x2 - plus if you leave a cell/gps charger plugged in, they too will drain it overnight.

X3, an i-Pad charger will do the trick too.

All the batteries that will work in an HHR have roughly the same specs 600-660 cca, but very marginal "reserve time" which is the ability to provide juice for accessories and electrical loads with the engine off.

Thanks, nothing plugged in anywhere.

An update on this issue for me. 99% of the time I drive my HHR everyday and it starts with no hesitation. Several weeks ago, I did not start it for several days and when I tried it turned over very slowly and the Power Steering and Air Bag lights came on. I did not drive it yesterday and it was slow to turn over this morning, but no lights. This battery is less than 6 months old. Could it be bad? If I drive it over to AutoZone will they be able to determine if the battery is not right, since once it starts I seem to have plenty of juice? This generally would not be an issue since I drive daily, but I am concerned it will not start if I go on a trip and leave it at the airport for several days.
