Trolling Motor Battery

I have a 36 volt Motor Guide and one of the batteries went out. I bought a Duralast marine dual purpose battery that exceeds the other ones. Is this the type of battery that I want or should I get just a trolling motor battery. The other 2 are 100%. Thanks Ryan.

For the best results, you should never mix sizes or types of batteries in a bank of batteries, and they should all be the same age, ie, 1 new, get all new.
