"your car better be tuned up and start on the first try"

Ping to the top. Car batteries have TWO important ratings: Cold Cranking Amps (CCA) and also Reserve Capacity (RC) which relates to the total energy the battery will deliver. This "battery" may be able to deliver the CCA necessary for a single start, but will have a tiny fraction of the RC stored in a conventional lead acid battery.

Additionally, I live in the cold Midwest, and get seven to ten years on my car batteries, not the three years stated in the article. I consider a three year old battery "new". This may not be true in desert climates, but is sure the case for a large majority of the country.

Agree entirely. I've never heard of a battery being dead after 3 years.
