NCR21700T Manufacturer: Panasonic Format: 21700 Cylindrical Chemistry: NCA (Nickel Cobalt Aluminum) / Li-ion
According to performance tests, high-drain usage (like 15A-20A constant) will cause the cell temperature to rise rapidly, often exceeding 60°C to 70°C without active cooling.
These specifications establish the NCR21700T as a "capacity cell" with good current handling, making it a versatile choice for many applications.
The is a powerhouse in the lithium-ion battery market, specifically designed for high-capacity applications requiring reliable energy delivery . As devices demand longer runtimes—from electric tools to electric vehicles (EVs) and advanced power banks—the 21700 form factor has become the new standard, surpassing the traditional 18650 in both capacity and energy density. panasonic ncr21700t datasheet hot
: 21700 (21mm x 70mm), which offers higher energy density than traditional 18650 cells. Промелектроніка
is an exceptional 5000mAh, 3.6V lithium-ion battery. It perfectly balances high capacity with the ability to handle high-drain applications. While it can operate under "hot" conditions, it is best utilized in systems that manage heat efficiently to ensure longevity and safety. If you are looking to purchase, you can find the Original PANASONIC NCR 21700T from BDtronics or review technical data sheets on Promel. If you'd like, I can: Compare the against the or .

While powerful, users should note that these are usually "flat-top" cells and may require specific adapters or spacers for use in standard consumer flashlights.

If you draw more than the rated continuous current (e.g., 20A+):
The "T" variant is noted for its ability to handle higher current draws compared to standard energy-focused cells.
The Panasonic NCR21700T (often cited as having a 5000mAh capacity) represents a shift towards high-energy-density cells that still maintain decent discharge capabilities. Key Data Sheet Highlights NCR21700T Size: 21700 (21mm Diameter x 70mm Length) Nominal Capacity: 5000mAh (Typical) / 4850mAh (Minimum) Nominal Voltage: 3.6V Maximum Charging Voltage: 4.2V
At first glance, 15A continuous and 5000 mAh is excellent. But here is the catch: The datasheet says maximum 15A, but it does not say "15A without significant temperature rise." In fact, the thermal appendix of the datasheet (which most people skip) warns that operating near 15A for extended periods will push the cell surface temperature past 65°C—the official cutoff for safety.
The term "hot" in battery datasheet terms generally refers to a cell operating at its upper temperature limits during high-current discharge. The Panasonic NCR21700T datasheet indicates a discharge range of -20°C to +60°C. However, operating near or exceeding +60°C is considered critical. What Happens When the NCR21700T Gets Hot?
