I have 2 batteries on my 15 foot runabout. One is used for starting, it is an 800 cranking amp marine starting battery. I bought the other one as a backup starting battery, it is a 600 cranking amp. On the side, it says "marine starting, deep cycle, RV." Can I use this backup battery to run my bilge? I will eventually add running lights to it as well, once I get those wired.
I just want to make sure that I am using the right type of battery with the boat electronics.
