I have noticed the hidden charging before. I don't see any charge bars but the battery level goes up. What I have experienced the last few days is very obvious charging. I am driving down the road, foot on the gas pedal and there are 3 or 4 bars on the charge side of the meter. The charge state of the battery seems to always be around 1/2. I have just started noticing it when it has been cold.

Thanks for the discussion. Anybody else experience either of these things?
