We bought our Mariah bowrider in 2011 with a single battery (wet battery). In 2012, we went with a dual battery setup and had two AGM batteries installed. Can't remember the size, but I think we went large.

Never had a problem with no use over a period of two weeks or so. Always put the battery switch to off. Bilge pump was direct wired to batteries. Over the winter, we changed the batteries before putting the boat to bed. Disconnected the batteries. In the spring, the batteries had enough power to crank up the engine with the "ear muffs" on.
