Our Walmart sells Group 29 Deep cycle batteries, like the type you'd use to run a trolling motor. I've been using their "29DC" batteries for years. I have 2 mounted on my camper and use them for occasional boondocking without any problems. I have one that I bought in 2012 that I use for my trolling motor and it still holds a charge, even when it sits in the garage for months without being used. I do use a better quality charger to top them off when needed, maybe that's why I get good life out of them?
More likely because you do NOT discharge them below 80% SOC !
