To help tailor this breakdown to your project, could you tell me a bit more about how you plan to use this cell? If you want, tell me: What is your ? What is the peak current draw of your application?
Datasheets provide the foundational boundaries for operating a battery cell safely. Physical Dimensions 21.1 mm (maximum) Height: 70.4 mm (maximum) Weight: Approximately 68.0 grams Form Factor: Cylindrical 21700 Electrical Characteristics Nominal Capacity: 4800 mAh (typical) Minimum Capacity: 4650 mAh Nominal Voltage: 3.6V – 3.7V Charging Voltage: 4.20V ± 0.05V Discharge Cut-off Voltage: 2.5V Current and Temperature Limits Standard Charge Current: 1.5A to 2.4A
Discharging below 2.5V can cause copper shunts to form inside the cell, creating an internal short when recharged. Overcharging past 4.25V can destabilise the chemical structure, leading to thermal runaway. Summary: Is the Panasonic NCR21700T Right for Your Project? panasonic ncr21700t datasheet
The shift toward high-capacity, high-drain lithium-ion cells has made the 21700 form factor an industry standard.
