kickingfrog Posted May 21, 2016 Report Share Posted May 21, 2016 The current Ontario Out of Doors (June 2016) has a one page article with some tips on boat batteries. One paragraph mentioned that with the all the electronics on board many boat owners were switching to a deep cycle battery for the starter battery. They did mention that you should be careful with the "largest motors" and that you should consult your owners manual. I've always used a starter battery and not had an issue but I only have one sonar unit, one livewell and a bilge running on the starter battery. I was wondering what others thought about this?

NANUK Posted May 21, 2016 Report Share Posted May 21, 2016 The current Ontario Out of Doors (June 2016) has a one page article with some tips on boat batteries.

I've always used a starter battery and not had an issue but I only have one sonar unit, one livewell and a bilge running on the starter battery. I was wondering what others thought about this? I have the same setup, a 7" sonar/GPS combo and some lights if I am fishing when its dark, I never use the livewell and the bilge pump never comes on, my kicker motor keeps the starting battery topped up when I am trolling, I use a 1000 CCA marine starting battery. If I had too many gadgets, I would consider running 2 batteries in parallel. I do have a group 31 deepcycle battery for my elect trolling motor and always carry jumper cables just in case.

grimsbylander Posted May 21, 2016 Report Share Posted May 21, 2016 There's so many variables in play that it's impossible to create a single rule that works for everyone. If you're cranking over a 50hp outboard, run one graph, and use your livewells periodically, you can probably get away with either. If you have a 200hp+, multiple graphs and run aerators all day, you may want a more specialized hybrid battery or a high quality cranking battery; one that can take the constant drain and still crank a V6. I personally don't see the need to run 2 batteries in parallel. The technology in today's cranking batteries allow a tournament boat to run 2-3 12 inch screens, structure scan, and livewells all day and then crank a 250hp over to get back; in all temperatures.

Mister G Posted May 23, 2016 Report Share Posted May 23, 2016 My new boat with a E-TEC 90 HO came with a Deep Cycle battery that I thought was strange........it has 625 CCA and 120 minute reserve........works great so for but it's only one year old right now. Time will tell. BTW the 3 bank on-board battery charger is always plugged in when not fishing with the boat. Link to comment Share on other sites More sharing options...
Tybo Posted May 23, 2016 Report Share Posted May 23, 2016 Likely talking about agm deep cycle. Which can be used either way. Link to comment Share on other sites More sharing options...
ecmilley Posted May 24, 2016 Report Share Posted May 24, 2016 (edited) True DC battery's usually have a lower CCA. I use a dp27 to crank over my v6. Runs 2 graphs 3 pumps and a talon all day Believe my rating is 220cca and 200 min reserve Edited May 24, 2016 by ecmilley Link to comment Share on other sites More sharing options...
