Took Delivery on a CPO (Used) X75D a month ago. Love the car, still getting used to the whole charging routine and what and how I should be charging. From what I read and researched, charge nightly to 90% seems to be the consensus. Must I do this religiously? Some days my commutes are only 20-30 miles leaving about 75% -80% left. Seems kind of ridiculous charging 10%~?
The other thing I am noticing is that the car is showing about an 8% (198 miles at 90%) degradation on the battery. I kind of find this hard to believe since the car only has about 17K miles on it. I'm getting 8% degradation by calculating what 100% would be and comparing to the rated mileage you get from a new X75D.
Any suggestions? I've read might be calibration error? Is the fix for this still to take the battery down to low digit miles and charge to 100%? Looking for some experienced knowledge here.
