BTW, if you do this while the battery is in the car and connected, and you get a less than satisfactory result, there's no guarantee you don't have some sort of parasitic current drain. If the result is good, you're good. But if it's bad, you might want to repeat the test with the battery disconnected just to be sure you're not condemning a good, (and expensive,) battery.
