The car cannot charge its main battery until the low-voltage system is jump-started, even if you are plugged in. Once the screen powers on you can plug in and charge. Source: [tesla.com (archived)](https://web.archive.org/web/20250401045434id_/https://www.tesla.com/ownersmanual/modely/en_us/GUID-CB07D968-612A-4FAB-977D-CD01C69464D0.html) ### Does the warranty cover the 12V / low-voltage battery? Tesla's manual says damage to the low-voltage battery from running out of range is not covered. Source: [tesla.com (archived)](https://web.archive.org/web/20251214135257id_/https://www.tesla.com/ownersmanual/2017_2023_model3/en_us/GUID-2588F809-41E3-43F1-84E5-6745C7C18DBE.html) ### Can I replace it myself? Yes for lead-acid cars: Tesla publishes a DIY procedure for the Model 3 and says to use the same type of battery. The North American part is the AtlasBX / Hankook 85B24LS 12V 45Ah. Source: [tesla.com (archived)](https://web.archive.org/web/20251214135257id_/https://www.tesla.com/ownersmanual/2017_2023_model3/en_us/GUID-2588F809-41E3-43F1-84E5-6745C7C18DBE.html) ### Which battery does my car have? Model 3 cars built in Fremont before about December 2021 (Shanghai before about October 2021) have lead-acid; later cars have lithium-ion. Source: [tesla.com (archived)](https://web.archive.org/web/20251214135257id_/https://www.tesla.com/ownersmanual/2017_2023_model3/en_us/GUID-2588F809-41E3-43F1-84E5-6745C7C18DBE.html) ### What are the signs it is failing? The usual sign is a low-voltage warning on the screen telling you to replace the 12V battery. A car that will not unlock or wake up is another. Source: [roadsumo.com](https://roadsumo.com/tesla-12v-battery-replacement/) ### How long does it last? Lead-acid 12V batteries in Teslas are commonly replaced every few years; one guide suggests every two to three years.
