Diameter is defined as the largest data value measured on the "A" area of a cylindrical cell
Height :
≤ 65.15 mm
Performance Specification
Standard Charge
Unless otherwise specified, “Standard Charge” shall consist of charging at constant current of 0.5C. The
cell shall then be charged at constant voltage of 4.20V while tapering the charge current. Charging shall
be terminated when the charging current has tapered to 50mA. For test purposes, charging shall be
performed at 23ºC ± 2ºC.
Standard Discharge
“Standard Discharge” shall consist of discharging at a constant current of 0.2C to 2.50V. Discharging is to
be performed at 23 ºC ± 2 ºC unless otherwise noted (such as capacity versus temperature).
High Drain rate Charge/discharge condition
Cells shall be charged at constant current of 0.5C to 4.20V with end current of 50mA. Cells shall be
discharged at constant current of 0.5C to 2.50V. Cells are to rest 10 minutes after charge and 20 minutes
after discharge.
