I have never ran them. I fish mainly every other weekend. But my question is do these really hold up more long term than standard batteries? For instance let’s just say a pro didn’t sell their boat every year. How long would they keep them on their boat or what is their lifespan. In general of course. I know usage and charge habits have a lot to do with it. Mainly what’s best on a budget. I know what I can afford but I don’t want to have to afford batteries every year. Thanks y’all!
