The small battery that makes a Tesla look dead
Tesla will not wake up in Dunedin? It is usually the small low-voltage battery, not the drive pack. We replace 12-volt lead-acid batteries on Model S, X, 3 and Y where the car is parked. Call (813) 568-9904 or text the year, model and VIN.
Tesla battery calls in Dunedin
Humidity and salt near Edgewater Drive, Highlander Park and the Causeway to Honeymoon Island in Dunedin speed up corrosion on small connectors. On a Tesla that matters, because the low-voltage system has to be healthy for the car to wake up and close its high-voltage contactors.
Tesla calls in Dunedin come from the same crew that covers Palm Harbor & East Lake, Clearwater and Safety Harbor.

What we do on Teslas in Dunedin, and what we do not
- Older Teslas with a 12-volt lead-acid battery: we replace it where the car is parked.
- Teslas with the lithium-ion low-voltage battery: we will not send a truck for a part we cannot fit. You will hear that from us before we come.
- We do not touch the high-voltage pack, and Cybertruck low-voltage work goes to Tesla.
Is it the 12-volt? Signs we hear about in Dunedin
- The screen goes black or reboots, and the car will not shift into gear
- Model X falcon-wing doors act up before anything else does
- The car goes completely dark after sitting, even with plenty of range
- A low-voltage or "12V battery" alert on the touchscreen
How a Tesla 12-volt swap goes
- We check the VIN (or Controls > Software > Additional Vehicle Information on the screen) to confirm the battery type.
- If the car is dead, we open the frunk using the external-power leads Tesla provides for that.
- We power the car down the right way, remove the covers, and swap the 12-volt battery.
- The car is reconnected, woken up and checked for alerts before we leave. The old battery is recycled.

Questions we get
Can you replace my Tesla low-voltage battery at home in Dunedin?
Yes, on Teslas with the 12-volt lead-acid battery: Model S and X through 2020 and earlier Model 3 and Model Y. We come to you in Dunedin, FL. Call (813) 568-9904.
My Tesla has the 16-volt lithium battery. Can you replace it?
Those are Tesla parts built to last much longer than the old 12-volt. If the VIN shows a lithium low-voltage battery, we tell you before we come out, and in most cases Tesla Service is the right route.
How do I know which low-voltage battery my Tesla has?
On the touchscreen, go to Controls > Software > Additional Vehicle Information. Or send us the VIN and we check.
My Tesla is dead in a Dunedin garage. What do I do?
Leave it where it is and call us with the location and VIN. With external power we can open the frunk and, on 12-volt cars, replace the battery right there.
Do you work on the high-voltage battery or Cybertruck?
No. We do not service the drive pack, and Cybertruck's 48-volt system is a Tesla Service job.
