Are all 90kWh batteries alike?

[Tyler Durden]

I am considering purchasing a Model S P85D that had it's Battery and Motors replaced under warranty last year (Sep 2022).
Is it possible that the new battery is the latest chemistry or is it likely to be a reconditioned unit?
What about the motors? Have they changed over the years?

I had a 2012 P85 that got rebranded as a P90

There were different 90 kwh batteries and the earlier ones had a higher silicone doping that made them susceptible to degradation but they somewhat solved it in a subsequent version of the 90 battery.. also the drive units in the very early years pretty much all got changed out to a better version (long story short).. what year are you looking at?

It's a 2015 P85D. The display and app still show P85D.

Hmm that's weird.. ask for the service record... It's probably a good deal though . Battery still under warranty then?

 

[Tyler Durden]

The service record is difficult to come by. Apparently the seller is having to wait for Tesla to release the details as the work was carried out before he took ownership.

Also, the seller says the battery and motors are only under warranty until the standard 8 years are up. So September 2023 in this case.

How does he know it was even replaced then??

 

[Tyler Durden]

I guess the previous owner told him. He also said, " I took the car to Tesla Glasgow and the guy done a check and told me the batteries and motors were swapped for new. I also have the Tesla app and Tessie app both confirm battery is 96% efficient and charge rate on a supercharger is 114kw ph you won't get that with a car that has deterioration."

He shared this screenshot with me.

Ask for a photo of the battery serial number

Your Tesla battery pack information is found on a sticker affixed to the front right side of the battery pack that can be seen when looking under your car from just behind the front right (passenger side) wheel

Decoding Your Tesla Battery Pack Version

Is there a difference between the Tesla A battery pack from the B pack? A Tesla battery pack label/sticker is affixed to the front right side of the battery pack.

This thread has information on some of the different pack part numbers for new replacement packs and remanufactured packs. The part number is on the same sticker as the serial number, visible behind the right front wheel (driver's side in the UK).

My 2013 P85+ got the infamous bms_u029 "Charge level reduced" last week and after reading up on the forum and going back and forth with Tesla Service I decided to write up what I learned. Much of this info is available on this forum but buried in various threads. My hope is to make this post...

Here it is. A 1014116-00-C.

Is there a way to see what motors are fitted too?

That’s the one you want. That was a brand new battery whenever it was replaced. It was manufactured sometime in 2022.

Not without pulling panels and such.

The front motor is typically very reliable and failures are rare.

The rear motor has undergone several revisions to address some design flaws in earlier versions. Replacements are almost always remanufactured but generally whatever the latest internal revision was at the time of replacement so in general a replacement is a good thing.

Depending on what you can get it for, could be a very good deal with that battery.

 

[Tyler Durden]

Thanks for your input. Very useful.

That battery was made in Sept 2022 and it's a new battery, not refurbished.

On a side note, my 2015 P85D's label says I'm running on 400VDC instead of 350? Anything I should be aware of? My battery is the original.

Originally produced 85/90 kWh batteries were all 400v - 16x 25 volt modules in series.

The “new” 85/90kwh pack that was first produced in 2021 is 350v - 14x 25 volt modules in series (but each module has more cells packed into it).

I got the same for my 2015 p90dl under warranty. Brand new... suc speed is peak 115kw and stays about 100kw on 50%.
Range is 438km on 100%

Here is the current situation from a charger...
If you have a 85, you might unlock the battery to give the 90kw (the pack is about 87kw usable) so its about 8 kw more usable than the original 85 pack.
I read somewhere Tesla is charging about 800 usd for this, which in mine opinion is a good buy.
