Ok, I've read up on boat batteries (now that mine ended up dead on me on the water today). The guy at Autozone said a deep cycle was best, so I bought one with approximately 875 cranking amps. The guy at the boat store had sold me a "starting battery", which had like 725 cranking amps. It went kaput after some 2 months and only my third time out on the boat. Autozone said it was because I have electric trim, radio, etc, that starting batteries aren't ideal for that. I just read online that deep cycle batteries weren't ideal to start a boat with. What do you guys use? Did I just get a lemon with the starting battery and that is what I should be using?
