I just paid $106 (total) for my trolling motor battery (Interstate). The last one lasted me 5 years. My search came up with: The Exide ($82)brand came with a 12 month warranty, I think the Interstate has a 30 month warranty, the auto parts people told me to NOT go with their brands (30 day to 4 month warranty), from NAPA and O'Riliey. Good luck with your search.
