Tesla calls in Largo come from the same crew that covers Clearwater, Seminole and Pinellas Park.
Tesla low-voltage battery types
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) |
| Model Y | Built through about 2021: 12V lead-acid | About 2022 on, incl. 2025+ redesign: lithium-ion (16V or 14.4V) |

Straight answers on what we fix
- 12-volt lead-acid (older Model S, X, 3 and Y): replaced on site.
- 16-volt (or 14.4-volt) lithium-ion low-voltage battery: Tesla designs these to last much longer, and they are a Tesla part. If yours has one, we tell you before we drive out, and Tesla Service may be the right call.
- High-voltage drive pack: not part of this service.
- Cybertruck: uses a 48-volt low-voltage system. That is a Tesla Service job, not ours.

Questions we get
Do you replace Tesla 12V batteries in Largo?
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 Largo, FL. Call (813) 568-9904.
Do you replace the lithium low-voltage battery on newer Teslas in Largo?
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.
