Batteries

What are some descent batteries for my 24v trolling motor, don't want to spend a fortune, I have some federated marine batteries on my boat now, I got last year about this time and one of them went out on me on the lake Any help would sure be appreciated.

Batteries plus - Duracell ultra AGM deepcycle. Good price, order online and pickup at store to get them 10% off.

If you have a Sam's card you can get them even cheaper, but less warranty.
