I recently purchased a 2019 Standard Range Model 3 for $29K. I have done some more research on this car and have seen that the battery is software locked to around 220 miles. However, my car when charged to 100% shows right at 200 miles or sometimes a little less. Is this normal for a 4 year old car? The car has 75,000 miles on it so would this qualify for a battery replacement from Tesla? Is it worth spending the money to "unlock" my car to be a Standard Range Plus? I think I've seen it's around a $2,000 upgrade without autopilot.

Does my Model 3 need a new battery?

The answer to this is "Absolutely, positively, unequivocably No". The warranty is for 70% capacity to 100k miles. I believe those started at 220 miles (software lock is completely, irrelevant to that number). 70% of 220 is 154, so you will not have any battery claim with tesla at all unless your screen lights up like a christmas tree with battery errors, OR you have 154 miles showing on the screen when charged to 100%

9% degradation (200/220 = 0.91 or 91%) is normal. You might be able to increase range miles slightly by charging from 20% to 100% to recalibrate BMS.
Tesla battery warranty is greater than 30% degradation.
Only you can decide if extra range miles is worth $2000.

...even when upgrading, the battery will still have some degradation. I don't believe you'll shoot up to the "as new" advertised range of the standard range plus.

Buy a new 12 V battery at the Tesla Service Center and have it installed. Under $100 for the 12 V. They get a lot of usage and the Tesla Forum is littered with howls from owners who get surprised by the battery dying suddenly,
The batteries seem to last about three years.

The OP’s main battery is fine. But the oft overlooked 12 V battery should be considered for replacement. Just a clarification for a new owner.
The 12 V lead acid batteries do not last as long as the newer model’s lithium ones.

This would unlock a 2019 SR with ~200/220 miles to ~218/240 miles, FYI.
So the unlock would take you to ~218rmi.
(~43.8kWh to ~47.7kWh; values are including buffer, so usable is 95.5% of these numbers.)
The lock is on the top, FWIW, so if you went ahead with this, you’d notice an increase in severe limited regen if you frequently charge near 100%.

I purchased a 2019 Standard Range (not Plus) Model 3 back in June of this year. I was curious if anyone knows the exact kWh capacity of this software limited battery. I have seen different answers on the Standard Range Plus having a 50-55kWh battery pack, but I wanted to see if anyone knows how many kWh is “100%” on this software locked model.
