Data parsed from official testing documentation yields a distinct profile for the bare cell: NCR21700 data sheet Safety Protocols and Environmental Limits
The voltage is held at 4.2V while the current naturally tapers down. Charging terminates once the current drops below a designated threshold (usually around 50mA to 100mA). Discharge Performance Curves
Frequently draining the cell completely down to 2.5V stresses the chemical structure. 5. Safety Protocols and Environmental Limits
