Tesla Battery Replacement
While Teslas are best known for their high-voltage lithium-ion drive batteries, each model also relies on a low-voltage auxiliary battery to power essential functions like lights, door locks, and onboard electronics. If you've received a battery warning on your screen or noticed unusual electrical behavior, it may be time to replace your Tesla’s auxiliary battery.

Tesla Battery FAQs
Yes. Most Teslas are equipped with a 12-volt auxiliary battery to power systems like lights, sensors, and locks. Some newer models have transitioned to a 16-volt lithium version. This battery works independently from the high-voltage drive battery.
Tesla auxiliary batteries generally last 3 to 5 years. If your vehicle displays a low-voltage battery warning or starts behaving oddly when parked, it's a good idea to have the battery inspected and replaced if needed.
