Where do they come up with this stuff?
I've lived in the 'red' area of this chart for the last 50 years and don't find this information to be anything like true (battery life 2-3 years). I've had a number of battery types on various vehicles over the years and can't remember any that didn't last 4-5 years.
Had an Optima Red Top on my '70 model Bronco for 9 (count 'em 9) years before it died. An Orbital on my 80 Series for almost 8 years. I've had single battery set ups, dual battery set ups, winches, Aux lights, etc....
Surely...I haven't just been 'lucky'?
I had a 1969 Jaguar XKE roadster when I was in college that was kinda hard on batteries, but I don't think the alternator was all that great on it. Other than that...my batteries last longer than suggested in this chart:
