Two weeks ago my meter also said 108; it's lowest ever. Yesterday after finishing a 100% charge it said 139. I turned off the car, unplugged the car from the charger but left the cord connected to the car. I turned on the car and the meter said 149. Turned off the car, disconnected the cord, started again and the reading was 139. There is a good reason why this meter is called the Guess-o-meter.JeroenE wrote:If you still have 120-140 in the winter time that is really good., in my opinion My meter said 108 at it's lowest while it said 148 in the summer at it's highest.
