For our small diesels there is no reason to use anything other than deep cycle batteries. The required cranking amps is less than 200. Trojan and Deka are strong contenders though availability and cost my lead you simply use the cheapest available at Walmart or Autozone.
I am working through a failure of my battery bank. 2 different batteries in my bank of 3 have a shorted cell. They are Autozone deep cycle that have lasted almost 4 years to the day. I keep them on a marine smart charger which performs equalizing charges every 60 days. Each battery only cost about $100. I'm considering trojan wet cells. Gell, AGM and LiFePO all require more specialized charging profiles which requires a special charger and alternator. The batteries alone tend to be more expensive but then the added cost of the chargers just doesn't make it worth it to me. The wet cell technology also allows for user maintenance which should maximize the life of the battery.
