lifeline starting batteries for sale

So i was wondering why my trolling motor wasn’t lasting as long as it use to. Took these out to take to Batteries Plus and realized that the dealership installed Starting Batteries instead of deep-cell batteries for my trolling motor.

I don’t think they are damaged by using them as trolling motor batteries but if they are I’m sure somebody on here will let me/everyone know. They are about 18 months old. Model number GPL-1400T

I don’t want them to go to waste but i (**() sure wasn’t going to give them to batteries plus for their core charge. Retail is $190.00, make an offer. I need to show the wife I recouped some of the money I just spent on 2 new batteries!! :smiley:
