TESLA 12V · LOW VOLTAGE
Tesla 12V Battery Replacement in Tampa
Tesla dead, will not unlock, or showing a low-voltage warning? It is usually the small battery, not the drive pack. We replace 12-volt lead-acid batteries where the car is parked.

- No trip we cannot fix
Tesla will not wake up? Start here
We replace Tesla 12-volt low-voltage batteries at your location across Tampa. Send the VIN or call (813) 568-9904. We confirm which battery your car has before anyone drives out, so you are not paying for a trip that cannot fix it.
Here is the honest version: older Teslas use a 12-volt lead-acid battery we can replace on site. Newer builds use a 16-volt (or 14.4-volt) lithium-ion low-voltage battery, which is a Tesla part. If yours has one, we will say so up front.
What the Tesla low-voltage battery does
Every Tesla has two batteries: the big high-voltage pack that drives the car, and a small low-voltage battery that runs the screen, door handles, locks, and the computers that switch the drive pack on. When the small one fails, the car can look completely dead with plenty of range left.
What we can and cannot do
- 12-volt lead-acid: replaced on site.
- 16-volt or 14.4-volt lithium-ion: a Tesla part designed for a much longer life. If the VIN shows one, we tell you before we drive out; usually Tesla Service is the right call.
- High-voltage drive pack: not part of this service.
- Cybertruck: 48-volt low-voltage system, a Tesla Service job.

Warning signs

- The car goes completely dark after sitting, even with plenty of range
What the job involves
- VIN check to confirm the battery type and part.
- If the car is dead, we open the frunk with external power on the release leads.
- Proper power-down, covers off, battery swapped.
- Car woken up and checked for alerts before we leave. Old battery recycled.
12-volt or 16-volt lithium? It depends on the build
Tesla moved from 12-volt lead-acid to lithium-ion low-voltage batteries starting with the 2021 Model S and X refresh, then Model 3 and Model Y from about the 2022 model year. Check yours under Controls > Software > Additional Vehicle Information.
| Model | We can replace on site | Tesla part (we tell you up front) |
|---|---|---|
| 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) |
| Cybertruck | n/a | 48V low-voltage system (Tesla Service) |

Questions we get
Do you replace Tesla 12V batteries in Tampa?
Yes, on Teslas with the 12-volt lead-acid battery, at your home, work or wherever the car is parked in Tampa. Call (813) 568-9904.
Can you replace the 16-volt lithium battery?
It is a Tesla part. If your car has one, we tell you before we come out, and in most cases Tesla Service is the right route.
How do I check which battery my Tesla has?
Controls > Software > Additional Vehicle Information on the touchscreen, or send us the VIN.
My Tesla is completely dead. Can you still get in?
Yes. Tesla provides a way to open the frunk with external 12-volt power, and that is how we reach the battery.
Is it the big battery?
Usually not. A car that will not wake up with range showing in the app is a classic low-voltage battery failure. We do not service the high-voltage pack.
Do you work on Cybertruck?
No. Cybertruck uses a 48-volt low-voltage system and is a Tesla Service job.
Which Teslas have a 12-volt lead-acid battery?
Model S through the 2020 model year, Model X through 2020, and Model 3 and Model Y built through about 2021. Later builds use a lithium-ion low-voltage battery.
