- In this eye-opening video, we dive deep into the controversial topic of Tesla battery degradation. Using real-world data from a 3-year case study, we uncover the truth about how much battery capacity Tesla owners can expect to lose over time.
Whether you're a current Tesla owner or considering buying one, this video is essential viewing. Don't miss out on this honest and unbiased look at the truth about Tesla battery degradation.
ATTENTION! watch the full video before commenting this is a lie because you might end up saying the exact same thing as I do in the video! The thumbnail has a ? In it on purpose!
Model 3 LR AWD owner since march 2019. Average WH 260, I've lost about 22 miles over 5+ years
The degradation really isn't as bad as people think but unfortunately the majority of people will just read titles and then go on to say "I read that Tesla Batteries have a 36% degradation...." I am actually expecting Tesla fans to comment all up in arms without realizing I point out during the video that the degradation isn't as bad as most people think but you just watch.... comment section will be nuts and I did it on purpose lol
I also own an EV - a Tesla Model 3 Standard Range since November 2021 and I’ll be honest, I haven’t even thought about either battery degradation or range loss. I expected it to not live up to the EPA’s estimates (which are done on a Dyno, not on the road at normal speeds with wind, starting, stopping, etc) and it hasn’t. 🤷♂️ It’s still a great car and I like it, so I’m going to stick with it for a while!
@@WheezyLex that's great. Thanks for sharing and watching the video. I appreciate it.
@@Outsider.Reviews That`s called clickbait isn`t it?
@@robertlarder1907 yeah it's a clickbait thumbnail, I'm not going to deny it and I mentioned it in the video. It's hard to breakthrough in the TH-cam world lol
Tesla can't "inflate" EPA numbers. It is the EPA who provides the guidance for the tests and defines the estimated range, not Tesla.
OEMs are provided 3 different types of EPA numbers and DO choose which one or the 3 to advertise. Best case, likely case and conservative. Most OEMs chose the middle and some the conservative.
Do they test every single car? I mean the test vehicle might achieve that but owners don't seem able to.
@@rosstulloch8100 No unfortunately the EPA does not test all cars that go on the market. As a matter of fact, they more often take the word of the manufacturer and when complaints arise, they then investigate which is why Tesla was ordered on 2 occasions that I know of to lower their range estimates on their vehicles but traditionally speaking, they do like all other branches and take the easy way since they don't have the budget or manpower to test all vehicles.
And we ALL know that we can trust the corrupt government departments, right?
my 2017 Model x has 260k km on it and it lost less than 10%
That's what I'm talking about!
Hmm, how can I turn 2.5% into 36%? Oh I know!I are dumb.
Exactly why I made a video explaining it
dont remember the # but the guy whit the uber had arround that much degration whit 2 times fast charging per day
Don’t believe it, I lost less than 7% in three years on my model S.
Sounds about right. Maybe a bit higher than expected but like it says in the video, the average is a bit less than 2% a year
8 years or 100,000 miles, whichever comes first, with minimum 70% retention of Battery capacity over the warranty period. If the Tesla above lost 36% within the warranty period, 8 years or 100,000 miles, Tesla would have replaced it. Nearly all, meaning that it is very rare, that owners report large amounts of battery degradation. Reporting from owners have been relatively small amounts.
Watch the video my friend! This comment is addressing a topic that was answered more thoroughly in the video and the numbers were clarified.
Ya, my 2020 model S hasn't lost 10 percent yet, so....
So.... I'm right. Awesome thanks
On my forth Tesla. It seams like the initial range estimate is a lot better these days. My latest Tesla, Dual Motor Cybertruck, hits very close to the range estimate. Just took it on a 1200 mile road trip and the "buffer" I had to charge to was way less than my previous Teslas. Adding a 10% buffer when charging seams to be suffice. On my Model Y I used to add a 20% buffer and would arrive with 5%. Have 2400 miles on it so far and 0% degredation, but also have never charged it past 90% (normally 80%)
That's what I'm also hearing. They have lowered the range estimates and they are actually attainable which is good to hear!
Queue a thousand Tesla owners/worshipers disputing this claim. Truth is Tesla's are cheap, the batteries are cheap and the mileage claims are fictional. In Europe, on the WLTP scale, not a single manufacturer range claim is attainable under normal driving conditions - not one. Battery degredation is REAL and happens faster than most people think, especially with regular DC rapid charging.
There are a few exceptions to EPA estimates. GM with the ultium platforms usually beats EPA estimates and Ford usually comes pretty close. I think manufacturers are slowly learning that customers do not want to be lied to and things are getting better. As for Tesla, their batteries are quite decent but the build quality is inferior to others. They strive in motors, batteries and software.
