| How To Know What Battery My Tesla Has |
1.1 Navigate to the Charging Menu
-
Plug in your Tesla to any AC charger. This can sometimes trigger specific battery information to appear, especially for LFP (Lithium Iron Phosphate) batteries.
-
On your Tesla's large infotainment screen, tap the car icon (usually in the bottom left corner) to access the vehicle controls.
-
Then, navigate to the "Charging" section.
1.2 Observe the Charging Limit Screen
-
Once in the Charging menu, you'll see options to "Set Limit" for your charging. This is where the magic happens!
-
For LFP Batteries: If your Tesla has an LFP battery, you will likely see a recommendation to keep your charge limit at 100% and charge fully once a week. The slider for the charge limit may also simply show percentages (e.g., 50%, 100%) without "Daily" or "Trip" labels. This is a strong indicator of an LFP battery, as they benefit from frequent full charges for accurate calibration.
-
For NCA/NCM Batteries: If your Tesla has an NCA (Nickel-Cobalt-Aluminum) or NCM (Nickel-Cobalt-Manganese) battery, you'll typically see "Daily" and "Trip" labels on the charging limit screen. Tesla generally recommends charging these batteries to around 80-90% for daily use to optimize longevity, reserving 100% for longer trips.
1.3 Delve Deeper into "Additional Vehicle Information"
-
For some newer Model 3 and Model Y trims, or for a more definitive answer, you can also check under the "Software" section.
-
Go to Controls > Software > Additional Vehicle Information.
-
Here, you might find a direct mention of "High Voltage Battery type: Lithium Iron Phosphate" if your vehicle is equipped with an LFP battery.
Step 2: Decode the Clues from Your Charging Habits and App
Your Tesla's charging behavior and the information displayed in the mobile app can also offer strong hints about its battery type.
2.1 The Tesla Mobile App
QuickTip: Take a pause every few paragraphs.
-
Open the Tesla mobile app on your smartphone.
-
Just like on the car's screen, the app will often reflect the same charging recommendations and options. If you see the 100% weekly charge recommendation, it's another confirmation of an LFP battery.
-
The app's main screen displays the current battery capacity, predicted range, and battery percentage, giving you a general overview.
2.2 Charging Recommendations & Patterns
-
LFP Battery Behavior: If your Tesla encourages you to charge to 100% regularly (at least once a week) for battery calibration, it's almost certainly an LFP battery. This is because LFP batteries have a flatter voltage discharge curve, making it harder for the Battery Management System (BMS) to accurately estimate the remaining charge without occasional full charges.
-
NCA/NCM Battery Behavior: If your Tesla's default or recommended daily charge limit is around 80-90%, and only suggests 100% for longer trips, you likely have an NCA or NCM battery. These chemistries prefer to stay within a middle charge range to reduce stress and extend their lifespan.
Step 3: Unravel the Mystery with Your VIN (Vehicle Identification Number) ️♀️
Your Tesla's VIN holds a wealth of information, and certain digits can sometimes indicate the battery type. While not always a direct one-to-one correlation for chemistry, it can offer insights, particularly for newer models.
3.1 Locate Your VIN
-
Your VIN is a 17-character alphanumeric code unique to your vehicle. You can find it in several places:
-
On the driver's side dashboard, visible through the windshield.
-
On a sticker in the driver's side door jamb.
-
In the "Software" section of your Tesla's infotainment screen.
-
In your Tesla app, under your vehicle's details.
-
On your vehicle registration or insurance documents.
-
3.2 Decoding Specific VIN Digits
-
Digit 7: This digit is a vehicle attribute linked to the battery type (though not always battery size) and charger.
-
An 'E' can sometimes indicate a Lithium-Ion (NCA/NCM) battery, especially for cars produced in Shanghai. If digit 8 is 'S', it might signify a BYD LFP battery for non-Shanghai cars. Otherwise, 'E' broadly means "Electric."
