Tesla Model Y and Model 3 With LFP Battery After 43,000 Miles

We have a comparison video of a 2021 Model 3 with LFP batteries being compared to the battery of the Tesla Model Y long range. There will be a comparison of battery degradation. Let's see which battery degrades more.

After 17,728 miles, the standard range Model 3 with LFP batteries was at 96.9% of its original capacity, which is a 3.1% degradation. This dip generally goes to about 10% and then levels off. This leaves a little less kWh the car can use and gives it a range of 245 miles.

The Model Y, Model S, and Model X do not have LFP batteries. The RWD Model 3, which I own, has LFP batteries. The 2022 version has 272 miles with the tires I have. I've already charged it a few times to 100%.

The 2020 Model Y has 43,400 miles on it and the battery health is 86.2%, losing 13.8% of the battery for the car. The original capacity of the battery was 77.3 kWh and it is now 66.7 kWh. This is a below average battery degradation for the Tesla fleet.

It looks like the Model Y is on pace to degrade more than the 2021 Model 3 RWD with LFP batteries. The biggest thing to note is that the LFP battery can be charged to 100%. This gives it an effective range comparable to a longe range Model 3 at 80% charge.

There were other uses of Tesla vehicles who shared their experience in the comment. One was a 2021 Model Y long range with 49,000 miles and the battery degraded only 9.3%. This person mostly charged at super chargers.

Tesla has a warranty on the batteries of its cars, a four-year, 50,000 mile warranty and an eight years, 100,000 mile warranty. If the battery degrades more than 30% after 8 years, you can get it replaced for free, I believe.

I look at it this way. If I drive my Model 3 for 10 years, by that time, new batteries will be so much better and hopefully cheaper, that I can just go get a new battery pack that has a lot more range.

What do you think of this battery performance test? Will batteries be a lot cheaper and better in 5 years? What about 10 years?
