Waking up the next morning its nearly 7am as you can see the car has completed the battery health test because it no longer says 100% as we are now at 85%. So a little over 50,000 miles my car is telling the battery has degraded 15%. But is this really true… to be honest I’m not sure what this tells me. Looking at my other handle app called Tessie. We can see this states my battery health is at 88.1% with a degradation of 11.9%. So it is pretty close to what the tesla says with a margin of 3% ish error. Comparing my mid-range model 3 to the rest of the fleet shows I’m pretty much in line with everyone else based on my mileage. The chart also shows I’m still in the so-called green area and that my battery is operating normally. Let me know what you guys end up with after doing this test. Is there more information to this batter test that I know of? Again I’m 100% certain of what this result actually means. Also after doing this test please make sure you do not leave your tesla sitting at 100% state of charge unless you have the new LFP battery. Because I did not have time to drive my car anywhere and left the heater on high for a good 40 mins to bring my battery down to 95% before I could drive it later that evening. If you found this video helpful consider dropping a like down below so current and future tesla owners can find this. My name is Evan and until the next video stay safe and I’ll catch you on the next one… bye.

Love your videos Evan - thanks for doing this so we can all know what to expect. 👍
My pleasure!
going to try this on my plaid tonight!
What was the 3 commands to start the test? Up on the stalk, brake, and take out your key card?
I have Model 3 SR+ 2019
Original EPA rating was 386 KM at 100%
I don't drive with Aero covers. Elon said without aero covers we could loose 4% so 371KM
Right now I get 350KM at 100% so I lost about 5.5%
I have stats app which is showing same number as well
Hey Evian. Glad I found you. So I have a mp3 with 0 miles then after around 1500 I went from 100/ 315 miles to 100%/ 303 miles. Is this normal.
You mentioned app is that for your phone how do I get that app? I don’t have a level two charger at home so I wouldn’t be able to perform the test through the service page.
2018 Model 3 LR RWD
76k miles
4 1/2 years old
Results of battery health test: 87%
Miles at 100%: 292
This result seems weird because it implies that when the car was new, it should have had 334 miles range. But it was advertised as 310 miles. A later software update supposedly bumped it to 325 miles, though it only went up to 313 or so for me. Maybe "battery health" is not the same as capacity now / capacity new.
If I calculate based on the current range and the original range, the battery is at 94%, not 87%
During the test there were loud fans at first. The battery discharged at 12% per hour at first, and slowly tapered down the rate of discharge. When it got down to around 7% the fans shut off.
At some point, the battery test spontaneously canceled, and I had to re-start it. That was the only glitch.
After it recharged to 100%, it said the test was still running. It took about another hour for it to finish. The whole test took about 16 hours. I started at 25% SOC. My charger is 48A at 240V.
This Glitch of needing to restart it, happened to me twice and then never showed me the results. Frustrated haha. 2020 M3P+
Identical year and model my comes on full 296 pretty much the same here so we good!
Forgot to mention my is 50.000 miles
They did bump the range of the car via software updates several times since we got our cars.
Works with my '15 model S as well. Have one error. (PM_w041_dasMIA) So now I know my car is not error free...😲
How often do you supercharge it? Sucks you can perform this test when shopping the used market.. wish there was a better and faster way to test this
How long did the test take
2019 Model 3 LR, 105,000, battery health showing 87%. This is likely an objective test of battery health, however I don't think it's as simple as applying 87% to the range when new to establish how many miles you can drive on a full charge. So many factors go into the watts per mile that battery health isn't necessarily going to give the user, or buyer, a clear picture on how many miles a full charge will give them. That's going to depend on vehicle configuration, temperature, and driving habits.
Hi. Why I don’t have that “battery” option to click on ? Mine is 2023 model Y
thx interesting
How did you take it out of Service Mode after the test?
15% degradation over 50k miles seems like a lot
Anyone tried this with a different model? Like the X or maybe a 3?
Didn’t work for me. Went out the next morning and it had charged up to 100% but didn’t have a battery health percentage. It was just blank.
Yesterday I tried the test on a 2019 SR+ starting at 4-5% SoC. It did simply not start working. Moreover, after exiting the test the charging would not even start normally. It is then necessary to unplug everything, move the car a little bit forward and back again (of course by driving) and then charging is possible again.
Someone else who has those issues? The problem is that my M3 is a refurbished one from Tesla itself and it gives mit a mileage of around 320km (200mi) rather than 400km (250mi). So either the cells are not well balanced or I got a car with a bad battery pack. More confusing is that Tesla itself did not perform the test before handing the car over to me.
