I have a November 2014 S85 RWD with AutoPilot - currently at 120,000 KM. (about 75,000 miles)
A few weeks ago I got a very bad message saying : Battery Charge Level Will be Restricted... and I went right away to the Tesla center to be told that my battery needed to be replaced.
At first they told me that they no longer make 85KW and I would probably end up with a 90KW battery but it could be a few months before I get that battery - there was to be a silver lining in my grief.
However, one week later they call me and said they replaced my battery and my car was ready to be picked up. Sweet.
When I got there, my delight went from great to disappointed...
I got another battery alright - but an 85 - It's OK - I did not expect an upgrade to begin with, but I was hoping.
Then things went from good to "I am not sure this is right" ...
When I got my car brand new, my battery was giving me 424 KM of range when charged to 100% (rated of course). After almost four years, I had some degradation, I was expecting that and before the problem occured, It was charging at 100% to 417 KM - not bad after almost four years - lost only 7 KM of range in that time.
The new battery charged to 395 KM at 100%... Now I am not so happy anymore. A "new" battery would not suppose to charge to the level my new car was charging at? That is what I would expect, but it is the other way around... this battery charge way less than my previous old battery... not happy.
So I ask the service dept why it is so: answer: You have to break in the battery - charge and discharge at different levels for about 4-6 weeks and it should charge back to where it should... hummm. I am not so sure that will work - but I will give it a go.
Anyone else here has had this issue? What were your results - were you able to get the charge to an almost new battery level?
For reference - here is the part # for my replacement battery - ASY, HV BATT, S3, BB, REMAN, MDLS (1088815-01-B) - I know this is a refurbished battery not new - any other info I can get from that part #?
