What Battery Does Tesla Use – Comprehensive Guide – 2025!

Tesla has become synonymous with electric cars — but behind every Tesla is a complex battery system that defines range, cost, safety and longevity. If you’re asking “What battery does Tesla use?”

Tesla uses different lithium-ion chemistries and cell formats depending on model and factory, Historically nickel-based cells (NCA/NMC) for high energy and performance, lithium-iron-phosphate (LFP) for lower-cost standard-range cars, and the newer large “4680” cylindrical cells as Tesla scales its own designs.

This article explains, in plain English and with clear sections, the types of cells and chemistries Tesla uses today, how they differ, why Tesla chooses them for particular models, and what that means for owners.

Battery basics: cells, modules, packs — what those words mean

• Cell: the smallest unit (like a single AA battery but advanced). Tesla has used cylindrical cells (18650, 2170, 4680) and prismatic pouch/prismatic cells in some packs.
• Module: a group of cells wired together. Older Tesla packs used multiple modules; Tesla’s newer designs reduce module count or remove modules entirely.
• Pack: everything together — cells, cooling, electronics (BMS), and the outer casing that goes under the car.

Why it matters: the cell chemistry determines energy density, cost, safety and cycle life; the pack design determines manufacturability and thermal control. 

The main chemistries Tesla uses today:

Nickel-Cobalt-Aluminum (NCA) / Nickel-Cobalt-Manganese (NCM or NMC):

• Where used: Historically in higher-range and performance Tesla cars (e.g., many Model S, Model X, early Model 3/Y long-range builds).
• Strengths: high energy density (more range per kg), good power for fast acceleration.
• Trade-offs: more expensive, uses cobalt (ethical/supply concerns), typically slightly faster degradation under aggressive use than LFP. 

Lithium-Iron-Phosphate (LFP):

• Where used: Tesla moved many standard-range Model 3 and Model Y cars to LFP (especially cars built in China or vehicles designated as “Standard Range” in many markets). Some entry-level Teslas globally now default to LFP.
• Strengths: very safe (stable chemistry), long cycle life (more charge cycles before capacity drops noticeably), lower cost (no cobalt), can often be charged to 100% regularly without the same degradation penalties as nickel chemistries.
• Trade-offs: lower energy density — so for the same weight you get less range, which is why performance/long-range cars still use nickel cells. 

4680 “tabless” cells (Tesla’s new form factor):

• What they are: a physically larger cylindrical cell (46 mm × 80 mm) designed by Tesla to reduce pack complexity and improve manufacturing economics. They are often discussed along with new manufacturing techniques (dry electrode coating, tabless architecture).
• Why Tesla is excited: potential for lower cost per kWh, improved thermal behaviour and simpler pack designs that increase energy per pack.
• Reality check: manufacturing ramp-up and yield challenges have been reported; Tesla is gradually increasing 4680 use in certain models (e.g., Cybertruck prototypes, some US-made Y variants) while still relying on 2170 or other cells elsewhere.

Which battery is in my Tesla?

There’s no single answer — it depends on model, trim, factory and model year. General rules:

• Standard-range Model 3 / Model Y: increasingly LFP (especially vehicles built in China and many RWD variants).
• Long-range and Performance trims: usually nickel-based (NCA or NMC) 2170 cells, though factory and VIN location can change this. 
• Newer US-made models and prototypes (Cybertruck, select Model Y): may use 4680 cells in the pack for certain builds; availability varies by factory. 

If you want to know exactly, Tesla service or VIN-based lookup tools (and enthusiast databases) can often reveal pack details for your VIN or build date.

How chemistry affects ownership: range, charging, and longevity?

Range:

• Nickel-based cells deliver higher range for the same pack weight. That’s why long-range/performance models typically use NCA/NMC. LFP packs give less range but are cost-effective for city commuters.

Charging behaviour:

• LFP is more tolerant of high state-of-charge (SOC); Tesla has allowed some LFP cars to set the daily charge limit to 100% because the chemistry is less stressed at full charge. Nickel-based packs usually have Tesla-recommended daily limits around 80–90% for long life, reserving 100% only for trips.

Longevity and degradation:

• LFP typically cycles better (more full charge cycles with less capacity loss). Nickel chemistries can deliver more range up front but may, under aggressive charge/discharge patterns, show faster calendar or cycle degradation. Actual life depends heavily on how you charge, climate, and software management.

Tesla’s vertical integration: why Tesla builds its own cells

Tesla’s long-term strategy is to reduce cost and control supply by designing its own cells (4680 and future variants) and optimizing pack and factory integration. The company has invested in “dry electrode” processes and new cell designs to lower manufacturing steps and reduce raw-material sensitivity. 

This is why you’ll see a mix: some cars use supplier cells (Panasonic, LG, CATL) while others use Tesla-designed cells as they scale production. Scaling the 4680 and newer chemistries is a multi-year effort with technical and yield challenges.

Safety and recycling:

• Safety: LFP is generally the safest lithium chemistry (less tendency for thermal runaway). Tesla’s packs include active thermal management and safety software regardless of chemistry.
• Recycling: As EVs grow, battery recycling is a major industry focus. Nickel-rich packs require cobalt recovery; LFP packs avoid cobalt but still need lithium/iron/phosphate recovery. Tesla and partners are investing in closed-loop recycling to reclaim materials and reduce supply risks.

What about the future — solid-state and beyond?

Most industry forecasts see incremental lithium-ion improvements (new cathodes, manufacturing refinements like dry coating) during the 2020s; solid-state batteries may arrive later with big leaps in energy density and safety. 

Tesla has signalled multiple new cell designs in development for different vehicle types (including an eventual robotaxi battery), but widespread commercial rollout of fundamentally new chemistries will take time. For now, expect improvements in cost and performance mainly from cell format changes (4680), better manufacturing, and supply agreements. 

Practical tips for Tesla owners (charging & care by battery type):

• If your Tesla has LFP: you can comfortably set daily charge limits near 100% if Tesla’s UI or documentation allows it — LFP tolerates full charge better. Still, avoid extremely high-temperature storage at full SOC for long periods.
• If your Tesla has nickel-based cells (NCA/NMC/2170): follow Tesla’s recommended daily limit (often ~80–90%), and charge to 100% only before long drives. Avoid frequent fast charging extremes when possible. 
• General: keep software updated — Tesla’s battery management and thermal controls improve over time via OTA updates.
