I suspect electrical issues with the car, or maybe you have an uncommon battery size and are getting old stock batteries.
As many have stated there are basically 3 manufacturers of lead acid car batteries that are common in the US - Johnson Controls, East Penn/Deka, and Exide. Of the 3, Exide seems to have the worst reputation here and on other forums. Not sure if that is due to actual manufacturing issues, problems with their distribution and retail channels, or a few bad experiences from a minority of customers that get repeated over time.. Johnson Controls and East Penn both have great reputations.
As for AAA batteries, they're one of the 3. They may have different suppliers in different regions. I wouldn't normally buy one because better deals can be found without a ton of effort. However, sometimes convenience is worth the cost, and that's the entire point of the batteries stocked by AAA.
