Duralast Marine Deep Cycle + Starting, sold at auto-zone, have a good warranty. Reserve Minutes 210, Amp Hours 125, MCA 875, CCA is obviously lower. I tried to get them out of the battery box far enough to read the CCA, but it will require dumping them out.
When I bought them they were about $65 a piece & have gone two seasons so far. Hold a solid charge all winter w/ no maintainence. I'll buy another set when these go.
