If you then strap a sc40 or sc80 between the batteries also then you have a setup that will stay charged and will always start. The SC40/80 will also drain some of your main battery too, down to a safe crank voltage (11.5 or 12.5 cant remember) before isolating between the 2 batteries which gives you a capacity that is greater than your aux battery..
This is the setup i have in my boat as i cant be bothered with the manual switch types used normally.
By the way... i wasnt sure when you said isolator whether you were talking a main switch to turn everything off or whether you were purely on about a dual battery controller / solenoid / VSR etc etc etc
Thanks
