I was thinking that my 12v batt was going out or something was causing a drain because for about a week now the main pack would not keep charged. Today on the way to work I was expecting an autostop but instead the car started charging. The pack went from about a third to nothing in a second flat, would not autostop and started charging. It seems to hold a charge better now after the "recal". Does all this sound right? How often you all have recals?
