Just had two new Big Mommas installed. Came highly recommended by boat shop. I had never heard of them until then. Haven't had a chance to try them out yet, but I've noticed a lot of people talk about them here since the install. Seem to be always in everyones top 2-3 batteries available. They also have a Big something or other that is their cranking battery version.

My boat came with an Optima Blue Top for the main battery and two cheap Napa brand batteries for the trolling motor. Optima crapped out already and the Napa batteries are still going strong. I'm not fully against Optima yet, becuase it may be something in the wiring in my boat that caused the battery to screw up, but I'm also not sold that it's worth the price tag.
Most of the cheap batteries come out of the same plants. So you should decide based upon warranty and availability. As far as the expensive battered don't go optima they are not what they once were. Odysesy is one of the best, however sears diehard platinum are rebadged odysseys with an incredie warranty. I think it's either 7 or 8 years with something like 4 or 5 year replacement then prorate after.
Look carefully at the warranties. Not just the years total but how they handle. Replace vs prorate.
