Device is not discharging cannot measure power usage


Battery longevity is directly related to the level and duration of the stress inflicted, which includes charge, discharge and temperature.

If your protection circuit cuts off at 3.2v, then the relatively high-quality Torchy cell had only discharged 85% of its nominal capacity.

The 3,200mAh Energy Cell is discharged at 0.2C, 0.5C, 1C and 2C. The circle at the 3.0V/cell line marks the end-of-discharge point at ...

The 1950mAh Power Cell is discharged at 0.2C, 0.5C, 1C and 2C and 10A. All reach the 3.0V/cell cut-off line at about 2000mAh.
