Initial Performance Test:
| Item | Test Method and Condition | Requirements |
- Open-Circuit
Voltage | The open-circuit voltage shall be measured within 24 hours after standard charge. | ≥4.08V |
- Internal impedance
| Internal resistance measured at AC 1KHz after 50% charge. | ≤300mΩ |
- Minimal Rated
Capacity | The capacity on 0.2C5A discharge till the voltage tapered to 3.0V shall be measured after rested for 30min then finish standard charge. | Discharge Capacity ≥95mAh |
Cycle Life and Leakage-Proof:
| No. | Item | Criteria | Test Conditions |
| 1 | Cycle Life (0.2 C5A) | Higher than 70% of the Initial Capacities of the Cells | Carry out 500cycle Charging/Discharging in the below condition. ◆Charge:Standard Charge, per 3.3.1 ◆Discharge:0.2 C5A to 3.0 V ◆Rest Time between charge/discharge:30min. ◆Temperature:20±5℃ |
| 2 | Leakage-Proof | No leakage (visual inspection) | After full charge with standard charge, store at 60±3℃, 60±10%RH for 1 month. |

Standard Test Conditions:
Test should be conducted with new batteries within one week after shipment from our factory
and the cells shall not be cycled more than five times before the test.
Unless otherwise specified, test and measurement shall be done under temperature of 20±5℃
and relative humidity of 45~85%.
If it is judged that the test results are not affected by such conditions, the tests may be
conducted at temperature 15~30℃ and humidity 25~85%RH.
