AGM is nice if the batteries are hard to access. Me, I will go with flooded any time you canaccess them. Cranking battery......I go for the cheapest with the engines rated capacity. If they come with a 2 year warranty, replace it at 23 months, 35 for a 3 year. The house bank if well maintained should last 5-6 yrs. A start battery provides a large current for a short period of time. Deep cycle are rated for a 20 hr period. Over 10 hrs you will get something less than the 20 hr rate. e.g. 100 Ah will give you 2.5 amps for 20 hrs. and maybe 7/hr for 6 hrs.