-
An 'F' often signifies an LFP battery. If digit 8 is 'S', the battery might be from CATL.
-
Other letters like 'H', 'S', or 'V' can indicate specific NMC/NCA battery capacities.
-
-
Digit 8: This digit typically relates to the motor/drive combination and power rating, but in conjunction with digit 7, it can sometimes offer further clues about the battery supplier or type (e.g., 'S' for BYD LFP or CATL LFP).
Important Note: VIN decoding can be complex and sometimes not entirely straightforward, as Tesla's manufacturing and battery sourcing can evolve. For the most accurate interpretation, cross-reference with other methods. Online VIN decoders can also be helpful, but use them as a guide, not a definitive source, without other confirmations.
Step 4: Physical Inspection (For the Adventurous Souls)
For some older Model S/X vehicles, or if you're really curious, you might find a sticker directly on the battery pack.
4.1 Locate the Battery Pack Sticker
Tip: Context builds as you keep reading.
-
For some Model S and Model X vehicles, particularly older ones, you might find a sticker on the front corner of the battery pack, often visible from behind the front tire in the wheel well on the driver's side.
-
You might need to lay down and get your head in there, or use your phone's camera to snap a picture.
4.2 Deciphering the Sticker
-
This sticker can provide the part number and sometimes the battery size in kWh. While it may not directly state the chemistry (LFP, NCA, NCM), the kWh size can indirectly tell you a lot, as LFP batteries tend to be found in standard range models with smaller capacities, while higher capacities often indicate NCA/NCM.
-
For example, an 85 kWh or 100 kWh pack would almost certainly be NCA.
Disclaimer: Attempting a physical inspection under your car should be done with caution and only if you are comfortable and safe doing so. Never attempt to open or tamper with the battery pack itself. High voltage systems should only be handled by trained technicians.
Step 5: Consult the Experts (Tesla Service Center)
When in doubt, or if you want absolute confirmation, the most reliable source is always Tesla directly.
5.1 Schedule a Service Appointment
-
You can schedule a service appointment through your Tesla mobile app.
-
In the service request, you can explain that you'd like to confirm the specific battery chemistry of your vehicle.
5.2 Speak to a Service Advisor
-
Tesla service technicians have access to detailed specifications for your specific vehicle based on its VIN and production details. They can definitively tell you the battery type and chemistry installed in your car.
-
While battery replacements are rare, they can also perform a comprehensive battery health check if you have concerns about degradation.
Understanding Tesla Battery Types: A Quick Overview
Tesla has primarily used a few key battery chemistries and cell formats over the years:
-
NCA (Nickel-Cobalt-Aluminum): Historically used in many Model S, Model X, and early Long Range/Performance Model 3 and Y vehicles. Known for high energy density, offering longer range and higher power output. Generally recommended to charge to 80-90% for daily use.
-
NCM (Nickel-Cobalt-Manganese): Similar to NCA, also offers good energy density. Used in some Model 3 and Model Y vehicles, particularly those built in Gigafactories outside the US (e.g., Shanghai, Berlin). Shares similar charging recommendations with NCA.
-
LFP (Lithium Iron Phosphate): Increasingly used in Standard Range Model 3 and Model Y vehicles since late 2021/early 2022. LFP batteries are more durable, less prone to thermal runaway, and are generally cheaper to produce. A key characteristic is their recommendation to be charged to 100% regularly for accurate range estimation and improved longevity. They have a slightly lower energy density compared to NCA/NCM, meaning a given pack size might offer less range.
-
4680 Cells: Tesla's newer, larger cylindrical cells (46mm diameter, 80mm length) are being produced for the Cybertruck and some newer Model Ys (especially from Giga Texas). These can utilize different chemistries, including NCM, and are designed to be part of a "structural battery pack."
Knowing which battery you have helps you follow Tesla's recommended charging practices, maximizing your vehicle's longevity and performance!
