What type of battery does the new, post-$7500 rebate Model Y Long Range/Premium come with? Internet searches are not conclusive.

Juniper US models use Panasonic NCA batteries.

Perfect, thank you! And to whoever downvoted my question, sorry if it offended you but like I said, I found conflicting answers from various different sources. Some other info I found about NCA batteries is that best practice is to not charge above 50% for daily use unless you will need more range for a longer drive. Has anyone else heard of this? I know 80% is the usual recommended max SOC for NCA and NMC batteries but some sources said that for NCA, 50% is even better to minimize degradation. I'm still deciding on whether to buy but I could easily manage to keep it at 50% max on a day to day basis with only needed to go higher one or two days a week.

And it's a good thing. I had a Fremont built 3 with Panasonic. My MiC Y has the LG and it is charging sooooooo slow in comparison. I would pay extra to get an us model again.

Interesting. The LG is an LFP battery, right? From everything I've read those experience almost no degradation, although they do have some downsides. It's kind of scary knowing a car is full of hundreds of the same 18650 or 21700 batteries I have in a bunch of my flashlights!

Personal recommendation? Don’t stress about the battery. It’s going to deplete no matter how you use it. For normal use, don’t charge more than 80% unless you’re planning a road trip. During the winter months, I keep my charge limit to 70% considering the cold drains the battery faster. For summer, I bring that limit down to 60-65% depending on what I’m doing / where I’m going.

Yeah, I know that NCA and NMC batteries will degrade, I'm just thinking in advance to how I can minimize it. I'm thinking about trading in a Rav4 Prime for a MY Premium and on the Toyota, my battery over 50K miles in 3 years has degraded by 17%. I want to make sure that doesn't happen in a full EV.

No. The LG is NMC. It uses less cobalt and is said to degrade less over time compared to the Panasonic NCA. The advertised 250kW is met only for a brief moment around 13-15%. My Panasonic Model 3 charged with 250kW flat from 3-27%. The charging curve of the LG is hot garbage in comparison. This is the same for the new LG battery with 81kWh. Same shitty charging curve. Tesla really needs to adress this, in markets outside of the us the cars are outclassed by competitors (concerning charging speed)

The Tesla is going to degrade in battery a good amount the first some years too though. I believe I read that time period degrades the most and then it stabilizes.

For example, my 2025 Model Y LR AWD (pre-Juniper) purchased in Nov 2024 had 18,000 miles and I ran a battery health test. It had 9% degradation and I keep it AC charged to max 60-80% depending on what I need

50% is ideal in terms of battery life but at some point good enough is good enough; and for almost all circumstances 80% is good enough. It’s also better to start at 80% and run down to 40% than start at 50% and run down to 10%.

Good to know. I ordered mine yesterday. It's in transit already so I should have it by next weekend. I'm thinking that with my daily commute I'd be ok charging to 60%. If my estimates are correct, that would keep me between 20% and 60% most of the time, then the days I know I'll have longer drives I can charge it up to 80%.

The NCA battery is likely to degrade much faster than lfp but has advantages too. Better performance and range especially in cold, faster charge and discharge. But I think generally EVs aren’t meant to last super long. Like 10ish years
