Ensure the operating environment remains between 15°C and 25°C whenever possible. 5. Applications and Use Cases
The Panasonic NCR21700T is a high-performance, industrial-grade lithium-ion cell. It stands out in the 21700 form factor market for balancing high capacity with reliable discharge rates.
Here’s a for a Panasonic NCR21700T datasheet based on typical specifications for this model (commonly used in high-drain applications). Please verify with an official Panasonic document before final use.
4,800 mAh (typical) / 4,700 mAh (minimum). Nominal Voltage: 3.6V. Charging Voltage: 4.2V ± 0.03V. Standard Charging Current: 1,410 mA (0.3C). panasonic ncr21700t datasheet
The voltage is held fixed at 4.2V while the current naturally tapers down. Charging terminates once the current drops below a designated threshold (usually 50mA to 100mA).
. Discharging below this point risks permanent chemical damage to the internal components. Durability and Longevity: This cell is rated for 1000+ cycles
