Thanks for the info Beemerman.
I'm just trying to figure out which way to go. For the price of the dry cells, you could replace the lead acid batteries, twice.
I also wrecked my batteries last year. They don't take a full charge now.
I had a major malfunction on my big motor late last year (that's a whole other story in itself --- Hey? Where's all that oil coming from? Oil injected 2 stroke) and in an effort to get it started I basically cooked my batteries.
I have a cranking battery for starting the big motor and a deep cycle for running all the electronics, radio, stereo, downriggers, lights, spot light, etc. I troll with a 4 stroke Honda kicker which doesn't charge much of anything. While trolling I turn my battery switch to "1". When starting and running I have my switch on "both".
Anyways, these things will happen.
Fortunately I had a kicker. I ran in from 21 miles with the kicker motor. It took almost 4 hours.
