Electrical Wierdness.. Battery perhaps?
So the last couple of days my 04 CS has started doing some strange things.
1. When I insert the key, sometimes I have to pull it out and re insert it to get a response.
2. When I start the vehicle, I briefly see a Battery on the display and the words "Engine Start" . (never noticed this in the past year)
3. My AC seems to be tied to it somehow. Sometimes it'll be 5 minutes before the Blower/Condenser kick in. None of the controls seem to be working even though the display on the AC appears normal.
4. My sunroof would not "close". it would open all the way or the closed but lifted mode but wouldn't close normally. HOWEVER, when I activated the sunroof the AC turned on LOL
I have a feeling that one of both of the battery's are OEM so replacement may be in order. Any ideas on what to try to diagnose the problem? The car doesn't seem to have any trouble starting, just some general weirdness with the operation of a few things.
any good aftermarket battery options? Brand or model info would be much appreciated. Are the OEM batteries maintenance free? BTW my CS is an 04 with about 70k miles
thanks for any help or ideas!

It sure sounds like the battery. How is the cranking/starting performance? Is it slower than usual?
You may pull it out and take it to Autozone to get load tested. I think you will find it had reached end of life.
