While many high-power cells have a flat discharge curve that drops sharply near the end, the NCR21700T offers a very smooth, gradual slope. This allows devices with simple voltage-based fuel gauges to estimate remaining capacity with reasonable accuracy.
| Parameter | Recommended | Absolute Max | |-----------|-------------|---------------| | Charge voltage | 4.20 V | 4.25 V (risk of plating) | | Standard charge current | 1.5 A (0.3C) | – | | Fast charge current | 3.0 A (0.6C) | 4.0 A (must cut off at 4.20V) | | Trickle charge (below 2.5V) | Do not apply – cell considered damaged | | | Temperature range | 0°C to +45°C | – | panasonic ncr21700t datasheet
The NCR21700T is an , not a Power Cell. While its capacity is massive, its recommended continuous discharge current is typically rated around 10A . While many high-power cells have a flat discharge
