Product Features
Unit Details
- Cycle Life
- Temperature: 77-86 F(25-30 C); Charge, 1C CC to 14.6V, and CV to 200mA cut off; Discharge, 1C DC discharge to 9.2V, 80% or more of 1st cycle capacity at 1C discharge of operation, cycles quantity must not less than 2,000 cycles.
- Remarks: Rest 10 min. after charge and discharge
- Standard Charge: Charging the cell initially with constant current at 1C and then with constant voltage at 14.6V (accuracy +(or minus) 0.05V) until charging current declines to 0.02C at 77-86 F(25-30C)
- Standard Discharge: Discharging the cell with constant current at 1C till cut-off voltage at 9.2V. Temperature: 77-86 F (25-30C)
- Initial Internal Impedance: This means AC impedance of the pack measured at 1 KHz after half fully charged. Initial Internal Impedance < (or equal)20m(ohm)
- Initial Capacity: The capacity means the discharge capacity of the battery, which is measured with discharge current of 1C with 9.2V cut-off voltage after the standard charge.
- Initial Capacity: @95% normal capacity. Temperature: 7 -86 F(25-30 C).
