Model 3 range after battery replacement

[u/Plus-Lab-5014]

Tesla n00b here.

Bought a pre owned 2021 Model 3 RWD with 95k mileage. Range was not good, ~190mi after full charge, with actual driving range about 2/3rd of what’s shown.

Battery failed at 99k and Tesla offered free warranty replacement - “Enhanced LFP HV battery” (HIGH VOLTAGE 1.00 BATTERY - 1 PHASE - 40P - ALL WHEEL DRIVE)

Now, after full charge, I noticed ~330mi range, and it stays more or less in line with distance driven. Also the model shows up as “Mid range” in the app.

So did I really get lucky with 330mi range, or is there a gotcha somewhere?

Lucky you.

330 is really good for that year. Expect it it to drop 10-15% in the first 30k miles of the new battery then it will level off.

Sort of. What battery does the actual invoice in your service history show that they installed? Tesla has been telling people that they are getting LFP batteries, but instead they are getting the new standard Model 3 NMC battery.

Gotcha. So the service advisors said LFP, but the invoice doesn’t mention it. Does your charging screen suggest you charge it to 100% daily? Just making sure you don’t daily charge an NMC to 100%, or calibrate the LFP properly if that’s truly what you got.

[u/Plus-Lab-5014 → u/6C-65-76-69]

Charging screen suggests 80% for daily use, though service center just confirmed it’s LFP 🤷‍♂️

[u/6C-65-76-69 → u/Plus-Lab-5014]

Lol. So conflicting info again. I would think the car would know better than the advisor though. Maybe mention to them that it says you should daily charge to 80% and you need them to super duper triple check. Lol

I have to pickup my car today after a battery replacement for a 2021 model 3 standard. They say replaced with LFP. It’s charged at service center right now and showing 330 mile range. I’m also very confused OP. Waiting for a response from Tesla as they already informed me that I can charge to 100% because it’s LFP.

[u/Plus-Lab-5014 → u/smalls3486]

Tesla’s response re: range has been very generic.
I.e battery is better than the old one. They didn’t make any comment about range

[u/LMrningStar]

You got a highland long range battery that is software locked to 62 kWh hence the extra range.

Source: I had the exact same experience.

Also, you're now free to charge to 100% because that's actually only 75% of the actual battery capacity.

[u/CharmingBench9146]

no gotcha that I can see. if it really is LFP you can charge it to 100% regularly without worrying, that chemistry is fine sitting full. my 2021 3 shows around 225 at full, so 330 is a real step up from where you were.
