Which battery manufacturer is about the best one going now? I am replacing 2 Interstates (series 24 / 800 cca-1000 mca) that came with the boat. They are well past their usable life spans.
From what I understand there are really on like 2 major battery manufacturers and Johnson Controls makes the vast majority. I've had great luck with DieHards which are apparently JCI batteries.
My neighbor does roadside service for AAA, and he tells me that he sees very few Interstate batteries that are dead before their 'time'. I would have no problem suggesting them to a friend....
I just buy a marine battery at autozone and no problems so far. Battery maintenance probably more important than the brand, keep it charged up, plenty of water, etc.
Well, this is a total opinion question. Like this vs. that. But I will add my $.02 to the pot. I only use Interstate batteries in everything right down to my garden tractor and zero turn mower.
I use Interstate and Continental Which ever I can get the best deal on at the time. Currently just put 2 new Conti's in my boat. a starter and a deep cycle. Took the 3 year old interstate out. Is acting as a reserve on a battery maintainer in the Garage. Tahoe has an interstate, Dodge and Buick have a Conti. No problems with either.
