It's an engine starting battery with 800 cold cranking amps at 0°F as shown in specs. It's an AGM construction wich is advanced glass matt. These are sealed and you can't spill them. These ALSO work as a deep cycle battery.
The new batteries that are out are combo meal batteries as they are labeled for engine starting AND deep cycle. They indeed work well for doing both. HOWEVER, in the old days, if you deep discharged an engine starting battery on a regular basis, you would shorten the lifespan of the battery much quicker. These new batteries may not have that problem.
The battery I have in my new Columbus RV is a combo labeled battery by Interstate brand. It is not AGM either. I don't have an engine to start on the Columbus so I could not tell you if it works well for that or not. Works well for deep cycle however.
