I have a 2007 Sundancer 240, and all 4 batteries died. I didn't use the boat for a couple of months and it looks like the bilge pump stayed on and drained the batteries. (Yes, I will be replacing the bilge pump and looking for other potential issues.)
My question comes to replacing the batteries.
The boat has a switch where I can use 2 cranking batteries for the motor, and when the motor is off, I can switch it and use two other batteries for music, GPS, etc...
The boat currently has (these are the 4 dead batteries):
2 x Interstate 24M-XHD Battery 800 CCA 1000 MCA Reserve 135
2 x Interstate 27M-XHD Battery 800 CCA 1000 MCA Reserve 182
I am planning to buy:
2 x 24M 27M cranking batteries, and
2 x Interstate 27M-EFB Deep Cycle Marine Battery
The question is, if I would be able to use the deep cycle batteries to start the boat, or at least to charge the two cranking batteries if needed.
I don't know much about boats, which is why I had no idea the bilge pump would drain and pretty much kill my 4 batteries.
Any advice on the configuration I am thinking of, or should I be better off just buying all 4 batteries the same 27M 800 CCA 1000?
Thanks.
