I agree, 210mAh doesn't seem enough to drain a car battery in a day. The original battery went very dead after I didn't use the car for several weeks. I left a Bluetooth GPS receiver plugged in (oops). After that the battery was never the same and seemed to have problems starting the car. I eventually replaced the battery before an extended trip in Ottawa.

Well I was going to go today and get the battery tested but my car wouldn't start. With the battery disconnected for about 24 hours, the voltage dropped from 12.5V to about 11.7V. Sounds like the battery is toast. Once I get more time (damn work pager won't stop), I will take the battery into Crappy Tire for a test.

I wasn't paying attention to the rpm when I measured the 14.5V, but the engine was cold and had just started - probably spinning about 1,100rpm. Once I swap the battery, I will definitely check the voltage again with the engine reving a bit in case the voltage regulator is a problem.

Thanks so much for the replies.
