Well, the battery might not be the problem after all. I got the battery exchanged because it was not holding a charge and had only 120 CCA showing. But driving home after putting in the 2nd battery, I saw the "Low Battery Voltage" warning appear in the screen. I really doubt that 2 batteries in a row are bad. I just took it to the dealer because I was fed up with trying to figure it out, but what could possibly be bad? I had the alternator checked and it was putting out around 13.14 volts. That's normal range, right?

yes it is normal range, however, your car should not be pulling "juice" from the battery while you are driving. that is the whole purpose of the alternator. if your battery is dying while you are driving, you definitely have a charging issue. if the alternator is putting out 13.14 volts, thats ok, but once its hooked up and in operation, that voltage may be a lot lower. <p>who checked the alternator for you?

Re: Charging Issues (Ognar)

I took it to Autozone to get it checked. Probably not the best place to go, but I figured I would get a ballpark figure to see if the alternator is functioning at all. I was shocked myself at why the battery voltage would drop while driving, but I did forget to mention that when I turned off the climate control and radio while driving, the voltage warning was gone. I'm sure it is the alternator that's bad.

it definitely sounds like the alternator can't keep up with the demand for current, hence the voltage drop...and furthermore your warning light.

Re: (gdill2)

Thank goodness for warranty work. Turns out the voltage regulator was faulty, and the dealer found my oil leak which was coming from the breather box (PCV?), and fixed my clunking suspension by replacing the swaybar endlinks. They even put an extra vent hose on the headlight to help prevent moisture build-up. Oh, and the rocker panel weatherstripping that kept falling off.<p>Kudos to Roger Beasley Volvo service center. <IMG NAME="icon" SRC="http://********************/smile/emthup.gif" BORDER="0">

Re: (Majisto)

Austin is a great store lots of experience there, and Jim Coyle is really a great guy-real helpful. I worked there from 2000-2004. Glad to hear nothing has changed as far as the way they do business. They should keep your S80 in top shape. I have some friends that work at Georgetown too, I hear it's not so bad.I moved to Dallas right as they were opening that store. Anyway best of luck to you- Cheers<br>Fred<br>

Most cars have more like 13.8 at the battery while the car is running with proper voltage regulation.