@1:02 What does it mean, "key" to authorize, plus Turn Stalk and Brake..? what key?
...and, how does it discharge from 18% to 0... I assume, it runs the cabin or other heater full blast to waste power? did it get hot IN the car (cabin heater) , or did it do some other heating blow otuside?
It just runs the fan below the car(not inside the cabin) to burn off the excess energy. The key is your tesla key (the card)
Hello Evan, video interesting.
How is old your car?
What battery you have? (E3LD?) Panasonic LG ?
Capacity?
Regards
Its a 2018 Model 3 Mid-Range
Just performed my M3 LR health test. After 2 years and 42,000km my health test returned a 98% score.
Nice. What are your charging habits?
Thanks for this great video. But how to get out of service mode after we finish the test?
0:57 on pause shows a red horizontal arrow. Tap that to get out
Thanks for the video, I am purchasing a 2022 Model 3 Std Range, 14.000 miles on the clock, i dont have home charging as i leave in a flat, is my assumption correct that with the Tessie App we dont need to run this long test? Thanks again.
Yes, Tessie can help tell you the degradation after you run a few battery cycles. If you want to minimize battery degradation, try and keep the average charge around 50-55%. Tessie will not be as accurate as the Tesla method. It should get you close though. There is an issue how Tessie determines the actual battery capacity so don't expect it to be spot on. It is good watch it over time. Another option is to use recurrent auto and sign up for a free account. They tend to be pretty accurate but only if they have the right config for your car. For example if you have a current model S (2021+-2023), it is only accurate if you have 19" wheels. They data isn't there for 21" wheel cars and it will show about 10% worse degradation then you actually have.
@@wavshrdr8452 Thank you!
Did it take the full 24 hours to complete the test (how long)? Also, with Tessie, do you need to put it into service mode? Or does Tessie regularly monitor the health without going into that mode?
It depends on what your state of charge is when you start the battery health test, mine took only 12 hours because it started at 18% also the Tessie App will show you battery degradation regardless if you’re in health test or not.
@@EMtesla1 If the battery was at 50% would the test time be longer or shorter?
@@Russell_L365 longer
So far i started the test at 16% charge since it has tobrun ot down. It stopped at 6% not zero as i expected.
I'm waiting for the charge back to 100% on a 6 kW charger. The fans sure range a lot of the discharge.
Oh we could not lock the door during the service mode checking. I had to park outside because of all the heat and fans running. I can't wait for results. Our model Y only has 17k miles. Had 260 mile range which my wife felt was way to low. 70 and up to 90 here in Phoenix area.
I agree... My 2020 MYP w/ 20k started at 290 mile range, only supercharged 25%, range now down to 264. Hope it doesn't drop much more over the next 5-10 yrs.
Adter it got 100% i could only drive at 7 mph in service mode. I finally stopped that but got no data. My battery health shows ??
This is a bad test.
Great info, thanks for the help! Is there a reason you don't drive it off at 100%? I understand why you might not want charge it to 100% because of battery longevity, but why not drive it at 100%? Thanks for any help in advance! @EvanMichiels
I did not have time to, I was working from home... you can certainly drive it off to burn off excess battery. Thank you !
@@EMtesla1 He was asking why you wanted to burn the charge to 95% before driving?
@@TamilEelam1 You do not want to leave your tesla idle at 100% for a long period of time unless you drive it soon. I only charge to 100% for roadtrip purposes. Thank you!
I just tried to do the battery health test on my 2016 P90D MX. All the instructions you provided worked great and I was able to get into service mode no problem. But I could not find a percentage for the battery health or any place to tap to start a battery health test. Do you think that this is because my Tesla is 8 years old? Thank you for any tips and suggestions you have. My HV battery warranty ends in August of this year and I really wanted to see the data from this test. I've been calculating the old fashion way by charging to 100% and then comparing various points in time.
It may be the older vehicle with the type of software you have. If there is no High voltage section in the menu to tap on, you might not be able to do it :(
@@EMtesla1 First of all, thank you so much for your reply to my comment!!! I do have a HV section and it actually includes 3 things: HV System, Battery and HV Battery. Yesterday I filmed my hacking into service mode for the first time for a future video on our channel and in watching the footage I shot I just noticed a pop up message that reads "Low disk space. Free space to restore functionality." This sounds promising. Do you happen to know what the process is for freeing up disk space? I will do a search on this topic tonight but just wanted to check with you first in case you have first hand knowledge or experience doing this.
