Tesla 12v battery replacement in real time by just reading directions

Showing how to replace the 12v battery in a 2022 Model 3 Performance by just reading the service manual. If you can read directions, you can do simple things on Teslas yourself.
There are 2 different types, ones with heat pump and the ones without the heat pump so be careful to make sure you are looking at the directions for the correct one.
Not sure what would happen if we disconnect the safety loop prior to pulling off the negative cable but there was a very notable caution about that in the manual.

Tesla replaced mine for free.
Less than 5 years old less than 50k. Tech came to my home and changed it out. Took him less than 15 minutes. I almost did it my self and waisted my money.
