[What type of storage battery is best suited] to run a trolling motor? A deep-cycle trolling or a deep-cycle starting battery? What is the difference [between deep-cylce and engine-cranking or engine-starting battteries]?

[I] am so pumped up. I have always wanted a [Boston Whaler boat] and finally bought a 15-footer. Mike in Summerfield, Florida

You want a deep cycle battery for a trolling motor.

Deep Cycle batteries can run down (deep cycled) more times
than a starting battery because they have thicker plates.

Starting batteries can put out more amps peak because they
have have thinner plates, therefore more surface area.

Typically a deep-cycle battery will be used to operate an electric trolling motor. Engine cranking batteries do not tolerate deep discharge, and often their lifespan will be shortened if they are subjected to a deep discharge.

Don't overlook the dual purpose, Deep Cycle/Starting, batteries, Mike.

I have used Wal Mart's Everstart Marine Maxx gp 27 (the BIG yellow one) for both purposes for years. Never had one fail or fail to take and hold a full charge.

There are entire websites dedicated just to batteries. You can explore this topic at great length. There are many types and sizes of batteries used in recreational boats. There does not seem to be one clear choice or preference.

Take a look at Cabelas dual purpose AGM cells. They also have excellent chargers. jsp?_DARGS=/cabelas/en/common/catalog/item-link.jsp_A& _DAV=MainCatcat21276-cat350007&id=0041060016446a&navCount=1& podId=0041060&parentId=cat350007&masterpathid=&navAction=push& catalogCode=QT&rid=&parentType=index&indexId=cat350007&hasJS=true jsp?_DARGS=/cabelas/en/common/catalog/pod-link.jsp_A& _DAV=MainCatcat21276-cat601333-cat600056_TGP&rid=&indexId=cat600056& navAction=push&masterpathid=&navCount=3&parentType=index& parentId=cat600056&id=0019015
