I have a 2008 240 Sundeck currently with two marine cranking batteries, I use a NOCO genius 2 bank charger and the boat is on shore power when in the slip.
One of the batteries needs to be replaced. I recently changed my camper to lithium and have a deep cycle battery that's less than a year old sitting on the shelf.
Is there any reason I can't replace the current bad battery in my Sundeck with the deep cycle battery, leaving me with one older cranking battery which seems just fine and a newer deep cycle?
I typically turn the batteries off when in the slip, attached to the smart charger which has worked very well. I use both for starting and running and one or the other when moored off shore running sound, water pump etc. It seems a capable cranking battery will be just fine for starting and the deep cycle battery will be perfect when moored, are there any issues in the Sundeck with having different batteries on board but using both to start and run? I don't believe they are connected in parallel on the Sundeck but the boat's 40 miles away so I can't just walk out and check.
