To answer your question about type of batteries the cold cranking amp sort of coincides with the Amp Hour rating, I suggest the biggest you and afford and the highest AH rating you can get. Never let your batteries get below 12.2 volts, thats where 50% of the AH rating has been used and will damage the batteries, I've heard of people taking them down to the 11 volt range claiming deep cycle but eventually the battery will fail. Make sure your battery connections are clean and not looking like some disease growing on the the terminals and you'll be a happy camper and so will your batteries.

Lithium is a different story
