Pro Batteries

I saw a banner at an auto shop for 'Acdelco Batteries'. The tag line for the brand is 'The Professional Battery' and I think that is just a horrible slogan. What car batteries are considered amateurs? All car batteries are professional by definition, you have to buy them, therefore they are being paid to do their job, which I guess is start and help run your car. Maybe they don't mean professional as compared to amateur, maybe it is more along the lines of 'the battery chosen by those who drive professionally.' I guess that would be race car drivers, truck drivers, and pizza delivery boys. That makes more sense and is a better selling point, but I still think it is really dumb.
