Based on the official specifications for the Panasonic NCR21700T (typically referred to as the ), I have developed a comprehensive technical report. This report is designed to be useful for battery engineers, product designers, and procurement specialists.
The Panasonic NCR21700T is suitable for a wide range of applications, including: panasonic ncr21700t datasheet
The Panasonic is a high-capacity, high-discharge lithium-ion cell designed for demanding applications like electric vehicles, high-drain power tools, and high-performance flashlights. Core Specifications Overview Nominal Capacity 5000mAh (Minimum 4900mAh) Nominal Voltage Max Charge Voltage Max Continuous Discharge 30A (Continuous) / 40A (Peak) Energy Density ~263 Wh/kg Life Cycle Over 1000 cycles Dimensions 21.1mm (D) x 70.4mm (H) Deep Dive Analysis Discharge Characteristics: NCR21700T Based on the official specifications for the
The 5,000 mAh rating is industry-leading for 21700 cells available to the public. At 0.2C (1,000 mA) discharge to 2.5V at 25°C, a fresh cell will deliver at least 5,000 mAh. However, at higher drain (e.g., 10A), expect capacity to drop to ~4,600–4,700 mAh due to internal resistance losses. The datasheet’s “minimum capacity” of 4,900 mAh ensures consistency across production batches. Nominal Voltage: Typically rests around 3
Charge at 2500mA (0.5C) until the voltage reaches 4.2V.
