Tesla Model 3 low-voltage battery, honestly explained

Which low-voltage battery your Tesla Model 3 has
Model 3s built through about 2021 have a 12-volt lead-acid battery. Cars built from roughly the 2022 model year on, including every 2024-on "Highland" Model 3, have a lithium-ion low-voltage battery (16 volts on most, 14.4 volts on some newer builds). The build date decides which one you have. On the car it is listed under Controls > Software > Additional Vehicle Information.
What to know about the Tesla Model 3
- The low-voltage battery runs the screen, door handles, locks, and the computers that let the drive pack switch on. When it fails the car can look completely dead even with plenty of range left.
- A 12-volt lead-acid Model 3 battery is small and the swap itself is short. Most of the work is getting at it and letting the car come back up properly.
- If yours has the 16-volt lithium-ion battery, that is a Tesla part. We tell you before we come out whether we can help or whether Tesla Service is the better call.

Where it is
On the Tesla Model 3 it is in the front trunk area, under the frunk liner and cowl panels. If the car is completely dead, the frunk can be opened by putting 12 volts on the two leads behind the tow-eye cover in the front bumper. That is how we get to the battery.
