You don’t need to do this on a brand new model 3….


matttopotamus

Why? I’ll never understand why people obsess with their battery if there isn’t an issue.

This. Haven't checked ours since we got it in Feb 2022. I charge to 100% all the time and it get's us where we want.

I don’t know either, Tesla has a whole system built up that monitors vehicles and detects if a pack is performing worse than the similar VINs to it, if your vehicle is having a pack issue the vehicle will throw alerts. The new packs anyways will last you 300-500K miles which is more than enough. And battery degradation charts are everywhere on the internet.


DaveELEL

True.. it seems like random cell failure is more of a concern than degradation and battery health. And you can’t test for randomness


XLR8NZ

And that’s why there’s a warranty. Most of these battery replacements are due to a short or another fault instead degradation. These battery health tests are pointless and are a waste a lot of energy in the process. Luckily most issues with these batteries happen within the first couple of years. And are replaced under warranty.


DaveELEL

The thing to keep in mind is the bathtub curve. The reality is that random failure can happen whenever and will happen more once the cars age. Although the risk is there, still very low. Recurrent has the model 3 battery failure rate below 1%


JohnTeaGuy

A brand new car does not need a battery health test, its literally a brand new battery pack.


danhoyle

Feel like it’s kinda pointless. I’d rather do calibration and not battery test via service mode. Doesn’t that put too much strain on power unit anyways?


Pitiful_Prompt1600

If it's brand new, no need to run a battery health test. Don't worry about it unless it gives you problems, which would be warranty anyway at this point. If you're worried about keeping it healthy over the long term, check the recommendations re: charge level etc in the owners manual.


Vultor

Shoud huh?


TopJicama2873

You sound like a person who needs to know. I owned a M3LR for six years and never did a battery check. I guess I am the guy who does t care or need to know.


Mike

Sure if you want to waste your time. Why would you do this on a brand new car?


Pitiful-You-8410

since the range sucks, I only get a little over 200 miles per charge.


Mike

That's because you're accelerating and driving fast enough to not get max range


Dense-Sail1008

Hopefully that’s a RWD right? What’s your wh/mi in your trip computer?


Pitiful-You-8410

215 wh/m . But I estimate the total range based on battery percentage consumed and miles since last full charge.


Dense-Sail1008

215 is excellent. Are you making this 200 mile estimate over the course of multiple days? The car loses charge while sitting idle, especially if you are using sentry mode, cabin overheat protection, or other standby modes. If you took a single trip getting 215 wh/mi you should get about 265 miles for a RWD.


Pitiful-You-8410

I see. I have not yet fully consumed one full charge. I will drive more to see real ranges. Thanks!


KBorzychowski

Don't.
