The Tesla Cybertruck has hit the roads, immediately turning heads with its stainless steel body and heralding a major shift in electric vehicle (EV) power. Central to this futuristic truck is a battery system unlike any other from Tesla, blending new 4680 cell technology, a structural battery pack, vast power storage, and a groundbreaking dual-voltage electrical design.
People who might buy the truck, people who love EVs, or people who are simply curious need to know about the truck’s battery. People must understand the battery to know how the truck works. The following part will look closely at the Cybertruck’s power source. The following part will answer questions about the battery’s size, technology, price, and future.
The Tesla Cybertruck uses a large structural battery pack. The pack uses 4680 cells. The pack can hold about 123 kWh of usable power. The pack runs on an 800-volt system. The truck also has a new 48-volt low-voltage system. The new system replaces the old 12-volt battery. The combination aims for better efficiency, faster charging, and a stronger power supply for the truck’s high-tech features.
What is the Tesla Cybertruck Battery Size and Technology?
The Cybertruck’s battery is a marvel of engineering, primarily due to the 4680 cell technology. This is one of the most important secrets to the truck’s performance.
The 4680 Cell Advantage
The number 4680 tells about the cell’s size. The cell is 46 millimeters wide. The cell is 80 millimeters tall. These cells are much bigger than the 2170 cells. Other Tesla cars use the 2170 cells.
| Feature | 4680 Cell (Cybertruck) | 2170 Cell (Model Y/3) | Benefit for Cybertruck |
|---|---|---|---|
| Diameter | 46 mm | 21 mm | Higher energy density |
| Height | 80 mm | 70 mm | Higher power output |
| Design | Tabless | Tabbed | Reduced internal resistance, less heat |
| Manufacturing | Dry Electrode | Wet Electrode | Lower cost, faster production |
The tabless design changes things. Electricity travels a shorter path inside the cell. Design lowers internal resistance. Less heat comes out. Less heat allows faster charging and better performance.
Structural Battery Pack
The Cybertruck’s battery is a structural pack. The battery enclosure is an important part of the truck’s frame. Tesla makes the battery part of the structure. This improves the truck’s stiffness and safety in a crash. It also makes the truck lighter.
The total energy capacity of the Cybertruck’s battery pack is about 123 kWh. The big size of the battery is needed. It powers the heavy, all-wheel-drive truck. It also gives the truck a good driving range.
Pricing and Auxiliary Details
As of November 2025, the AWD Cybertruck starts around $79,990, and the Cyberbeast is about $99,990. Actual transaction prices vary depending on options and market adjustments.

Range and Performance: How Far Can the Cybertruck Go?
The official EPA range for the Cybertruck changes based on the trim level and tire choice.
- All-Wheel Drive (AWD): AWD Cybertruck can go about 340 miles on a full charge.
- Cyberbeast: Cyberbeast Cybertruck can go about 320 miles on a full charge.
These numbers use standard road tires. People who choose all-terrain tires will see a slightly lower range.
The Range Extender: A Brief History
Early in the Cybertruck’s development, Tesla offered an extra range extender battery. The battery would sit in the truck bed. It was meant to make the range more than 450 miles. Later, the company silently removed the option. The decision shows Tesla trusts the current 4680 battery pack’s power. Tesla is likely working to make the battery cells better. One report said the Cybertruck’s cells have 10% more energy.
Practical Tip: To get the most range, keep your tires full of air. Do not drive or speed up too fast. Use the “Chill” drive mode when you do not pull a trailer or carry a heavy load.
The Cybertruck’s Dual-Voltage System: 48V and 800V
The Cybertruck has two major electrical systems that are essential to its operation: the high-voltage system and the low-voltage system.
1. High-Voltage (HV) System: The 800-Volt Architecture
The main battery pack operates on an 800-volt nominal architecture. This is a significant upgrade from the 400-volt system used in most other EVs, including the Tesla Model S and Model 3.
Why 800 Volts?
1. Faster Charging: Higher voltage allows for lower current at the same power level. Lower current means less heat is generated in the charging cables and the battery itself, enabling faster charging speeds.
