The chemistry is stable, but high temperatures increase internal impedance, causing higher voltage sag, as shown in detailed thermal characterization reports (e.g., Batemo Cell Model ). Winner for Best All-Arounder : Panasonic NCR21700T
The allowable charging range is narrower (0°C to +45°C). Never charge a hot battery.
According to Panasonic technical documentation , maintaining proper temperature is critical for safety and longevity: Charging: 10°C to +45°C. Discharging: -20°C to +60°C.
