Tesla Low-Voltage Battery Replacement
Battery support for your Tesla, with mobile replacement available for supported vehicles and locations.
Tell us your model, year, and location. We’ll help confirm the correct low-voltage battery and available service options before you book.
Why Tesla Battery Replacement Needs the Right Approach
Your Tesla’s low-voltage battery supports its electrical systems and is separate from the high-voltage battery that powers driving. The correct replacement depends on the vehicle’s model, build date, and installed battery type.
Some Teslas use a lead-acid low-voltage battery, while others use a lithium-ion system. These require different parts and procedures. We confirm compatibility and local service availability before arranging a replacement.
This service is for low-voltage auxiliary batteries. High-voltage traction-battery repairs and replacements are outside this service.
Tesla Models — Check Availability
Send us your vehicle details for a model-specific battery and service check:
- Tesla Model S
- Tesla Model 3
- Tesla Model X
- Tesla Model Y
Availability depends on the exact vehicle, battery specification, parts supply, and your service location. If your Tesla is not listed in online booking, send a battery request or call 866-709-2116.
When to Have Your Tesla’s Low-Voltage Battery Checked
If your vehicle displays a low-voltage battery warning or a message recommending battery replacement, arrange an assessment and follow the instructions displayed by your vehicle.
Share the exact warning message with our team. A warning or electrical issue does not always mean the battery alone needs replacement, so compatibility and the service needed must be confirmed first.
The MobileBattery Process
Share Your Vehicle Details
Provide your Tesla model, year, location, and any battery warning messages. Our team may request the VIN or battery information to confirm fitment.
Confirm the Battery and Service
We check the battery specification, parts availability, service coverage, and price before you book.
Arrange Onsite Replacement
Where service is available, arrange an appointment at your home, workplace, or another suitable location.
Installation and Final Checks
The replacement follows the procedure appropriate to the confirmed vehicle and battery, with final checks and old-battery handling discussed as part of your service.
Tesla Low-Voltage Battery Types
Tesla low-voltage systems are not one-size-fits-all. Do not select a replacement using a generic battery group size or model year alone.
- Lead-acid systems: the replacement must match the vehicle’s required specification.
- Lithium-ion systems: the battery and replacement procedure must be verified for the specific vehicle.
For reference, Tesla’s Model 3 owner’s manual explains why the installed low-voltage battery type must be confirmed before replacement.
