Mine runs about 13.5-13.7 also, and I've had no issues with it dying or being hard to crank, even with the temps being in the single digits lately. I have a 2001.

That voltage range is normal for the Catera. How did you check for the voltage, is it directly from the alternator or from the battery cables that connect to the battery? The reason i asked is because, i had this problem of a dying battery and the culprit is a low voltage coming from the alternator. But i only made the check from the battery cables connected to the battery. Then I remembered about replacing the cables if you notice discoloration. And voila, after just replacing the positive battery cable, the voltage went back up to around 13.5-14. And no more dying battery.
