Re: Boat battery
I just saw this post. It's a topic about which I really do know something so I weigh in. It' always surprising to me when I read about battery failure after such short periods of time. As far as the wiring goes i defer to Capt Frank but as to the batteries themselves why do people insist on using wet cell batteries on boats? At the very least the trolling motor should be hooked up separately to a deep cycle AGM sized to fit. I don' t care how much more they cost. Wouldn't you rather make an investment than commit to. A series of payments? You just can't kill these things. Forget about battery tenders. I have a 55 AH that has sat in my unheated garage for two years and still shows a full charge. I picked up two 17AH's from a friend that were both reading slightly over 6 volts. I wired them in parallel and put them on a 2 amp charge. It took 36 hours but I used them without incident for months until I sold them along with a boat.
Optima's aren't the only choice. Try Batterymart.com.