2. Lighter Wiring: Less current means you can use thinner, lighter wiring throughout the vehicle, which helps reduce the truck’s overall weight.
2. Low-Voltage (LV) System: The 48V Revolution
The shift from a regular 12-volt system to a 48-volt low-voltage system is a big change. The new system powers all the truck’s parts. These parts include the windows, the lights, the infotainment screen, and the steering.
The Cybertruck does not have a 12V battery. It uses a lithium-ion Tesla Cybertruck 48V battery instead. The change is a big improvement in how cars are built.
“The 48V architecture is a huge deal. It allows for smaller, lighter components and can handle the massive power demands of a modern truck like the Cybertruck much more efficiently than the old 12V standard.”
Tesla Cybertruck Battery Price and Replacement
One of the biggest concerns for any EV owner is the cost of replacing the high-voltage battery. While the Cybertruck is still new, we can estimate the Tesla cybertruck battery price based on industry trends and Tesla’s current pricing.
Estimated Replacement Cost
A complete change of a Tesla high-voltage battery pack costs from $15,000 to $25,000. The Cybertruck uses a big, special 4680 structural battery pack. The cost to replace the Cybertruck’s battery will likely be more. The price could be over $30,000 if the owner does not have a warranty.
| Component | Estimated Cost (USD) | Notes |
|---|---|---|
| Battery Pack | $20,000 – $30,000+ | Based on 123 kWh capacity and new 4680 technology. |
| Labor | $500 – $1,500 | Specialized labor is required for structural pack replacement. |
| Total Estimated | $20,500 – $31,500+ | This is an estimate and subject to change. |
Tesla Cybertruck Battery Replacement Warranty
The battery has a good warranty. The Tesla Cybertruck battery replacement warranty lasts for 8 years or 150,000 miles (240,000 km). The one that happens first decides when the warranty ends. The warranty also makes sure the battery keeps at least 70% of its ability to hold a charge during those years or miles.
Actionable Advice: To keep the battery safe and make it last:
- Do not always charge to 100%. Only charge fully if you must drive a long distance right away. Tesla says to charge to only 80% or 90% most days.
- Do not use the fast charger (Supercharger) all the time to charge your truck.
- Keep the truck plugged in when you can. This helps the battery system keep the cells even, even when the charge is low.
Conclusion
The Tesla Cybertruck’s battery is a major leap forward for EVs. By integrating the 4680 structural battery pack and a dual 800V/48V electrical architecture, Tesla has delivered a system that enhances efficiency, charging speed, and structural integrity. The Cybertruck’s power unit is a definitive benchmark for the next generation of electric trucks. Future owners can maximize the longevity of this groundbreaking technology by following simple charging advice and leveraging the robust 8-year warranty.
FAQs
What is the Cybertruck battery voltage?
The main high-voltage battery operates on an 800-volt nominal architecture. The low-voltage system, which powers accessories, operates at 48 volts.
How much does the Cybertruck battery weigh?
While Tesla has not released an official weight, estimates for the 123 kWh structural pack place its weight between 1,800 and 2,000 pounds (816 to 907 kg). The structural design helps to offset some of this weight by eliminating other structural components.
Can I get a Tesla Cybertruck battery upgrade?
Currently, there is no official Tesla cybertruck battery upgrade available. However, the modular nature of the 4680 cells means that as Tesla improves the cell chemistry (e.g., increasing energy density), future replacement packs or new vehicles could offer better performance or range without changing the physical size of the pack.
What is the Cybertruck price?
The starting Cybertruck price for the All-Wheel Drive version is around $79,990, and the high-performance Cyberbeast starts at around $99,990. Prices are subject to change and depend on configuration and options.
Where is the Cybertruck 12V battery location?
The Cybertruck does not have a traditional 12V lead-acid battery. It uses a 48V lithium-ion battery for its low-voltage needs. This 48V battery is typically located in the front trunk (frunk) area, though its exact placement is integrated into the vehicle’s architecture.
