Well, then all bets are off. Who knows how it was maintained before he owned it.

 

I charge both my leased EV'S to the recommended levels as well, even though I'll be moving on, but that said, from what I've read and seen from EE, you may shorten the life of the pack a little, but it probably wouldn't be noticable. And because it doesn't void the warranty (I double checked), they have factored this scenario in

 

leave it to you to provide an incomplete poor ev situation anecdote with key details omitted like your friend didn't have the car for all of those 59k miles.

you said it's a '22 model so let's assume there was 1.5 years of ownership before your friend got it at start of '24 and drove it for 10 months. how many of those 59k mi. has your friend driven (this year).

exactly. could have been an uber car, supercharged twice a day.

But in response to the anecdote I posted an article with detailed data on how the friend's Tesla degradation is definitely abnormal.

this 4y old video is relevant though, showing most ev's experience little degradation if treated right. The worst thing someone can do is charge to 100% and not drive the car for days.

Sorry I didn’t initially include all information but he believes he’s close to normal degradation. Obviously he would want to be right at 90%. I was just curious if anyone else has ran ran battery health check to gauge how close/far off he is. OnIy other detail I’m aware of is he bought it used from Tesla if that makes any difference. I believe he said he bought from tesla due to existing warranty or an extended warranty it may have (60k) don’t quote me on that.

I will find out how many miles he put on it.

 

Ok my apologies on my friend’s M3LR. It is a 2021. He bought it with 47k miles. Currently has 59k miles. He bought it from Tesla because Tesla added an extra year and 10k miles to the warranty so 60k mile warranty instead of the original 50k mile warranty. It’s coming back to me because he told me the 2022+ have a faster chip (Ryzen sound familiar). So 2021 model with 87.8% battery doesn’t sound bad at all right. Also it has the acceleration boost. That was a big selling point for him.

 

thanks for all the extra info! so let's say 12% loss in 3 years and 59k mi. or roughly 4% a year and 20k mi. per year. still seems a bit high (loss) to me but i'm sure the car is great anyway. your friend is only doing 1k/mo. so i doubt the range loss makes any difference.

i don't think i have a way to check my car's battery health without some kind of equipment.

 

if you don’t already have one, all you need is a Bluetooth OBDII dongle and an app like Car Scanner

My free Tesla made NACS adapter arrived today and it's very solidly made. Haven't used the A2Z at all but I have a long drive next week and switch between the two to see which connect/disconnect process I like better

 

usually most of the loss is in first 2 years and then it drops off.

I dont know what my 2021 Model 3 loss is, looks fine.

 

I need to get a diagnosis to see what my loss it since it’s been three years. I’m curious since my wife is complaining how the mileage we are getting daily seems lower. I tried to send a message on the app to Tesla but I get a standard message and when I try to send the message anyway I get an error in the app.

 

Can go into service mode to check if? I’m asking this based off the pic my friend sent me of him in service mode when he was getting a battery health reading. On the pic, he started charging at 1% and I believe he charged it to 100% if I’m not mistaken.

 

It takes awhile, you have to drain the battery fully, including the reserves, then charge to 100 percent. It uses up one full charging cycle. There are 1500 charging cycles

 

Can the service department do a diagnostic without doing that? I had it checked two years ago and it seemed like they checked it remotely somehow so I was hoping they can do it again. I emailed the person that did it last time to see if he could check it.

 

Here's the process, if anyone's interested: LINK

 

It depends on which test they perform. The detailed test which Mike posted will take longer, no matter who performs it. Tesla probably won't do the detailed test unless they suspect an issue with your battery pack, like unusual range loss
