Good battery for bad weather?

[Maarchk]

Hello people,
I live in so CAl. I know the weather isn't truly bad. But since i've moved my car from a happy garage to an outdoor street parking its had some issues. The head lights died like 2 months later and now the battery is fading fast. The weather changes from 80 to 30 every day cause i'm up in the mountains and it gets cold.
When my car lived in a garage i think it liked me better. but anyways, now the battery is starting to struggle and its 3 years old so i don't know but i don't think that its that old. maybe thats old for a battery? I'm not sure.
Wow, to make a long story short. I'm looking for a new battery that does ok with decent temperature changes. I'm open to pay whatever is reasonable but i wondered if people liked some batteries better than others.

Thank you,

Mr. Mark.

I've never really been able to find a good battery. Usually I'll start to like a brand like Sears or Interstate but then I'll be let down later on. I'm starting to think it's luck of the draw and I've been going with whatever has the best warrenty lately.

A while ago Interstate batteries had a very good reputation, but I think they're not as highly regarded as they once were. At this point, I'm not sure what battery "shines".

ACDelco batteries are the shizz - they have consistently outperformed and outlasted anything else I've ever used.

Cool. thanks. I'll probably swing by Pep Boys or some where and pick one up this evening.

Thanks for all the fast responses. :)
