0°C to 45°C (Charging at sub-zero temperatures causes lithium plating, leading to permanent capacity loss and internal short circuits).
The mathematical and physical parameters of the Panasonic NCR21700T establish its baseline performance metrics under standard testing conditions ( 25∘C25 raised to the composed with power C 5000 mAh (Typical) / 4900 mAh (Minimum) Nominal Voltage: 3.6V Maximum Charge Voltage: 4.20V ±plus or minus Discharge Cut-off Voltage: 2.50V
Panasonic includes a lengthy safety section. Key points:
Under , internal resistance causes "voltage sag." While the cell can handle these loads, sustained high-current draw increases internal temperature and reduces overall efficient runtime. 4. Lifecycle and Degradation panasonic ncr21700t datasheet
Efficient for large-scale battery banks.
As a high-capacity lithium-ion cell, the Panasonic NCR21700T must be handled with care.
The shift from the traditional 18650 form factor to the 21700 form factor was driven by the need for higher energy density without a massive increase in physical footprint. The NCR21700T excels in several demanding industries: 0°C to 45°C (Charging at sub-zero temperatures causes
For procurement, these cells are typically available through authorized electronics distributors and specialized component suppliers. Ensuring the authenticity of the cells is vital for maintaining the safety and performance standards outlined in the datasheet.
