AAA Battery Service Compliment - Premium price, but a great service.
My starter was lugging on a cold start, and I was pretty sure the battery was on its way out. After a few seconds of running, it would turn over OK, so I figured it wasn't the alternator.
Called the AAA for battery truck service. Tech showed up within 40 minutes, ran a check and indicated 'replace'. Within 10 minutes, new battery was in the vehicle, flying high. New battery was rated at 550 CCA and actually showed over 700 on the tech's digital testing unit.
The total cost for the service call and battery replacement was $111. Yes, I could get a battery cheaper at Autozone or Sears, but they don't show up on your doorstep in short order and have you on the road in 15 minutes. According to the guy that helped me, AAA has recently changed to Deka brand batteries ( http://www.eastpenn-deka.com/ ) which are highly reliable and made in the USA.
Hope this helps! I am in Central New Jersey, Mercer County.
