Panasonic Ncr21700t Datasheet Hot |verified|

: During high-rate discharge (e.g., 20A+), internal resistance can cause significant surface temperature increases. For safety, these cells should be monitored to ensure they do not exceed a surface temperature of 60°C during operation.

Due to its high energy density and current output, this cell is a "hot" choice for: Panasonic NCR2170-M Battery Data, Model and Report Similar

This article is for informational purposes based on publicly available datasheets and third-party tests. Always verify with Panasonic’s official released documentation. Do not exceed 60°C surface temperature during discharge. Battery cells can explode if misused.

The datasheet includes a temperature vs. discharge curve. At room temperature (25°C), you get 4,000 mAh. At 0°C, you lose about 20% capacity. But at 60°C+ (where you operate at 35A), cycle life drops by nearly 50%. Running this cell at its "hot" max rating means you are sacrificing lifespan for performance.

On the surface, the NCR21700T is a direct competitor to the Samsung 40T and the Molicel P42A. However, unlike its rivals, the Panasonic cell uses a modified NCA (Nickel-Cobalt-Aluminum) chemistry that trades ultra-low resistance for higher energy density.
