Ideal is nice .
My Dad said " There is no substitute for cubic inches "
He was talking about dual 430 cubic inch Lincoln engines in his Chris Craft Roamer .
It applies to batteries .
Against advice I have given on this forum I have used an AGM battery in parallel with a conventional 12 volt .
I had a battery fail and I purchased just one .
A year later I bought another AGM so that I now had two .
I would use the group 24 with a group 27 , 29 , 49 or whatever fits .
I am 100 % AGM in everything now .
Exide Edge AGM is $ 140 at BiMart .
