The cell includes an integrated PTC (Positive Temperature Coefficient) resistor that increases resistance during temperature spikes to prevent short-circuits, alongside a built-in safety valve to relieve internal pressure. Charging and Storage Guidelines panasonic ncr21700t datasheet
The voltage is held at 4.2V while the current tapers down. Charging stops when the current drops below the cut-off threshold (typically around 94 mA). Discharge Performance
The is the "muscle car" of 21700 cells. It has massive displacement (capacity) and solid horsepower (amps). It is not the absolute highest discharge cell on the market, but it offers one of the best capacity-to-amperage ratios available.
Lithium-ion chemistries require strict environmental boundaries to operate safely. The NCR21700T datasheet specifies strict temperature windows for different operational states: 0°C to +45°C Discharge Temperature: -20°C to +60°C Storage Temperature: -20°C to +50°C (less than 1 month) Safety Warnings Safety and longevity depend heavily on staying within
The cell must be charged within the temperature range of . Charging outside these limits can cause irreversible damage, including lithium plating on the anode, which reduces capacity and poses a safety risk.
Disables the pack if temperature sensors register above 60°C during operation.
The Panasonic NCR21700T is a high-capacity 21700-format lithium‑ion cylindrical cell marketed for high‑energy applications that require long run time and reasonable discharge capability. With a nominal voltage around 3.6–3.7 V and a published nominal capacity near 5,000 mAh, the cell represents a class of large-format cylindrical Ni‑rich/NC‑based (NCR-series) chemistries optimized for energy density rather than maximum continuous current. This treatise surveys its specification envelope, internal design and materials implications, electrical and thermal behavior, typical applications, performance tradeoffs, lifecycle and safety considerations, testing and modeling resources, supply/market context, and practical guidance for designers and end users.
