Unsure about your Tesla's battery type? Don't worry, you're not alone! Many Tesla owners are curious about what kind of battery powers their electric vehicle, especially with the different chemistries and cell formats Tesla has used over the years. Knowing your battery type can help you understand its characteristics, optimal charging practices, and even its estimated lifespan. This comprehensive guide will walk you through various methods to determine your Tesla's battery type.
Step 1: Engage with Your Tesla's Inner Brain (Software Check)
Let's start with the easiest and most accessible method: checking directly through your Tesla's infotainment system. This is often the most reliable way to identify battery chemistry for newer models, especially the Model 3 and Model Y.

| How To Check Tesla Battery Type |
Sub-heading 1.1: The Charging Screen Clue
This method is particularly useful for distinguishing between Nickel-based (NCA/NCM) and Lithium Iron Phosphate (LFP) batteries.
Get Charged Up: First, ensure your Tesla is plugged into an AC charger. It doesn't need to be a Supercharger; any standard AC charging will do.
Navigate to Charging: On your Tesla's central touchscreen, touch the car icon (usually at the bottom left), then select "Charging."
Observe the Charge Limit Slider:
If you see two sliders labeled "Daily" and "Trip," it's a strong indicator that your Tesla has a Nickel-based (NCA or NCM) battery. These batteries generally benefit from being charged to 80-90% for daily use to maximize longevity.
If you see a single slider ranging from 50% to 100%, and a recommendation to "keep your charge limit at 100% and charging fully once a week," you most likely have a Lithium Iron Phosphate (LFP) battery. LFP batteries prefer being charged to 100% regularly to keep their state-of-charge calibration accurate.
Sub-heading 1.2: The "Additional Vehicle Information" Deep Dive
This method provides a more direct statement about the battery chemistry.
Access Controls: From the main screen, touch "Controls" (the car icon).
Go to Software: Select the "Software" tab.
Find Additional Vehicle Information: Look for and tap on "Additional Vehicle Information."
Read the Battery Type: If your Tesla is equipped with an LFP battery, it will often explicitly state "High Voltage Battery type: Lithium Iron Phosphate" here. If it doesn't specify a type, it's generally a Nickel-based battery (NCA or NCM).
Step 2: Uncover the Physical Evidence (Battery Pack Sticker) ️
For some older models, especially the Model S and Model X, looking for a physical sticker on the battery pack can provide insights into the battery pack version. While this might not directly state the chemistry, it can indicate upgrades or generations of the battery.
Sub-heading 2.1: Locating the Sticker
This method requires a bit of maneuvering and a good flashlight!
Tip: Read once for gist, twice for details.
Park Safely: Ensure your Tesla is parked on a flat, safe surface, ideally with enough clearance to look underneath. Always prioritize safety when looking under your vehicle.
Get Low: For Model S and Model X, the battery pack information sticker is often found on the front right side of the battery pack, visible when looking from just behind the front right (passenger side) wheel. You might need to lie down or use a creeper to get a good view.
Snap a Picture: Use your phone to take a clear picture of the sticker. It will contain part numbers and potentially a "version" letter (like A, B, or D for Model S/X packs).
Sub-heading 2.2: Deciphering the Sticker (Model S/X Specifics)
While not a direct chemistry indicator, the battery pack version can hint at its characteristics.
Model S Battery Packs (A, B, D, E): Early Model S battery packs (A and B) had differences in cooling systems, affecting Supercharging speeds. Newer versions (D and E) often support faster charging. This indicates an evolution of the same core NCA chemistry rather than a different chemistry entirely.
Part Numbers: The sticker will also show a part number. You can sometimes cross-reference these part numbers online (e.g., on Tesla community forums or wikis) to find more details about the specific battery pack.
Step 3: Decode Your VIN (Vehicle Identification Number)
Your Tesla's VIN is a treasure trove of information, and certain digits can sometimes provide clues about the battery type and other vehicle attributes.
Sub-heading 3.1: Finding Your VIN
Your VIN is easily accessible:
Touchscreen: Go to "Controls" > "Software" on your Tesla's touchscreen.
Dashboard: Look at the top of the dashboard through the windshield on the driver's side.
Door Pillar: Open the front passenger door and check the product plate on the door pillar.
Sub-heading 3.2: Interpreting VIN Digits for Battery Clues
While not always a definitive indicator of chemistry for every model and year, certain VIN digits can provide insights:
Digit 7: This digit is often linked to the vehicle's battery type (though not necessarily battery size). For example, "E" might indicate a Lithium-ion (NMC/NCA) battery, while "F" might suggest a Lithium Iron Phosphate (LFP) battery. However, this can vary by production year and factory.
Digit 8: This digit typically relates to the motor/drive combination and power rating. In some cases, specific codes here might be indirectly associated with a particular battery setup.
Factory Code (Digits 1-3) combined with Model/Year: Knowing where your Tesla was manufactured (e.g., Shanghai, Fremont, Berlin, Austin) and its model year can help narrow down the likely battery type, as Tesla has shifted battery suppliers and chemistries for different production locations and models over time. For example, many Standard Range Model 3s and Model Ys produced in China and Germany since 2021 are equipped with LFP batteries.
Step 4: Consult the Experts (Tesla Service Center)
When in doubt, your local Tesla Service Center can provide the most accurate and definitive information about your vehicle's battery type.
QuickTip: Keep going — the next point may connect.
Sub-heading 4.1: Scheduling an Appointment
Use the Tesla App: The easiest way to schedule service is through the Tesla app.
Select "Service" then "Battery & Charging": Navigate to the service section and choose a relevant category like "Battery & Charging" or "Range."
Describe Your Concern: You can simply state that you'd like to know your vehicle's exact battery chemistry or type.
Remote Diagnostics: Tesla often performs remote diagnostics before your appointment, which might already reveal the information they need.
Sub-heading 4.2: Running a Battery Health Test
While not directly for identifying the type of battery chemistry, a Battery Health Test can be performed through the Tesla service menu (sometimes requiring AC charging for up to 24 hours). This test assesses the battery's energy retention compared to when it was new and can be a good indication of overall battery health. If there's any concern with the battery, the service center will provide detailed information.
Step 5: Understanding Tesla Battery Types and Their Implications
Tesla primarily uses different types of Lithium-ion batteries, but the chemistry and cell format have evolved. Here's a brief overview:
Sub-heading 5.1: Key Battery Chemistries
NCA (Nickel-Cobalt-Aluminum): Historically used in Model S, Model X, and many Long Range/Performance Model 3 and Model Y vehicles. These batteries generally offer high energy density, allowing for longer range.
NCM (Nickel-Cobalt-Manganese): Similar to NCA, NCM batteries are also a nickel-based chemistry used in some Tesla vehicles, particularly those produced in Gigafactory Berlin and Shanghai (e.g., some Model Y trims). They share similar charging characteristics to NCA.
LFP (Lithium Iron Phosphate): Increasingly used in Standard Range Model 3 and Model Y vehicles, particularly those manufactured in China and Germany. LFP batteries are generally more robust, can be charged to 100% regularly without significant degradation, are less susceptible to thermal runaway, and are more cost-effective as they are cobalt-free.
Sub-heading 5.2: Cell Formats
18650 Cells: Cylindrical cells (18mm diameter, 65mm length) historically used in the Roadster, Model S, and Model X.
2170 Cells: Larger cylindrical cells (21mm diameter, 70mm length) introduced with the Model 3 and still widely used in Model 3 and Model Y.
4680 Cells: A newer, larger cylindrical cell (46mm diameter, 80mm length) with a "tabless" design. These are being produced at Gigafactory Texas for some Model Ys and Cybertrucks, promising improved power, range, and manufacturing efficiency.
Prismatic Cells: Flat, rectangular cells, primarily used for LFP batteries.
Knowing your battery type helps you understand the manufacturer's recommendations for charging and general care, contributing to the longevity and optimal performance of your Tesla.
