I can easily help with that one. I've used the Canadian Tire top of the line (the most starting amps) Marine Starting Battery for almost 10 years without a problem. I run all the electronics, including the live well from it and I leave the sonar and GPS on continuously. Although technically illegal, if I'm taking fish home to eat, I run the aerator in the live well until I'm home and that usually takes an hour or more. One tip with a starting battery...replace it immediately if you have a hint of problems. I've towed quite a few people who figure they will fix the problem by charging up the battery. Once they (battery)go they do not recover, even if almost new. I've gone less than 3 years with some.
