Re: How long does it take to charge a trolling motor battery??
Hey RTD, It all depends on how far down the batt has been discharged, how large the batt is ie, reserve capacity, and what the output of your batt charger is. A 6 to 10 amp charger with auto shutoff and trickle charge is best on most deep cycle batts. If the batt is in good shape, the charger indicator will go to zero and thats when a trickle charge will float the batt. If it is not in good shape, the charger will stay somewhere above zero, say 1,2 or 3amps. this indicates sulfation of the plates and the battery is on the way out. hope this is helpful. T
