I'm sure there are multiple factors contributing to this answer, but on average how long should a fully charged trolling motor battery last with moderate to constant use? I have a used boat and just put in a new trolling motor battery - I have no idea how much performance I should expect to get.

A typical day for me is 6 to 8 hrs on the water with the trolling motor running moderately to constantly at slow speeds. (Just to keep the boat moving for slow drifts - musky or bass fishing).

Thanks in advance! Big Show
