bow Thruster Battery Charger

[jimenet1]

2003 SeaRay 390 Motoryacht with a bow thruster powered by two dedicated 12 volt, deep cycle batteries which are connected to a factory installed battery charger. Does anyone know if the charger has an automatic cutoff so as not to over-charge the bow thruster batteries?

I have a similar set up on my 420 sedan bridge. The battery charger monitors the voltage and if it needs a charge, it applies one. If not, it goes into float mode, which periodically checks for voltage drops. In other words, it won't overcharge your batteries.
