voltage/constant current (4.2 V, 1500mA (max), 2
hours, 20°C), the average of the capacity (ending
voltage of 3 V at 20°C) that is discharged at a standard
current (430mA).

To ensure safety, the referenced Li-ion cell is not sold as a
bare cell. Li-ion cells must be integrated with the
appropriate safety circuitry via an authorized Panasonic
Li-ion pack assembler.
