Battery replacement 11/15 P90D

[tesluv108]

My 2015 P90PL, has 204,000 klms (126,000 miles) on V1 battery. It's never failed.

You've prompted me to do 100% charge and check 'rated range'.

Will share when I get result.

How often have you supercharged? Looking forward to your results and others!

Ok, so using the 'rated' setting as it's the only constant really that I know of for comparison
100% Rated capacity in 2016 = 502 klm (312 miles) - not sure what the odometer was then
100% Rated Capacity in 2023 = 447 klm (277 miles) - 204, 000 klms (126,000 miles)

I predominantly used at home charging (32 Amp single phase) until 2022. To that point I estimate I supercharged less than 30 times.
Since 2022, when the energy company ceased incentives for EV's, I now use SC 85% of the time. Twice weekly.
This may have increased the degradation, but I haven't charted it.
However, losing about 60klms/47miles in 'rated' range I think is completely fine considering the total mileage and age of the vehicle.

Has anyone got a battery replaced due to limited range? My 90d has continued to drop...now getting 256/294 at 100% charge with 55k miles on the car. That is 13% degradation in 3 years.

Actually that is reasonable. Originally the S90D was rated at 268 and then was bumped up to 290. My s90D is a pre-facelift. I purchased it at 70K miles and have monitored the battery with TeslaFi since I purchased the car. In that time of seen basically no degradation and the car has been holding 258-259 rated miles at 125k miles

My personal thoughts when someone says the 90 pack is prone to degradation, is that Tesla’s over enthusiastic rating for 290 on a battery that is pretty much an 85 battery with different chemistry.as I have not owned from new I’m not familiar, but did you ever see 290 rated?
