Our Model X is great car and we love it.( except fo a few things that get fix and come back again with the same problem). My question is about the range of the car and how to check battery degradation.
I was by SC that charging the car in a supercharger everyday or every other day is not a good practice because the way the supercharger work.
SC told me not to charge the car when the battery is over 50%
I am reading here that keeping the car on the charge is the best option. Until I read this forums I was not charging the car everyday but keep the maximum charge to 80%. When I check millages the car give us with a full charge battery 252 max rather than 289 when it was new or the 309 that was rated Milleage.
There is anyway to check the health of the battery and is the car is plug in everyday the only thing to avoid is to lower the battery to under 20%
