| Item | Test methods and condition | Criteria |
|
2.1 | Nominal Capacity | The capacity means the charge capacity of the cell, which is measured with discharge current of 1.2Awith 3.0V cut-off voltage after standard charge.
|
≥390mAh |
| 3A Capacity
| The capacity means the charge capacity of the cell, which is measured with discharge current of 3A with 3.0V cut-off voltage after standard charge.
|
≥380mAh | |
|
2.2 |
Cycle Life
|
Test condition: Charge:0.5C to 4.2V Discharge: 1.0C to 3.0V 80% or more of 1st cycle capacity at 0.2C discharge of operation.
|
≥300 times |
|
2.3 | Self-discharge |
After the standard charging, storied the cells under the condition as No.9.5 for28 days, then measured the capacity with 0.2C till 3.0V.
| Residual capacity >90%
|
3.Period of Warranty
The period of warranty is 12 months from the date of shipment. Hange guarantees to give a replacement in case of cells
with defects proven due to manufacturing process instead of the customer’s abuse and misuse.
Storage and Others
Long Time Storage
The detection voltage is more than 3.92V within 3 days, within a month to maintain the voltage above 3.90V, three internal voltage to maintain more than 3.80V.
The retention rate within one month of receipt of goods is 97 % of the nominal capacity, the retention rate within three months is 95 % of the nominal capacity, the retention rate within six months is 92 % of the nominal capacity, and the retention rate within twelve months is 85 % of the nominal capacity.
4. Other The Chemical Reaction
Because batteries utilize a chemical reaction, battery performance will deteriorate over time even if stored for a long period of time without being used. In addition, if the various usage conditions such as charge, discharge, ambient temperature, etc. are not maintained within the specified ranges the life expectancy of the battery may be shortened or the device in which the battery is used may be damaged by electrolyte leakage. If the batteries cannot maintain a charge for long periods of time, even when they are charged correctly, this may indicate it is time to change the battery.
