The AGM batteries will thrive if you only drain them 50-75% and then recharge them.
This practice alone will add many more useful charging cycles over the life of the battery as compared to nearly depleted each use.

edit:
Therefore if you purchase two group 31's with each about 100 amp hours.
And say you run the terrova nonstop for 5 hours at about mid speed or less
that would be somewhere near 20 amps an hour usage times five hours.
The two batteries in a series would have supplied about 100 amp hours therefore about 50% of their charge, i do not have the amp hour usage chart of the terrova in hand therefore my figures are only estimates, maybe someone can chime in.
btw: i had seen three one year old blue top optima batteries being sold on another forum IDO, if you are in MN they may be a deal, they where group 31M three for $100 each or +20 if you did not purchase all.
I have not used that brand, i read both positive and negative feedback, yet at $100 and they still should be covered by the 24 month 100% replacement warranty.
