I have no problem getting 5-7 years out of my regular batteries so from a cost standpoint it doesn’t make sense for me. I also get deals on regular batteries so for me that sweetens the pot. I am not doubting any companies, especially sponsors here but I will be curious down the road to see how they hold up to the 10 year warranties. For where I live, how I fish and how well regular batteries last there just isn’t a need. If I lived down south or tournament fished maybe I would. They sure aren’t cheap tho. (The “good” ones at least).
