I have 3 batts on my boat, 2 starting and one house. Bought the boat this year and realized the PO had 690CA Deep Cycle batteries in it, all 3 are the same and they're Interstate's. It has twin '04 Evinrude DI's on it and they require 1,000CA for starting, so I am going to replace the batts..
My question is should I just replace the 2 that I use for starting/cranking and leave the one deep cycle for the house battery or should I just replace all 3 with all of the same type batts?
My starboard engine will charge the house batt if I put the house batt switch to ALL, so usually on the trip back in I will run the house batt on ALL to charge, so my concern is having that engine charge two different types and CA batts.
The new cranking batts have 135Ah reserve and the deep cycle that is in there has 140Ah of reserve, so it 's not a night and day difference, but I know the deep cycle will handle being charged and discharged better....although it rarely gets too discharged. I only run a depth finder, VHF and AM/FM radio off of it when sitting. Both sets of batts are Group 24, not that it makes a difference.
Just seeing if it's worth it to save $130 and only buy 2 batts for cranking instead of 3 batts. The deep cycle's that are in there now are fine, only a year old, just wondering about the charging thing with 2 different CA batts really.
Thanks.
