Dodgy battery?

I've a dual battery system on my 110 managed by a T-Max system. I find if I link the two batteries together the engine turns over just as I'd expect - a couple of cranks and away she goes. Am I right in thinking I need a new main battery as it's not performing standalone? Ta!

Have you swapped them over to test this theory ?

Do I take it form that that when they are not connected it doe snot crank correctly? Try as the above and swap the batteries over and see if you get the opposite effect if so you would most likely be correct in your assumption the main battery is failing.
