You mentioned in the other thread that you have two Duralast Marine Batteries. Those are known as "dual-purpose" batteries that can be used for both starting and deep-cycle applications.

Some marine batteries are starting only.
Marine could mean that there is a larger space under the plates to catch shedding from the plates. In this context, marine means the battery can tolerate pounding or rough riding better without shorting out internally.
The two terms to look for on your dual-purpose battery are deep cycle or trolling along with a prominent display of AH or a label like DC27.
