The last time I bought a new battery it was a standard car battery and I never felt comfortable with it. This year I will go with a marine battery but what type. Cold crank or deep start? We normally just take it to our pond. But occasionally we will head out on an open body of water, hang around a local sand bar and play some tunes. I always worry that it won't start. Never happened but always a first time. Then there is the problem of the battery well being so shallow. So, any recommendations from you folks in the know? Thanks in advance.
