Battery Imbalance after 8 years

[emil.aguinaldo]

I'm curious what the voltage difference that is considered an imbalance? I have a 2014 P85+ with 90k miles and my average cell difference is .005v.

Hoping someone who knows can chime in. Looks like your getting close to the 8 year mark on your battery.

My warranty expires in March, but I'm hoping my battery will last for several more years.

Hope urs too. I had high hopes driving the car till battery degradation drives it down 5 miles full charge. Wasnt expecting to pay for a battery replacement worth tens of thousands.

I think the 057 company is 6k or so for a 85 or 90lw.

Another cell imbalance question. My cell difference is .006v which seems good to me.
The range says low 3.882 and high 3.888. Only 1 cell is 3.882, 2 cells are 3.889 so don't know why it says max is 3.888. And the majority of them are 3.888.
With only one cell (cell# 95) being 3.882, none are 3.883, only 3 are 3.884, does that mean that cell# 95 may fail down the road ?

Hi All,

Been an owner since 2013 of a model S85. Really love this car, had an early charging issue, liftgate replaced, side mirror replacement and experienced the touchscreen glue issue (upgraded Dash and touchscreen, now have caraoke). Ive been planning on just using this car until the motor conks out or battery degrades to zero.

Unfortunately, just a few days ago, just 3 months after my 8th year, i received an MCU_w029 error. After arranging for service, technician said its a battery imbalance and the quote is 20-25K to replace a battery of a 2013 model s85 (83K miles). From 235 miles full charge down to 119miles.

I dont think it makes sense to spend that money on replacing the battery compared to resale value (a year ago, tesla said 16K trade-in). Im looking for alternative fixes.

Worst thing about this is that if i bought a model x (was planning on buying one prior to this issue), i will still have raffle tickets for another battery imbalance draw after 8 years, making me unsure if i should continue buying tesla.

Curious to see how owners feel about the battery imbalance issue, especially those with cars 2012- 2013.

@emil.aguinaldo - So, what did you end up doing?

@emil.aguinaldo - So, what did you end up doing?

I talked to @wk057 team and also reached out to Tesla for a diagnostic, to get a close enough quote. They said they need to run diagnostic and check for compatibility, see if i can get the price down with a reman. Anyway, im gonna wait on the final estimate before deciding which way to go. Im scheduled to come in on december

Don't think so. I would recommend this thread below.

Service says $22k for new battery on 2012 Model S

I got my Model S VIN 1751 off the line back in 2012 and have had it ever since. On Feb 14th during the day, I pulled it out of the garage with 114 miles showing on the battery. I woke up in the morning with some battery low errors. When I got into the car, it told me that the car wouldn't drive...

So if your car is in perfect shape after 8-10 yrs and you like it..wouldnt an investment into a new battery pack be worth it? At 10-25k? I mean you could take that $$ and buy into a new tesla but you will spend alot more...
I wonder if in the next 5-10 yrs if you will be able to even get replacement battery packs?? for your "older tech" batteries? Or will they use the new battery tech to make a cpompatible pack if you own a 75/85/100 older car? Or will even a 100 be able to work in a 75 car? I mean there are alot of questions.

Definitely looking to keeping it. Last i asked Tesla they will only do a battery of the same capacity.

if in 10 yrs they still have/make 75 batteries i guess.

A 100 isn’t Crash tested with the standard suspension. The battery is too heavy. But Tesla and third parties have been known to put 100s in air suspension 75Ds. I don’t know that Tesla ever software locks those back to 75 as there wasn’t a factory 100 locked to 75.

…if in 10 yrs they still have/make 75 batteries i guess.

I doubt they make 75kWh S/X batteries anymore. If they make 14 module S/X packs at all they will be the new 85s. Tesla typically software locks them down to 75 since that was a factory configuration.

But I can’t imagine Tesla will keep that battery line open long even if it is still running since the new S/X don’t use the old modules and packs. It would be interesting to know their strategy for warranty replacements.

Which app is this? How to get this data?

Just saw this now, sorry. Scan My Tesla app, OBD reader, and the adapter depending on what year car you have. It only takes about 2 minutes to install it. You pop out the cubby under the main screen and in there you'll see the plug that the adapter and reader plug into. I have mine hanging out about 4" on the side of the cubby cause once in a while I have to unplug the reader and plug it back in to work.

scan my tesla - Adapters

What did you end up doing? I just got the same error my battery just went down to 91 miles

 

[sparklehunt]

Any updates from folks who have gotten this issue?

 

[meomyo]

i was told in my 2017 75d that the 90 replacement battery is what they would swap in and then unlock the extra capability..

Tesla just replaced the HV battery in my 2013 P85+ with 308,402 miles on it. They installed a 90kw pack, new 12v battery, upgraded rear control arms and did a four wheel alignment for $15,500. When the car was new I got 265 miles of range. Now it gets 298 miles of range.

My new (in 2016) MS90D showed 299mile range the day I picked it up. You did ok I'd say.

Original pack? You sure got your money's worth if so.
