I had the same trouble a few years ago. Not I use Opti's
Decoy dude Im the battery pro when it comes to trolling motor batts....I have done tons of research on what to use.....I use Lifelines, they were recommened to me by that **** RangerZ520(chad) and Basslady...they both know thier stuff....but thier is a cheaper alternative....
The Sears DieHard Platinum Marine Group 31's are awesome as well....many will say you dont need to spend that much on a batt, w/ with 3 a 4 year free replacement who cares....let them go to Walmart every 6 months....I dont have the time...

Dude Optimas suck ass......not enough capacity....Go with the optima's. If the ones Franklin is recommending are spiral cell, give them a try. But you just can't go wrong with optima batteries. I have a yellow top that is around 5 yrs old, and still a solid reliable battery.
Good choice dude.....you wont be sorry....FYI heres the exact same battery, you could be paying $300Thanks for the input guys, and thanks Franklin for the post on the Sears Platinum series. I'm going to bite the bullet tomorrow for those. I hope they will be worth the money and will last more than a year.
