I had my KW902 dongle on all day while the car was sitting. The voltage of the 12V battery was 11.7 V (according to LEAFSpy and confirmed with a multimeter). I put the car in drive mode, and after 10-15 minutes, the voltage was up to 14.4 V (confirmed with multimeter).
1. Do you think it would have stayed higher if I hadn't left the dongle on?
2. I had assumed that the dongle wouldn't draw enough current to be a problem. Was that a bad assumption?
3. At what voltage level might the low battery cause problems?
4. I'm surprised that it could charge up to 14.4 V so quickly. Is that possible?
Thanks.