At the normal you charge your EV at home and don't have to go to the gas station. Unless of course you have more than 100+ miles to work and can not get home without having to re-charge . But in practice you will really enjoy not having to spend time at the gas station. Most people that think it is a problem to recharge an EV are people that haven't tried to own one. 🙂 Less need for service, and half the cost of driving (even that we in DK have one of the highest electricity processes) We are on out third year with an EV and we will never go back to an ICE. And the degradation? Not noticed. Believe they are getting better at battery management.
100% Agree. I am getting an EV for certain on my next vehicle, it's just a matter of which one and since I get to drive a different one every week.... it makes it hard to choose lol. I was debating hybrid for a short time but after reviewing quite a few EVs.... it's night and day! The EV is the way to go for me! They drive so well, handle like a dream, acceleration galore and is very convenient as a daily driver but also, it breaks up road trips nicely and makes them less of a rush.
Our Tesla model y is 5 years old and we’ve lost less than 8%. titles like this mislead people and contribute to the false information. You address this in your talk but many won’t hear you out and just read your title.
And those that just read titles without watching don't really deserve the time of day. I'm glad your Tesla is performing the way this video depicts. It brings more credibility to the report when first hand experience like yours is brought to light. Thank you for watching the video and giving us this feedback. I take all kinds of feedback and evolve the channel with insight coming from viewers like you.
From 70 to 64 isn't a 6% degradation. It's an 8.57% degradation. (1 - 64/70) x 100 = 8.57
Thank you for pointing out the correct calculation!
Good news is all Tesla battery's come with an 8 year 70% warranty, so if this happened you get as free new battery
That's a great warranty policy from Tesla!
This is the thing with new tech... it's going to take some time to work out all the little details, especially when talking about the batteries. Still better than an ICE though!
Absolutely, new technology always comes with its challenges, but it's exciting to see the progress!
Funny, my 1999 Volkswagen jetta still averages 4.9L/100km with 400k kms on the original engine and transmission, and my 2008 Dodge Grand Caravan still averages 13.5L/100km with 300k kms on the original engine and transmission.
How much fuel economy did you lose in eight years?
According to epa estimates, I've lost near 0% of my vehicles range in 25 and 16 years respectively.
Loss in power, sure. My Volkswagen can barely get out of its own way (not that it ever could), but loss in economy. No.
I'd be willing to bet that a property maintained ICE vehicle losses less than 1% of its fuel economy "range" per year.
@@huntsbychainsaw5986 I've noticed a 0.5L/100km drop in 8 years. I am also spending $400 more/month in gas when compared to Electricity for an EV. In that $400 I factor the higher cost of insurance, tires and faster tire wear.
@@Outsider.Reviews Cost of ownership is a different debate but a loss of .5L/100km in 8 years is understandable. That being said, that is a loss of 0.0625L/100km per year and depending on where you started for example using my vans numbers at 13.5L/100km would represent approximately a 3.7% total loss over 8 years, not 6% over three as in the Tesla example.
@@Outsider.Reviews. I'm not saying don't switch, I'm saying comparing battery range degradation in an ev to loss in fuel economy for an ICE vehicles is not a strong argument.
@@huntsbychainsaw5986 yes but EV technology is very early in its life. That's why I laugh when people complain about losing value on their EVs when they bought the first Gen of a model... Like come on, you didn't expect the tech to advance and render yours less valuable? Also, LFP batteries have almost NO degradation so now that 6% is more like what ICE vehicles get which is next to no loss in range. All that advancement in the last 5 years, I can't wait to see what we have in another 5 years.... Besides ppl crying their EV is worth 50% of it's original value... Whatever happened to buy a car and keep it until it dies lol
@@Outsider.Reviews. Yes, exactly. I agree there. Depreciation is only a problem if you sell it. Right to repair legislation and ending planned obsolescence is something I'd be happy to see.
I don't believe you
That's fair. You don't have to. I'm just glad you clicked on our video which helps us out vs AI channels. The study is real and I'm just giving you my opinion on it along with some very basic math but I appreciate you giving us your opinion and feedback to help me grow this channel. What would you improve and such. Thank you
Clickbait BS!
You say Tesla did it to themeselves - they are using the government system for EPA estimates, so blame the EPA system, not Tesla.
Claiming in the title or thumbnail but then explaining it in the video contributes to the FUD. You do explain it, but it is still BS clickbait.