Sorry man, when it comes with the model S, I am not too savy with its specs.
could one simply charge to 100% and read the mileage range @100% and compare to the mileage range at original purchase to determine degradation?
No. The range estimate also accounts for vehicle efficiency. SOH is a measure of the battery health only.
The range at 100% could serve as an estimate or indicator.
I can’t find the post on what steps you exactly need to do prior to running the test?
I tried it a few times but it never completes.
Either 90% limit stops it or scheduled charging etc stops it and I have disabled both so it could complete but never does.
Any specific tips prior to entering service mode to run this test successfully while my battery is almost 10% please????
see it on my site: evanmichiels.com/battery-health-test
@@EMtesla1 you should add the pre setup steps that you and everyone else is missing? Turn off any scheduled charging via the MCU and app and make sure charge limit is set to 100% via MCU and App.
@@usasupra23 not sure what you mean. I left all settings the same… just read what the tesla says to do and it worked. I don’t think anyone is missing anything.
Hello . Just picked up a model y and I didn’t wanna charge it during peak hours so I charged to 90% on Friday and didn’t charge again until Monday and the battery was depleted to 3% . I realize now after my friend yelled at me that this is very bad charging practice but my question is did I ruin anything by doing that ? The mY only has 800 miles . I definitely learned my lesson now but hoping I didn’t ruin anything?? Please reply and help .. thanks
Nah… you’ll be fine. Usually best to charge at 10% or higher, but you can go all the way down to 1% if you really want. (I did this during road trips a couple times)
In my 2017 Model S 75D, if the battery is below 8%, then the Supercharger will be slow at first. But once it reaches 8-10%, it should speed up and supercharge like normal. It just has to be careful at low charge levels to protect battery longevity
What’s that battery health app you use?
Tessie
I don't have HV option or any options when I go into battery
Me either... I'm at 118,839 mi. and I need to check before warrenty ends!
Me either 2018 model
Your battery is supposed to stabilize degradation around 90% original capacity and they tend to think this is around 100,000 miles. Given you are at 85% with 50,000 miles, you may have yourself a defective battery and might want to closely monitor that as you approach the 120,000 mile warranty
Degradation depends on a lot of factors. They state the most optimistic figure under the BEST conditions, including air temperature, the way your charge and discharge the battery, ... If you live in hot states like California or Texas and if you in areas with a lot of traffic lights, your battery will be dead pretty quickly.
@@trumplostlol3007 I just ran a range test and got 245 miles highway winter driving around 55 degrees with a model y performance going an average of 67 miles per hour with 18 inch wheels. I am making a video about it on "Adventures with Nick"
@@ntrakstudio EVs are not for city dwellers in hot or cold climate. City dwellers won't drive more than 80000 miles in 8 years. By the time their battery warranties expire, they will have to pay over 20,000 bucks just to replace that stupid battery. My guestimate is most city EV batteries can last from 100,000 miles to 150,000 miles. Air temperature, charging, discharging, stopping, starting, ... will all affect your EV battery life by A LOT. It is an electric car, not a mechanical car which is much more robust to environmental conditions.
@@trumplostlol3007 your comment is chock full of misinformation. To repair bad cells in a EV battery and having working like it left the factory floor you merely replace the bad cells and NOT the whole battery. There are many EV shops now that provide the service for a couple thousand (sometimes much less than the cost of a gas engine replacement). One of the shops is called Electrified Garage. Get your head out of the sand.
Additionally, I live in CA, my Tesla model 3 performance is 2 years old and has 22K miles on it and its my daily city commuter. I average 220 Wh/mi in 40 degree and 90 degree weather, which is actually 30 Wh/mi less than rated. Also, my battery health is only at 6% degraded. You obviously dont know what the fuck you're talking about.
@@trumplostlol3007 your guestimate is wrong
Under service mode it does not list battery as an option
Lightning bolt, then hv system
Odd, I did every step you did and I started the test at 10% and 4 hours later it’s only at 4% and never heard any sounds from the car at all as if the test is t running but I do see the choice to stop the test.
So what happened?
@@OneHonestGuy tried it again and once I seen it finish via the app I went out to the car and there was no data. Didn’t show anything at the end like his did
@@usasupra23 Did you try it again?
@@Russell_L365 I gave up as it’s winter now here.
Battery def seems so degraded to me
Thanks for the video. My test went through without any problems. The result is 12%. What does that mean after 10,000 KM. My range is 100% 462KM.
There is a bug in the test that affects some cars. Kyle Conner got a similar result when he tested the battery in his 2019 Model 3 Performance. I think he did the test about a month ago on one of his "Out of Spec" channels.
Same result. I wonder if it means 12% degradation
How much time did it take for full test?
@@vkay4148 it's been a long time. I mean it was 6-8 hours.
What is the average state of charter you leave your car at?
80-90%
@@EMtesla1 Just curious, I don't use too much day to day so I keep mine at 55% to preserve battery longevity. A typical day is 55-50% or 55-45% for me. But it's nice to compare how it affects the degradation. Thanks
I start the test but nothing happens beyond that prompt that test has started
Under 50%? Sometimes this is normal and you have to leave it do it’s thing
I thought the same but I left it and it did it’s job.
Came here to ask same thing, nothing happening, started test at 7%. Will wait and see I guess.
Is there free tool to check it? I would like to buy a second hand car. I couldn’t do this check.
What about the standard tesla model 3?
Is it okay to charge it 100% ?
any lfp tesla.
Ive got the 2022 Chinese MY, I put in the password "service" but nothing happens ???
Same here, were you able to figure it out?
Try service in Chinese 😅
Stupid question: whats the “Key” ? The card?
yes, the card
I tried this last night at 45% and it gave me an error and didn’t want to start.
Does the car still work as intended?
@@danvtec6942 yes, I assume it needs to be below 20%? Outside temperature was -1 C. Although not sure if it has anything too do with it.
@@JRCarReviews I really want to do mine but I’m afraid the car will brick lol
I know this is old video. But the Tessie app told me I was at 12.9% degradation after 4 years. Today it says I’m at 8.0%
interesting!
Does the car need to be plugged in for this test?
Yes
So I’m trying to buy a Tesla from a private owner. This would be impossible to do so what key things should I look at before I buy it? I used to use a code reader on regular vehicles but not sure I can do that on a Tesla .
Hey there... A trick I've been using to figure out battery degradation is to divide the percent of charge into the miles at that same charge. For example: My 2020 MYP is currently at 62% S.O.C., tap on the battery/miles icon on the screen to change from percent of charge to miles remaining. (164 miles ÷ 62% battery life = 264.5 miles at 100 % S.O.C. Sooooo... since my MYP came with 291 miles at 100% S.O.C., this means I've lost roughly 9% battery capacity or suffered 9% degradation in just under 3 years, with about 30% DC charging to no less than 95% when on road trips. 75 - 80% is my norm at home charging at 35 amps on a 240V line.
How do you exit service mode when the test is complete?
you hold the exit service mode button.....
I have run this test twice but I still didn't get any % M3LR 2022 (set the charging to 100% for the test) :(
Any idea on why?
* Edit:
Didnt know about Tessie, just checked Tessie 0% degradation, could that be the reason I don't get any % in the car? (Running the test just to make sure since I just bought the car ;) )
I did the test but no results :(
I still get a dash on the battery health… 😢
Basically u never know the battery health until u buy it, lol, so much technological advancement, 🤣🤣🤣
Damn, 85% health already after just 55k miles? I don't want to gaslight you and I am no Anti-EV at all, just a bit shocked. The early Model S that people were beating like crazy (because of long warranty), had great health even after hundreds of thousands of miles and many years. So I don't know, this seems a bit low to me. I do know Tesla replaces the battery below a certain %. 70% I think?
Batteries dont degrade linearly
@@ThisaraGamalath can you elaborate? So at 100k miles he wouldnt be at 70% ... ? I want to buy a used tesla but scared it will need a new battery a year or two into ownership...
@@RummageBuddy no, in the first 20-30k miles you see an initial drop in health and after thats its very minimal per mile vs the first 20k. you might lose 2-3% until it reaches 100k and another 203% at 150. There are model 3s with 300k on the battery still doing fine
@@TechMultiview100 I think you meant 2 to 3% a second time rather than 203%.

That's horrible sir
Its not. The degradation is on a logarithmic scale, it slows GREATLY after the first 20 to 50K miles. He'll probably get hundreds of thousands of miles in this battery and will eventually be able to repair/replace only the bad cells (not whole battery) for a few thousand (cheaper than a gas engine replacement). Lots of EV repair shops popping up.
