I know there are other threads on the topic, but I thought I would share my experience separately so it does not get lost in another's thread.
Background: 2013 Tesla Model S 85, 127k mi. Original battery as far as I am aware (1014114-00-B, T13A0004404 [Jan 2013?])
90kWh: $17,000 (HV bat) + ~$900 (ancillary parts, mostly suspension for the 'upgrade') + $429 (labor) +tax =~$20k
It seems I was provided the 90 kWh and from what I can see it is not software limiting. Range and SC charging rates are much improved. All around extremely happy with the service provided, the communication I received, and with the car, despite the hefty price tag on this repair. As I understand it, this is effectively the newest tech for the S batteries, I expect it to last significantly longer than the original.

- Nov 19: BMS_u029 error message after supercharge to 90%+
- Vehicle seems to not charge
- "Maximum battery charge level reduced"
- "OK to drive - Schedule service"
- Nov 23: Scheduled service/diagnostic
- Requested diagnostic first
- Wanted to know if terminal battery failure or if could possibly be something else
- If battery needed:
- What options available? 85/90/100kWh? New vs reman? Costs?
- Lead-times for battery packs?
- Expected turnaround/labor times?
- Loaner availability?
- Appt set for Nov 26th
- Requested diagnostic first
- Nov 26: Service appointment
- Was advised that diagnostic was done remotely, new HV battery needed
- Was given options of 85 or 90 kWh replacement packs
- Confirmed either choice would be reman pack, would come with 4y 50k mi warranty
90kWh: $17,000 (HV bat) + ~$900 (ancillary parts, mostly suspension for the 'upgrade') + $429 (labor) +tax =~$20k
- Service Center advisor informed that if 90 chosen, the cost would be as outlined above ~$20k. If 85 chosen, price would be the ~$15k above
- HOWEVER: Tesla can provide the 90 in lieu of the 85 (if they choose, pending availability or other reasons). If this were to occur, the 'ancillary' costs above would be waived.
- If the 90 is installed in place of the 85, the 5 differential can be software unlocked for $750
- HOWEVER: Tesla can provide the 90 in lieu of the 85 (if they choose, pending availability or other reasons). If this were to occur, the 'ancillary' costs above would be waived.
- Was advised that a battery would take 2-3 weeks to arrive, and that the battery could not be ordered unless drop car off and sign service agreement.
- Was offered a loaner (likely M3), but would not be available until Monday (this was on a Saturday)
- Service Center advisor informed that if 90 chosen, the cost would be as outlined above ~$20k. If 85 chosen, price would be the ~$15k above
- Nov 28: Service Center
- Chose to have replacement 85 kWh battery (
for 90) @ ~$15k - Was anticipating loaner, but I asked if we could instead let me continue to drive my car until the replacement arrived
- I chose to pursue if it were possible to retain my car instead of take a loaner for the time waiting on the replacement HV battery arrival. Was initially told this is not possible but upon further review was allowed to do this. I am out of warranty, I did not feel comfortable taking advantage of a free loaner for 3 weeks. The car was still charging to ~90 miles, I could make do for this time.
- Via app messaging: was advised that the battery was ordered and they would contact me when arrived in order to arrange replacement
- Chose to have replacement 85 kWh battery (
- Dec 5: Advised ETA of HV battery, Dec 15
- Was periodically updated, ETA changed to Dec 16
- Dec 16 (fri): Advised HV battery arrived, loaner available
- Arranged to come in same-day to drop off car and pick up loaner ('22 MY perf.)
- Dec 17 (sat): Advised vehicle ready for pickup
- Invoice showed ~$17k (was supposed to be ~$15k), had a few suspension items on it that should not have been
- My service advisor was unavailable (weekend), decided to keep loaner until Monday when he was back in the office
- Invoice showed ~$17k (was supposed to be ~$15k), had a few suspension items on it that should not have been
- Dec 19 (mon): Corrected invoice was provided, first thing in the morning
- $13,250 HV battery (ASY-HV BATTERY,SX-SW LIM 85(1918190-85-A)) + $25.92 (battery bolts) + $429 (labor) + $1028.89 (tax) = $14,733.81 total
- Paid and picked up
- Pre-repair:
- Rated (not ideal) range @ 100% = ~228mi (of 265mi when new, ~14% degradation)
- Rough supercharging rate was something like SoC + kW = 100 to 105
- Example @ 25% SoC I would see ~ 80kW
- Post-repair:
- Rated range @ 100% = 298mi (via Teslafi)
- I have only charged 3 times (to 80%) since the repair, but the range estimated range has actually slightly increased from 296 to 298 over this time.
- Rough supercharging rate: SoC + kW = 130 to 140, and maintains higher kW much deeper into the curve
- Rated range @ 100% = 298mi (via Teslafi)
