📋 What we found
For your Tesla Model 3 EV we found 5 compatible batteries. This list includes 1 Start-Stop battery, 2 conventional batteries (non Start-Stop) and 2 auxiliary batteries.
⚡ Starter or auxiliary battery
We detected an auxiliary battery among the compatible ones. The auxiliary is NOT your main car battery: it is a smaller secondary battery that powers sensitive electronics. Don't mix them up when buying. Usually what fails is the starter battery (the main one), but the auxiliary can also fail. If your vehicle shows intermittent electronic errors but starts fine, it may be the auxiliary; if cranking is weak, it is usually the starter battery.
Does your Tesla Model 3 EV have a Start-Stop system? It shuts the engine off at short stops (traffic lights, jams) and restarts it automatically when you release the brake/clutch. If your dashboard has an "A-OFF" button or an engine icon with a circular arrow, it has it.
How do I know if my car has Start-Stop?
What happens if I fit a conventional battery in a Start-Stop car?
🔋 Technology (AGM / EFB)
✓ All Start-Stop batteries in the list are AGM. If your current battery is AGM, this is the right replacement. If it is EFB, an AGM is also a valid upgrade, but on cars with battery management (BMW, Mercedes, VAG group…) it must be registered and coded for the new technology with a diagnostic tool; otherwise the car keeps charging it as an EFB.

Start-Stop & high energy demand batteries
AGM or EFB battery for start-stop vehicles and for cars with high energy demand (many electrical consumers, frequent starts). More charge cycles, better charge recovery and longer service life.
Does your car have Start-Stop?
Start-Stop switches the engine off at traffic lights. If your car has it, it needs an AGM or EFB battery.
There are no batteries of that type for this engine. Try "Show all" or message us.
Compare the technologies available for your car
A higher technology withstands more charge and discharge cycles, according to manufacturers. If your car has Start-Stop, it needs EFB or AGM.

Frequently asked questions
- Yes, you can install a higher capacity (Ah) battery as long as the physical dimensions fit your Tesla Model 3 EV battery compartment and the positive terminal position matches.
- The Tesla Model 3 Ev requires a battery with the correct capacity (Ah) and Cold Cranking Amps (CCA) for this engine. Compatible batteries offer 38 Ah, 460 A (CCA), 12 V, case 51R (BCI). Browse the compatible battery list below.
- The exact Ah rating for the Tesla Model 3 Ev depends on the vehicle's original electrical consumers. Compatible batteries offer 38 Ah, 460 A (CCA), 12 V, case 51R (BCI). Use our finder for a precise recommendation.
- You need the make, model and engine. If your car has Start-Stop (the engine switches off at traffic lights), it needs an EFB or an AGM battery, depending on what it came with: if it has an AGM, fit another AGM; if it has an EFB, another EFB or an AGM. On cars with battery management (BMW, Mercedes, VAG group…), moving from EFB to AGM requires coding the new battery. Without Start-Stop, a conventional battery is fine, or an EFB or AGM if you want a longer life.
- A conventional (lead-acid) battery is for cars without Start-Stop. An EFB is a reinforced conventional battery for basic Start-Stop. An AGM offers the highest performance and is fitted as standard on cars with advanced Start-Stop, regenerative braking or high electrical demand. Replacement rule: an AGM only with another AGM; an EFB with another EFB or an AGM; a conventional battery with any of the three. Never move down in technology.
- Use the search tool by selecting your vehicle's make and model. Our system automatically filters compatible part numbers verified by our technicians. If you have any questions, contact us via WhatsApp.
- All our batteries come with the legal guarantee provided by consumer law against manufacturing defects. If a battery has a manufacturing defect, it will be replaced at no cost to the user.
- Under normal circumstances, batteries usually arrive within 1 to 2 days of ordering. However, there are some cases where delivery may take a little longer: peak seasons (Black Friday, Christmas, etc.), palletized shipments, occasional stock shortages, etc.
- In mainland Spain delivery takes 24-48 working hours if you order before 6:00 pm (Monday to Friday) and the battery is in stock; mainland Portugal takes 1 to 4 working days, the Balearic Islands 2 to 5 working days and other EU destinations 4 to 7 working days. Batteries are shipped fully charged and ready to install.
- It depends on the version. If your Tesla Model 3 EV has Start-Stop (the engine switches off by itself at traffic lights) it needs an EFB or AGM battery; if not, a conventional one. To check, look for an "A" or "A-OFF" button near the gear lever, or read the label on your current battery: if it says EFB, AGM or Start-Stop, choose that technology.
