HV Battery died and got a replacement with a bigger battery...

[Laughing Hippo]

Hi all, wanted to get some feedbacks.
I just got my battery replaced for my 2016 Model X 75D.
While checking the invoice, it showed a 90kwh pack.
Asked the center and was told it was locked to 75 but if I paid CAD3,000 more I can use it fully.

I am inclined on not doing it since I do not need the range,
but seems I am carrying around more weight which I do not need.

Did anyone ever do this before?

since it is capped, you can charge up to 100 percent without worrying about harming the battery. If that range works for you, this is perfect

This is interesting. I have a 2017 MX 75D and I'm curious could you share what happened when your HV battery failed? Also how were you charging the car? Mainly superchargers or just slow chargers? Thanks!

That's interesting. I would have thought they would offer a 100 pack since they are more plentiful. I wonder if the 90 was offered proving they have more reconditioned 90 in stock.

90 is a nice upgrade from a 75. Even locked Tesla did you a solid.

$3,000 now, could get you more money in the future when you are selling your car.

Rarely used supercharger and charged to 80% most of the time. Kept getting all kinds of weird errors saying the car would not start.

The 90kWh pack was not a success for Tesla as, if I recall correctly, it had greater than normal capacity loss over time. Interesting that Tesla still has them available and is using them for battery replacements in lower capacity models.

It would be interesting to see what your new rated range is when you charge to 100% compared to your 100% rated range when your 75D was new.

It will also be interesting to see what happens if you set your charge level to 100% and repeatedly charge; will you still get the warning not to do that repeatedly even though in reality you aren’t actually charging to 100% of the true battery capacity?

the new batteries installed designated as 90kwh are the replacements for cars that had 70/75/85/90 batteries from the ol' days. The chemistry is based on the current 100 batteries - so no relationship to the much (appropriately) maligned 90 batteries from around 2015

Just curious, did the invoice show an actual price for the replacement battery? The $3000 figure suggests a price of $200/kwh if there is any logic in that assumption. Labour costs for unlocking would be minimal versus for actually replacing a battery. Is the warranty for the replacement battery limited to the standard 8 years from delivery date of vehicle (or some other date)?

under warranty so there is no price on the invoice. the CAD 3000 was from a word of mouth from one of their service center staff after doing some research on his computer, I am not 100% sure of this. I think I will pull the trigger for the upgrade. Once it is done, I will post a comment on how it went.

I am curious as well, but I was told by the staff at the service center to charge to 80% and treat it as a 75 battery.

It’s up to you to decide whether to spend the money for the range, as for weight difference, probably less than 100 lbs. If the range is good for you then no need to spend extra money, I am not convinced you will get 3k more when you resell it.

Thank you for that information, I was not aware of that. Good to hear! How did you find that out?

In that case, I would think that the OP could consistently charge his 75D to 100% without a problem. Though I expect the car and the app will display the message warning not to do so.

Definity good to hear that the chemistry is based on the current 100 batteries.

Careful, that's a guess. To be sure, check the part number / sticker on the battery pack. It is visible behind one of the wheels (Google it if you don't know where to look). If it says 350v then yes it is the new chemistry.

it is indeed 350v
