Battery Health after 12 mo

Nope seems very normal

Nice! I have similar numbers on my 24 M3P. My 1 year came up back in August and it was 97%. Now I think it’s somewhere between 95% and 96%

The degradation doesn’t linearly fall off. Your car will hit long plateaus where the battery will degrade slower. 95% seems normal.

How many miles? That is probably more important.

Nice did you mainly use supercharging or home charging ?

How do you check this?

According to our data on thousands of Tesla Model 3 vehicles, most experience 3-5% degradation in the first year, with the rate slowing significantly afterward. As others mentioned, battery degradation isn't linear. You'll likely see your battery health stabilize and enter longer plateaus where degradation becomes much slower. Our data shows that after the initial break-in period, Tesla batteries typically retain excellent capacity for years to come.

Battery Health Test

Mostly home but I thing previous owner used supercharging

How do you check this?

>Is this degradation more than expected Yes by a lot. Sell the car now.

Normal.

Battery Health Test and you have to run the test overnight to get the result.

Im at 80% on year 3

How long did yours take?

Normal to drop faster in the beginning. I’m at 97% with 3.5k miles. It tapers off and hardly drops anymore as it gets closer to 80-85%

Less the expected: mY 2019 sr+ model 3 has -11% in 2 months, normal use rarely supercharged

What’s your current mileage? My 3 month old MY AWD is at 95% with 7K miles on it. I am concerned

100%, I wouldn't waste time running this check unless you have a ton of miles or your range doesn't feel as expected. Also, check your wh/mi in the trips to make sure there isn't something up there (heavy foot does not apply). 1. You can calculate pack degradation based on charge level. 2. Tessie makes this very easy. 3. My 2022 M3 LR awd was 89%, and the pack failed at 101k.

The only reason I tested is I bought used. Just wanted to reset it for range so I know where I started.

Please don’t post if you don’t have anything positive to contribute. Reddit is a community for learning and helping others.

Mine is only down 1% in 3 years but I live in warm climate and my model3 has the LFP battery, which is probably why?

Exactly LFP is superior chemistry but looses on weight.

I am not sure if this a bot. When I bought the car recurrent showed battery health at 99%. When I connected the car after purchasing it showed 92% with 1 week. It seems like their model is support seller without real data. When I communicated with someone on their team they said they estimated based on curve which I don’t think is correct.

It’s bms Calibrating, so based on mileage, your diving style, charging style, at soc. I wouldn’t worry about that and focus more on how much percentage = distance since charge. 10% should get you 30-35miles at 70% miles per hour in highway. Mines 5 percent drop with almost 15 k miles. Bought it in may

...and power. I wouldn't call it superior.

Will you share a little more about 99% you saw when buying the car? That might have been Range Score, which estimates the Expected Range Today / Range When New. That number can differ from State of Health (SoH) but I want to be sure that I'm giving you the right info. A sudden drop in SoH would be a different story.

I’m at 92% purchased Aug 2024 and have 13k miles

Your battery’s energy retention is within the expected range based on its age and mileage.

I'm at 8530 with my Juniper AWD I got in April. I'm also at 95%. I think it's normal, but need to do the battery health test. It showed 97% for me back in August.

Totally understand!

I’m around the same, well 96% last time I checked. I’m not concerned

Same here

Just did the test on my 2023 std range and had 93%. 2 years old and 60k miles.

I wish I could do this, but I don’t have a home charger 🥲

Keep in mind recurrent doesn’t acct for wheel/tire size changes.

It was a range score. It was 99 when I bought in Oct and it changed to 92 as soon as I connected through my tesla account

Go supercharger!

I charge at home lol

I took abt 14 hrs. That too because I had car at 18%. Also I usually run my wall connector at 32A. I should have change it to 40 and probably would have saved few hours

My '23 MYLR is at 91% with 38k miles

Normal.

It says right there in your post that it’s normal? Why would you think otherwise?

What’s your mileage??

41k

I am not sure what Tesla metrics are for normal. This is to discuss with fellow Reddit user what they have observed and educate myself

B….but it says right there? “Your battery's energy retention is within the expected range based on its age and mileage. Your vehicle's high-voltage battery, like all rechargeable batteries, becomes less effective over time due to aging and usage”.

See for yourself the discussion and how much more you can learn.

I took a peak but nothing pertinent? Certainly nothing beyond standard battery chemistry information. What is it you think you learned from this?

Learning is relative. If you have more to contribute educate us if not don’t waste your time

I’m trying to educate you all by telling you the battery test you ran says everything is fine? The text in the image says so right there? Am I being punked? Let’s boil this down. What you ultimately learned is that your battery is totally fine lmao? Is that not the case here as well???

Peek vs Peak?

Have had 2 model threes over the last 6 years. I’ll fill you in on a little secret. The most common cause of pack failure isn’t the batteries, but components or wires inside the pack. When a pack fails, they swap it out with someone else’s refurbished pack and send your to be fixed - “refurbished”. Had that happen to me 4 years in, and all my diligent care for my battery health now in someone else’s car. I came to realize you don’t really own the batteries. What you own is a promise that the pack will perform as described during the warranty period. So earlier this year, I traded in for a new Highland and refurbished my warranty. Planning to keep it for 8 years or 120.000 miles - whichever comes first. I’m not suggesting you abuse your batteries, but try not to get too hung up on their welfare.

Lfp batteries are the ones that degrade faster in the beginning, while the NMC batteries can show 100 percent even a year or two in.

I have 101,236 miles in my 2019 LR Dual motor and have 86% life.

My 2020 M3LR has 83K and just tested at 90%.

Sitting at 84% and just crossed 50k miles myself in my 2022. Given that I primarily supercharged during my first year I was happy. I also think the guidance at the time was charging to 90% was OK but they’ve since said that 80% is the new standard.

Definitely not a bot after replying I assume 0 o 0
