The small battery that makes a Tesla look dead
We come to your Tesla in Safety Harbor and replace the 12-volt low-voltage battery that runs the screen, handles and computers. We check the VIN first, so you know before we arrive whether yours is a 12-volt or 16-volt lithium car. Call (813) 568-9904 or text the year, model and VIN.
Tesla battery calls in Safety Harbor
A Safety Harbor Tesla that will not unlock in the driveway, in Safety Harbor or close by, is usually a quick visit for us when it has the 12-volt lead-acid battery. We check the VIN by text first, so we only come out when we can fix it.
Safety Harbor is in Pinellas County. We cover it along with Oldsmar, Dunedin and Westchase.
12-volt or lithium: check before we come
Tesla changed the low-voltage battery over the years, so two cars of the same model can need different parts. Roughly:

|---|---|---|
| Model S | 2012–2020: 12V lead-acid (AGM) | 2021 on (refresh): lithium-ion, about 15.5–16V |
| Model X | 2016–2020 model years: 12V lead-acid | 2021 on (refresh): lithium-ion, about 15.5–16V |
| Model 3 | Built through about 2021: 12V lead-acid | About 2022 on, incl. 2024+ Highland: lithium-ion (16V or 14.4V) |

Questions we get
Can you replace my Tesla low-voltage battery at home in Safety Harbor?
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 Safety Harbor, FL. Call (813) 568-9904.
Do you replace the lithium low-voltage battery on newer Teslas in Safety Harbor?
Normally that goes through Tesla. It is a Tesla part designed for a long life. Send the VIN and we tell you which one you have before anyone drives out.
Is my Tesla a 12-volt or 16-volt car?
It depends on the build date, not just the year. Look under Controls > Software > Additional Vehicle Information, or text us the VIN.
Will a jump start fix a dead Tesla?
External 12-volt power can wake the car enough to open the frunk. If the battery has failed, it still needs to be replaced.
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.
