Bowtech_archer07 Posted June 18, 2007 Report Share Posted June 18, 2007 Hey everyone. My dad and I are looking to buy a 12 volt. deep cycle battery and we were wondering what to look for?? Cold Cranking Amps like on a car battery or what. Also what brands are the best. Any advice will be greatly appreciated Thanks! Quote Link to comment Share on other sites More sharing options...
LifeNRA Posted June 18, 2007 Report Share Posted June 18, 2007 What are you needing it for? Trolling motor only? Trolling motor and accessories? If you will be using it on lakes that only allow electric motors you will want to buy the biggest one you can! I use an Interstate SRM-29, the the biggest one they make I believe is a SRM-31. Just make sure that you will need a 12 or 24 volt system. Quote Link to comment Share on other sites More sharing options...
Hoyt03 Posted June 18, 2007 Report Share Posted June 18, 2007 Walmart sells a good marine battery cheaper then the rest by like 30 or so dollars. I have 3 of them. 2 in my bass boat to run my 24 volt trolling motor, the other one runs my 12 volt trolling motor for the back of my boat when fishing bigger electric only lakes I run two at the same time. If you need a cranking battery that is a different battery then for trolling motors. I can get you the exact model if you want, don't feel like running downstairs right this second.

Texan_Til_I_Die Posted June 19, 2007 Report Share Posted June 19, 2007 What you really need to compare is the Reserve Capacity of the deep cycle batteries. Reserve capacity is the number of minutes a battery can maintain a useful voltage under a 25 ampere discharge. The higher the minute rating, the greater the battery's ability to run lights, pumps, trolling motors, and electronics for a longer period before recharging is necessary. The 25 Amp Reserve Capacity Rating is more realistic than Amp-Hour or CCA as a measurement of capacity for deep cycle service. Batteries with high Cold Cranking Ratings are easy and inexpensive to build, however their Reserve Capacity, Cycle Life (the number of discharges and charges the battery can deliver) and Service life are poor. Reserve Capacity is difficult and costly to engineer into a battery and requires higher quality cell materials, so expect to pay more for batteries with higher Reserve Capacities.
