Both my downriggers are electric, so lately I've always gone with deep cycle batteries (commonly called Marine batteries). But truthfully, I've used automotive batteries many times for many years with no problems. The deep cycle batteries are really only good for applications where you really discharge the battery. (Like Downriggers, Reels and Trolling motors) Otherwise you'll do just as good with an Automotive (car) type of battery.

If God didn't have a purpose for us we wouldn't be here, so
Live simply, Love generously, Care deeply, Speak kindly.
(Leave the rest to God) 
Silence, in the face of evil, is itself evil. Not to speak is to speak, not to act is to act. God will not hold us guiltless.
