Location: New Brighton, MN | How many people out there use the systems (can't remember what it's called) that use the alternator in your motor to charge your cranking battery and your trolling motor battery simultaneously? I saw the unit for $100 at Gander, but not sure if it's worth it. It would be pretty slick to re-charge the battery a bit every time I change spots, or troll for a few hours. But does it charge fast enough? is it worth the cash?

Location: The Sportsman, home, or out on the water | I do not have one, but here is my take on this.........
Deep cycle batteries are engineered to sustain a long, slow draw, and to sustain a long, slow recharge. By forcing a quick charge on a deep cycle (from an altenator for instance) I feel that either:
1) the deepcycles wont take the charge fast enough to make it worth it or
2) it will accecpt the charge and comprimse the battery, shortening its life.
I'm no rocket scientist. Maybe there is someone in the battery industry that can shed more light. | |