You clearly attribute the loss to time, but it is not, as 30% is when new.
little known fact, the manufacturer chooses which EPA number to assign to their vehicle. The EPA does NOT test all the new cars that come in but they offer 3 different brackets of range suggestions. Tesla chose the highest one which can only be achieved in a Lab, however most manufacturers opt for the middle or conservative range which is why you see videos out there of GM Ultium platforms going further than it's EPA range estimate and Ford reaching it's range estimate. So yes, Tesla made the choice!
You might want to talk to Jay Leno his Tesla battery degradation has only dropped 5% and that's been 10 years of driving so you're just wrong
Jay has how many cars again? My point is the man with 20 cars might not be your best reference in durability since he's probably not charging it as often or putting as many miles on it. This study followed over 12 thousand Tesla's . I think I'll take the word of a study containing over 12k samples than the one guy who has 20 different cars to drive daily. Also, I'm not the one making these numbers, the study from Recurrent Auto is. I'm just doing a video about it
Tesla's battery warranty is 80% for the first 8 years/120000 miles. My Model 3 2018 long range rwd has lost 11%, at 80000 miles.
That tracks with the study model of approx 2% a year degradation
Hmm, how can I turn 2.5% into 36%? Oh I know!I are dumb.
Who needs math when you've got creativity, right?
Lame video - Teslas are losing ~4-5% in the first 3 years of use.
Lame comment... CubbyTech didn't watch the whole video which is obvious because I specifically say Teslas lose closer to 6% on average in the first 3-4 years. Next time...watch the whole thing before you put your foot in your mouth
This stinks.. move on.
No
it is not a 6% degradation but an 8.5% if you use 70% as a starting point
From 100% it calculated a 36% degradation but in reality the 70% is the starting point... Maybe I'm rusty but doesn't that add up to a 6% difference?
@@Outsider.Reviews your graph showed that the actual "100%" range was 70% from the theoretical/EPA range at the beginning and 64% at the end. So, if we do the math based on this information, the calculation goes like this: 100%*(1-64%/70%) = ~8.6%.. This is still considerably less than original -36% claim..😀
@@markkuelo5191 that's probably why I got in the army as an infantryman lol Math is not my strong suit I guess 🤷
That’s wild that it’s 30% down and people just accept it
Yup. They bought in and never looked back.... or around... or anywhere lol
My ICE lost over 30% of its EPA mpg the day I bought it. Scandlous, who do I complaign to?
@@Alantj22 this channel my friend! I'll get the word out! Heck maybe even do it with you via videoconferencing 🤷
You don´t seem to realize that the results in Reccurent "study" do not have the same type of driving as an EPA test cycle. The data includes all drives, meaning drives in winter or with towing, which obviously decreases range of all EVs. Realworld range in Teslas tends to be single digit percent bellow EPA, some manufacturers do better, some worse. The new EPA rules seems to improve the situation. Overall degradation of the actuall battery capacity seems to be around 2 percent per year. If that is acceptable is for each of us to decide.
That's exactly what I said in the video. The actual degradation is 2% per year and even better, it seems to slow down after 3 years because year 3 and year 4 showed almost no degradation. As for the EPA standards. What actually happens is the EPA gives the manufacturer the choice between 3 brackets. Most OEMs will choose either the average or the conservative bracket, however, Tesla always chose the best case scenario range estimate and that is why their vehicles are consistently getting 30% less range in any range test (no towing) done by automotive journalists. The exception is this year's model 3 which was mildly refreshed with better tech yet lower range estimate than its predecessor. It would appear Tesla is learning from exaggerating its range estimates.
@@Outsider.Reviews Can you point out such test, where the range was 30 percent less? I´ve watched at least a dozen and it was never that bad as long as the drive was actually 100-death, not just estimates.
@@michalfaraday8135 yes it's from 7 thousand model 3s and 5 thousand model Y followed by Recurrent auto. I display their graphs on the video but I'll add the link in the description this afternoon. Thanks for pointing that out
That's not true.
Which part isn't true?
@@Outsider.Reviews the depredation. You may have a bad battery but the majority of those batteries are lasting a long time. Far exceeding expectations.
@@matthewtatarian147 so your statement is that the 36% degradation isn't true? Or the 6%…
Your twisting the results to put up a big percentage. In my would that's not true. It's click bait and wasted my time.
@@matthewtatarian147 you failed the test Matt! The thumbnail is one thing, watching the video is another. There's literally a warning in the video about clickbait AND I flat out explain how the numbers are skewered and what the true numbers are. Must pay attention and real the entire question Matt lol
