    Tesla Model S 2014 HV Battery issue

    Hi, I have a Model S 2014 P85+ Last Monday I was driving it near from my house in Guatemala, but the car suddenly stoped with the warning: “Unable to drive, supply voltage too low”… I thought that would be a 12V battery failure, so, on my own, I replaced it for a new one. Yesterday, after...

    2013 Model S died - options for sale?

    Parked my 2013 MS in a garage for 2 days - it was at 80 miles when I parked it but wouldn’t turn on at all when I returned to it after two days. Got it towed to a Tesla service center and they say it is the HV battery. I don’t want to spend $20k to replace it at this point and would rather sell...

    Measure the current capacity of the hv battery

    Hi, is there a any accurate way to measure the current capacity of a Tesla model 3. I read about charging to 100%, discharging it and do the math, but is there not a more accurate way to do this? If its not possibly on my own, is it possible to do a measurement in a workshop?

    Few weeks ago there was a link on Tesla Service to procedure, software and cable on how to read Model 3 (guess also Y) HV battery status directly from battery itself via low voltage communication port (one under read seat). Status was intended for 3rd parties who handled HV to know what they...

    Hv battery replacement

    Tesla is trying to say my hv battery needs to be replaced because of dead cells in the battery. I had no sudden battery degradation. Charging worked fine. I got error codes about the 12v and my car would not go into drive but my battery stayed full. They took it in and said the coolant pump and...
