My range is down to barely 150 miles out of 318. Tesla refuses to acknowledge pack is degrading. Its down to 60% efficiency now. Don't give a lecture on driving style. I have 230k on my S, it's been in over 30 states. The pack is going bad. I going on 5k trip this week. It should kill it.

Could you send us all a picture of the energy graph. Not the trips, but the energy graph. Sounds not good, but there is always an explanation.

Assuming what you say is true, then they need to replace the pack - they have no argument against it.

Understanding Battery Degradation

Battery degradation is a natural process that occurs over time. Tesla's warranty ensures that the battery will maintain at least 70% of its original capacity during the warranty period. If the capacity falls below this threshold, Tesla will repair or replace the battery pack at no cost to the owner.

It's important to note that Tesla assesses battery health using its own diagnostic tools. If you suspect significant degradation, it's advisable to schedule a service appointment for an official evaluation.


If you need assistance in checking your battery's health or have further questions about the warranty process, feel free to ask!

I have 43,615 miles on my dual motor. 100% charge is 312 miles. Was 318 new. I drive like hell and I currently have the winter tire package on the truck. It is always parked outside in upstate New York.

Think there may be something wrong with Tessie, every other Tesla I have owned has shown some battery degradation over 10k miles or so. CT still shows 100% battery health

My battery has the exact same range as when new 12 months and 24,800 miles. Grateful!

If that is true, then you can get a replacement if the range is in fact below 70%, calling BS, unless can you can screenshot your service requests?

They have a 2013 & 2017 S ... so it is not their first rodeo.
Still, it is hard to imagine what the Tesla service centers could be thinking or saying if the range is really that low. I'd run the battery test in the service menu.

Yeah I noticed he stated that as well. And he has posted around here, wonder if he was talking about "while towing a boat" as he recently posted --

I towed 7500 Florida to north Iowa and back, 3500 miles. Got a little over 150 mile range out of 300 charge. 70 mph with AC on. It cost 384 going up 375 coming back. My F350 would have cost twice.
It really tows the weight up hill great in mountains. Impressed.

Color me skeptical. Nickel-cobalt-manganese (NCM) cells will degrade overtime, even with low usage, its normal and expected. I feel that the BMS of these systems do not tell us the whole story. Here is an example for the F150 Lightning, its not Tesla, but its the same chemistry. The BMS reports (8:55 in the video) battery health of 100% after 3 years of use. Yet when they test it with a weeks worth of driving (11:50 in the video), they only get 80% of the range.

The point is, I don't believe you can trust the estimated range. Its been shown even new Teslas get less real world range that what the screen estimates.

9 months. 7600 mi. 1.4% degradation. 297.23 max range.

Here's my lifetime charging data. Quite literally 50% Superchargers, 50% Level 2.

Do you typically stick to the recommended 80% charge limit or do you go a bit higher?

On a side note, does charging consistently past the 80% recommended charge limit affect the warranty at all?

Got back from a 5,900mi road trip last night and took a peak at my battery health this morning.

My FS Cybertruck (VIN 16,795) has nearly 29,000 miles on the odometer after almost a year of ownership, and Tessie (the data app) is still tracking my high voltage pack at 100% original capacity. 123kWh.

The truck's nav shows 313mi of the factory 318mi EPA-rated range at 100% charge. Tessie agrees with 313mi at 100%. Thats somewhere between 0.0-1.5% degradation after almost a year. Wow!

The dip in the graph is from my winter tires. Apparently that messes with the calculations, but I'm using the OEM All-Terrains now.

Maybe the 4680 is better than expected, or perhaps this is an outlier?

My battery is showing all the signs of lasting for decades too. Between 0% and 0.5% degradation after more than a year of being parked out in the summer sun and winter snow and cold rains 7 days/week. I don't give my Tesla credentials to 3rd party apps, but at 50% charge it consistently reports 158-159 miles. That's 316-318 miles of the original 318 miles (with the All-Terrain tires).

I'm pretty confident in these numbers because I occasionally take the battery SOC down to single digits and up to over 90%, just to let the BMS recalibrate.

I've had the All-Terrain winter tires on for about 4,500 of the 7K+ miles and they consume about 10-12% more than the summer AT tires but I still get great range. I stopped charging to 80% because it has so much more range than I need, even in the winter. Now I just charge to between 60-70% unless I'm leaving on a long trip. About 20% of my miles are Supercharger miles, almost all of those were a trip to Reno and back.

I think people worry about battery health too much Tesla has the best battery thermal management and BMS in the industry (due to all the fleet data they have leveraged to get where they are). Laboratory data and accelerated aging is all well and good, but I'm pretty sure Tesla has been doing complex data analysis on the millions of cars they have on the road. That's enough data to parse out extreme use cases and determine best battery management practices for longevity in extreme conditions.

I do think Tesla conservatively estimated the range/battery capacity when they released the Cybertruck and data coming back from the field has allowed them to add a little back in as the battery goes through it's first year degradation (which is always the quickest degradation, absent adjustments to the calibration of the battery).

I have a 7+ year old Model 3 with over 70K miles and it still charges up to 306-307 miles of it's original 310 mile range. And it can still actually go that far (or further under favorable conditions) at 60-65 mph in the real world. A lot of people over-estimate how many miles they actually need, particularly since most of us are driving by multiple Superchargers whenever we drive for a couple hundred miles on the freeway and they top us up so quickly these days. I rarely Supercharge much beyond 15 minutes (and I'm almost always thankful for the short breaks in a long day of driving).

The conversation on range gets distorted by the loudest voices online, most of who seem to need to drive 1000 mile days on a regular basis and have to drive 75-80 mph while towing huge trailers across the continent. TThese people focus on what THEY need and tend to forget that most people NEVER need to do that. I base that on all the comments here that Cybertruck sales can never be strong unless they increase the range to a whopping 500 miles. But that ignores the data that shows most 1/2-ton pickups never tow anything, let alone a big trailer for a thousand miles.

If massive range were so important to the bulk of the pickup market, then why does the Cybertruck outsell trucks like the Silverado that have a 100 mile range advantage? Last year the Cybertruck outsold the Silverado by a 3 to 1 margin. And why did so many Silverado buyers not buy the model with the most range?

Great points!!! the desire for 500 miles of range is a bit crazy for most people. Driving 80mph while towing a boat will is not the EPA estimate.

I have a longish commute compared to most people about 50 miles each way, 315 miles of range on my CT is way more than usually needed, my Performance Y is down to about 255 miles and is plenty for most trips.

Now if I do take a trip my people's bladder are only good for about 120 minutes, so a 20 minute charging stop is only a few minutes longer than if using gas. Not to mention in a gas car a "rest area" toilet is never my passenger's first choice.

Here's Tessie's graph of the pack health as reported by the BMC:

The weird recent uptick is because I charged to 100% several times instead of my usual 50% (it was for the Cybertruck Rodeo, and I kept forgetting to change the charge limit back lol).

Do I think charging to 100% expanded my pack capacity? No, I think this gave the BMS an opportunity to recalibrate.

When the packs are assembled, they choose cells with very similar voltages for consistency. If you got a batch with a slightly higher voltage, then the pack may have started above the rated capacity and thus the BMS reports "zero degradation".

Yes we get proper winter here in Michigan, but I do not garage my truck. It is outside 24/7, all year round, plugged into a Level 2 charger.
