Panasonic Ncr21700t Datasheet Hot
According to Panasonic technical documentation , maintaining proper temperature is critical for safety and longevity: Charging: 10°C to +45°C. Discharging: -20°C to +60°C.
The following data highlights the primary performance metrics typical for the NCR21700 series : Approximately 4800mAh to 5000mAh . panasonic ncr21700t datasheet hot
Disclaimer: Always use proper battery safety gear. Never use a damaged lithium cell. Consult the official Panasonic datasheet for your specific batch number before designing a battery pack. Disclaimer: Always use proper battery safety gear
The datasheet specifies a maximum operating temperature of 60°C for the case . If you measure the metal can and it reads 65°C, you are outside of the warranty spec. At 70°C, the separator inside the cell begins to shrink. This is the physical mechanism that causes a short circuit. A hot NCR21700T is not just uncomfortable; it is structurally failing. The datasheet specifies a maximum operating temperature of
Thus, when searching for "datasheet hot," users are looking for the thermal derating curve —which Panasonic published only in internal revisions, but third-party tests confirm that for safety, you should not exceed if you want the cell to stay below 50°C.
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.
If the "hot" factor is a dealbreaker, the Panasonic datasheet itself suggests looking at different chemistries:
