Why would you get that number after purchasing? I‘d never buy an almost six year old ev without a bettery certificate.

If it’s a long range model that’s still fine and expected given the age.

The first 10% of the SoH drops fast anyway then it flattens out, so it’s pretty reasonable. LFP battery handles 0-100 better but it will degrade. Not to mention the compared 2023 one anyway has a bigger battery to start with so you would never get to that range anyway

Two different types of Batteries, people should not be buying legacy models pre 2022 or it will come with lots of regrets.

How did you get the percentage in the app? Mine just says its healthy.

Yeah it’s a long range. I don’t ever feel like it doesn’t have enough range to get me where I’m going, especially given the amount of super chargers in my area.

Same 2025 M3LR

Did you run the full test?

Thats what im asking is it app or car?

App but you need to run the test in the car first

A few weeks ago I cleaned leaves, pollen, and bugs out of the radiators on my 2019 Model 3. It improved my range. I highly recommend it. I did not remove the front bumper but was still able to clean 80 — 90% of the blockage.

I have a 2023 with LFP batteries and charge to 100% regularly for almost 3 years and 43k miles i did a battery test and came up at 96% one year after purchase and 93 percent in late January. Mileage range drops a LOT in cold weather, but in the summer im still getting 250 plus on a car rated for 272 new. LFP has been the bomb for me

So you lost 7% in less then 3 years. As I mentioned the first 10 drops quickly. Not in months both the 4 year-ish is right around the ballpark. For reference I have a 2019 LR with 86% of SoH so that’s 14% in around 6 years, and OP lost 15% in about 5, all of these are in the same bucket statistically speaking

My wife charges her 7 year old 2018 Model 3 at home on a level 2 Tesla wall charger almost exclusively. She has 130K miles on it. She still gets around 270 miles of charge when the temperature is decent. <shrug>

Will see as LFP batteries flatten (more) after initial drop. I have a 2024 model Y LR AWD thats 1.5 years and 25k miles that was at 92% after a year. It was a noticeable difference in intial battery degradation. Havent run a test on it this year but i do see the LFP batteries as being more robust and easiest to “live” with (but really take a hit to range in cold)

You’re comparing apples to oranges you and your friend has different battery chemistries. He has an LFP and you have a NCA. LFPs are known to be much better at preserving battery health. NCA as mentioned earlier degrades the most within the first couple of years then slows down. The test showed your battery is health and within limits. Just drive and enjoy your car. 🤦🏻

Definitely feel the extra charge time now on one of our typical routes HOU<>RGV. For city driving, keeping it at 60% SoC still gets us everywhere we need.

I mention the chemistry. His battery is also bigger from the factory.

What’s your mileage? I believe thats what important, not the age?

The battery test makes your battery worse. So every time you run this, expect less range and less percentage.

The cycles count, not the mileage or age. While they correlate the devil lies in full cycles. My mileage’s is over 90k

What's this about keeping it plugged in? Isint a battery happy place 55%? So if I plug it in and keep the limit at 55% (when appropriate) will be the winning formula ???

Oh man, most people fail to indicate if they have FSD or not, if you only aim for “battery certificate” you cut almost 95% of listings. People forget to put VINs, some later refuse to disclose it even after you ask. One guy claimed “autopilot included”, which was actually FSD. Not everyone is tech savvy.

Yep

That’s not true at all. Bot matter, cycles and age. If you don’t drive a lot the age degradation will outweigh the cycle degradation by a lot. In addition to that average SoC over time and temperature play a big part. A car that was mostly charged to 100% in a hot climate will most likely experience more degradation than a car that was only charged to 80% in a moderate climate.

Yeah not everybody lists it right away but you ask for that stuff before buying lol. If they can’t deliver you choose another one. It’s not like model 3s are ultra rare.

Yep. Road trips are my biggest gripe. I frankly didn’t realize how much a difference 270/207 range makes. Not only it drives less, but apparently it also charges much much slower. It’s not a big deal for city driving, but I’m on my first road trip and need to drive from Flagstaff to LA tomorrow. Typical trip includes a 140 mile stretch of I-40 between Barstow and Needles which my car wouldn’t be able to make no matter how long I charge in Needles. The necessity to take a longer route and charge more often adds up an extra hour to the trip. LR cuts it even further but only by 20 minutes.

Some people say it’s 70%, some say it’s 60%, I don’t know frankly. But Tesla itself recommends to keep it plugged, I guess the car can keep battery warm this way (when not plugged in, battery preconditioning starts at lower temperatures).

Well, I saw the range when I bought, it’s the same after battery test. As I described in a different comment, I didn’t realize how big of a difference it’s from a practical standpoint.

The second part, while true, makes no sense in this context. Age and mileage are only relevant because of natural loss of SoC that would lead to different cycle count. It’s simple, if you don’t drive it but keep it charged always to 80% then you still pump in the cycles, that’s why.

That’s not true either lol. A battery will age regardless of cycles.

I’m not sure what part you don’t get. Sure, calendar aging can degrade battery but it’s statistically insignificant compared to cycles, provided it’s not kept in extreme conditions.

You are so confidently incorrect it’s funny. Just have a look at the data yourself. [https://www.geotab.com/blog/ev-battery-study/](https://www.geotab.com/blog/ev-battery-study/) https://preview.redd.it/qatpdg149hmg1.jpeg?width=1320&format=pjpg&auto=webp&s=b13ecd5313aa071b3103d2f14cae6b5af0df7b58

Damn dude, if it makes you feel better, I hopped on the Tesla train with very little DD and bought a used 2023 RWD before realizing the staggering difference btwn the Refreshed models. Ended up losing money but traded in my '23 RWD (amazing car btw) for an almost new M3HP. The regret was eating me alive and even though I threw a couple thousand down the drain, I don't regret it one bit lol.

How so?

Staring with the LR range helps vs a SR for sure but it did take me by surprise that it’s a thing that will affect the car for as long as we own it. Aiming to keep it for a good 8-10 years and I do enjoy the occasional long road trip so we’ll see when getting between superchargers becomes an issue (especially in Mexico). The reason it takes longer now is because we’re charging more of the battery compared to its total capacity when before the same kilowatts was a smaller percentage. Eventually will need 100% charge to make 150 miles at 80mph and that’s a good +40min charge.

Oh man, Mexico is so spread out with chargers I don’t even dream about it ;)
