I did battery research while working at MSD Ignition years ago. We were trying to find a car battery (or helicopter, or other mil-spec application unit) that could withstand the G-forces from a dragster launch. Never did. I killed a bunch of expensive military spec and general consumer-grade batteries on that little sojourn. There is a reason you see MSD Magnetos on dragsters and not a battery powered ignition.
There were only a couple of places in the U.S.,even then, that built batteries and Johnson Controls was the main one. Gates was another, but IIRC they licensed/sold their "wrapped" battery design to Optima.
I've been buying Interstate batteries since then -- it is a generalization to say that most consumer auto batteries are about the same underneath their branded top caps -- but not far off. Buy the correct CCA for your vehicle, then price, and don't worry so much about the brand and its marketing.
