From 2022, many Teslas come with a Lithium Ion Low Voltage battery pack. This has some benefits but can also be more difficult to deal with if it runs flat. This battery typically has a voltage above 12V and as a result a normal car battery charger may not work. If you get a flat battery with these cars then roadside assistance may be the only option.

If the 12v battery is flat then it can feel pretty terminal for the car, the doors won’t unlock, the computers won’t fire up and more worrying the main car battery will not charge. Tesla charge the 12v battery from the main battery pack, but Tesla also take the view they must protect the main battery pack as much as possible and if it is running low may put the battery into a deep sleep/low energy mode. This minimises any drain on the battery preserving its life, but this equally prevents it topping up the 12v battery and effectively paralysing the car.

I just had to buy a new battery for my laptop after about 2 years. This kind of lifespan is adequate for a $500 laptop, but not so much for a $100,000 car. Plus considering the fact that a new battery pack probably costs tens of thousands of dollars, it isnt exactly something you can replace every other year.

But there’s no telling for sure how much that has to do with Tesla’s batteries. Instead, because Tesla has not given specific figures for the Model S battery, they can use the identical chemistry NCA battery from the 10kWh Tesla Powerwall as a proxy.
