I've had the stock Panasonic battery in my X since I bought it a little over 3 years ago and amazingly it is still working, but it's probably a good time to start looking for a replacement. I noticed last night that if I push two window buttons at the same time my idle drops a couple hundred rpm and the headlights dim a little

Any suggestions for a good battery? I just found the Odyssey PC680 and it looks pretty good. I drive my car every day and I don't have an amp or any subs and the coldest temperature I'll have to start in is probably 20 degrees and that would only be a few days a year.

 

If you are seeing this problem when the car is running I'dbe more worried about your alternator.

That said, a battery living 3 years in NM ... yeah you are right, you probably ARE due for a replacement. Then again trunk mounted batteries do a LOT better in the southwest heat.

 

DieHard Platinums are rebranded Odyssey batteries. Just FYI.
