Group 27 RV/Marine cranking battery, from Costco, Sam's, Walmart, or a discount auto parts - about $60.
Johnson Controls is one of the largest manufacturers of batteries in the country and they are marketed under many trade names, many of which are found at these retailers. Interstate and Diehard are also good. There are good batteries from marine stores however you'll pay a lot more for them. Believe it or not, what one would think are 'crap' batteries from Walmart are actually pretty good.

Here's a thread where we discussed batteries, and there are others if you search:

Here's a good explanation of battery history, terms, types, and applications:

I always look at replacement between the 3rd and 4th year. Why? Because I've seen degradation beginning then, particularly faster discharging. This is my guideline for a properly maintained battery. Poorly maintained batteries can be lost a lot sooner.

My Marlin came with Deka batteries, GP27.

In searching for replacements I came across Interstate SRM-27B Deep Cycle/Cranking. They have the GP27 physical size but pack more punch and reserve. Don't confuse with the SRM-27 - not the same batteries. The B series is generally not carried by distributors and must be spacial ordered. They are horses and will run your electronics for a long time with plenty of startup power for the run home.
