Panasonic Ncr21700t Datasheet Jun 2026

Preferred by hobbyists requiring extreme runtime and high lumens. 6. Safety Guidelines and Handling

At a standard , the voltage drops smoothly from 4.2V, holding a flat plateau around 3.6V for the majority of the cycle, before dropping sharply as it approaches the 2.5V cut-off.

Charging the cell to 4.1V instead of 4.2V reduces voltage stress and can double the cycle life.

Delivers more watt-hours per kilogram compared to standard 18650 cells.

Typically ranges between 12mΩ and 18mΩ. panasonic ncr21700t datasheet

The Panasonic NCR21700T is a high-performance, industrial-grade lithium-ion cell that has become a benchmark in the energy storage and electric mobility industries. Known for its optimal balance of energy density, safety, and reliability, understanding its technical specifications is crucial for engineers, product designers, and battery enthusiasts alike.

Used in solar backup walls and uninterruptible power supplies (UPS) due to its predictable cycle life.

Cordless drills, high-torque impact wrenches, and outdoor power gear benefit from the sustained discharge rate.

The "NCR" prefix in Panasonic's nomenclature signifies the use of Nickel-Cobalt-Aluminum (NCA) chemistry as the primary cathode material. Cathode Technology NCA chemistry ( Preferred by hobbyists requiring extreme runtime and high

The cell retains a significant portion of its capacity at lower temperatures, though discharge voltage is lower at -10°C compared to 25°C. Typical Applications

Suitable for remote‑controlled vehicles, drones, and other high‑performance models.

The balance of high capacity and solid high-current capability makes the NCR21700T highly versatile across multiple demanding industries:

Retains roughly 70% to 80% of its original capacity after 300 to 500 full charge/discharge cycles. Charging the cell to 4

First, a bit of trivia. This cell is famously known as the "Tesla cell." When Tesla moved from 18650s to 21700s for the Model 3, Panasonic was their primary partner. While Tesla uses a slightly modified chemistry (the "Tesla-specific" variant), the off-the-shelf is the closest you can get to automotive-grade power.

The Panasonic NCR21700T is suitable for a wide range of applications, including:

What is the required by your application?

Panasonic claims (retaining 70% capacity) under standard conditions.

The unique balance of high capacity (4800mAh) and moderate-to-high current draw makes the NCR21700T a versatile workhorse for several industries:
