New battery = climate control problem





I hardly drive my car, so I can't say 100% that this is a new problem, but I think it is.
For anyone looking for a replacement battery....
I bought a Bosch at Pep Boys almost 3 years ago, basically because my car did outside their store and it was New Year's Day

The battery came with a 3 year free replacement warranty, and that came in handy. That battery died yesterday at the 34 month mark (2 months left on free replacement) and they gave me a new one.
My original AC Delco battery lasted 7 years, always on a battery maintainer. This one was also on a Ctek 800 maintainer, but died anyway.
I'm not sure if the battery is crap or my maintainer has a problem. I does light green to show full charge. I am thinking about replacing it with a Battery Tender Plus, but don't want to spend money if I don't have to.
Your comments are welcome.
