Specification for Lithium-Ion Rechargeable Cell
XCell N18650CP-35E
1 Preface
This specification describes the type, dimension, performance, technical characteristics, warnings and cautions of the lithium ion recharge-
able cell. The specification only applies to N 18650CP cell supplied by energy inside.
2 Definition
2.1 Standard charge method
At 25 ± 2°C, the cell is charged to 4.2 V at constant current of 0.5 C (1625 mA), then charged at constant voltage of 4.2 V until the current
tapers to ≤ 0.01C (32 mA) followed by resting for 5 min.
2.2 Standard discharge method
Under 25 ± 2°C, the cell is discharged to 2.5 V at a constant current of 0.2 C (650 mA).
2.3 Nominal capacity
Nominal capacity, signed as capacity and using mAh as unit, is obtained by discharging a cell via standard discharge method after it is stan-
dard charged.
