How do I know if I have a LFP battery?

How do I know if I have a LFP battery?

If your Tesla isn't on fire...

OK, I'll cut that out. If you have a model 3 SR bought fairly recently you have an LFP battery. If a model Y, a few came out with LFP batteries I believe, but they are "unicorns." If you have charge options showing only 50% or 100% State of Charge possible then you have an LFP machine.

There is no US market Model Y with LFP.

I had my model 3 set at 90% from 2018 to the middle of 2021, so my opinion is no. I am not getting into it more than that though, as I am very (very very very very very very very very very very very very very very...... (tack on about 1000 more "verys" there) fatigued with the "range / battery" discussions since I see multiple threads daily created I have to move to our master thread on the subject in the model 3 subforum here:

Range Loss Over Time, What Can Be Expected, Efficiency, How to Maintain Battery Health

The reported range you're looking at is NOT adjusted for weather or driving style or anything else. It's just battery SoC multiplied by EPA rated efficiency. And as @UncertainTimes said, battery SoC is really an estimation, there is some margin for error. My 265 mile EPA rated S P85 used to...

Its 210+ pages, and a large part of it is stuff like "should I charge to 80% or 90%?" whats the best way to take care of my battery? My range is only....." so Yeah I am not the right person to ask, due to my fatigue at the question.

This isn't the Model 3 battery. This is the LFP.

So, just got 2022.4.5.17 and it states:

The range display in your vehicle is undergoing calibration. Until calibrated, displayed range may under or overestimate compared to distance driven. To improve accuracy, charge to 100% and wait until the charge port LED turns solid green, indicating a completed charging session. It is recommended for this configuration of vehicle to keep your charge limit set to 100%, even for daily use, and that you also fully charge to 100% at least once per week.

So, I keep my daily at 90%... this seems like a significant change to how we've learned to charge daily, no?

2022.4.5.17 Release Notes

This is the LFP battery, it's not the same battery for which you often hear pages of discussions about.

If Tesla took the time to create the notification, then maybe Tesla thinks that you should follow the guidance.

I'd do what Tesla recommends.

I have a M3P delivered last Saturday. What do you think?

Beautiful car! Our M3 SR is used for local driving only, thus this is the model we opted for. Our MY LR is used to get us back and forth from AZ to Cape Cod twice a year. So we have the LR MY for that purpose.

Decide what you want the car for and pick the model which most closely fills yours needs.

Not LFP.

From the M3 Owner's manual -

Some vehicles are equipped with a Lithium Iron Phosphate (LFP) Battery. To determine if your vehicle is equipped with an LFP battery, navigate to Controls > Software > Additional Vehicle Information. If your vehicle is equipped with an LFP battery, "High Voltage Battery type: Lithium Iron Phosphate" is listed.
