Hey Folks I have a question regarding batteries. I borrowed a 'snap on' tools battery tester and I have two batteries that must be replaced. Last season I replaced port starter battery and bow thruster (they are wired in series for extra 'oomph' when engaging thruster). I went with AGM cells because I had read that they have a quick recovery when discharged. I figured this made sense for the thruster. I have recently learned that we should not mix battery types. If wet cell...all wet cells. If AGM... all AGM's That was not the case last season as I had the mix of both technologies.
I am thinking that I will replace the two bad batteries ( house and Starboard starter) with AGM. I called Carver today and spoke with Brian who mentioned that I should change the battery charging 'type' on the CHARLES 5000 charger which is permanently mounted in the engine room.
Who even knew that the unit needed to be adjusted for battery type? I must change setting to AGM. Question for the pros:
Did I damage batteries by having a mix of technologies? Since the charger is factory default to 'gel', are the batteries compromised? Is there any reason not to go with the AGM technology since all batteries in the bank will now be AGM.
What do you think? Thanks
