What you say makes sense. And I'm encouraged by the fact that my wife misunderstood my request not to drive the car until I was certain it didn't have a current leak, and drove it after it had charged for about 10 hours, and had no problems. This was on a short trip, on which she made several stops. So yes, I'll give it a good long charge, and then monitor the draw. Thanks.
