2. Basic Electrical Characteristics
| Items | Criteria | Test Method |
| Initial Shipment Voltage | 3.75V～3.90V | Measure with voltmeter. |
| Minimal Capacity(CR) | ≥600mAh | Standard Discharge after Standard Charge and rest 10min. |
| 1C5A Discharge Capacity | ≥90%×CR | 1C5A discharge to the Discharge Cut-off Voltage after Standard Charge and rest 10min. |
| Temperature Characteristics | Discharge Capacity : 55℃: ≥85％×CR 0℃: ≥80％×CR -10℃:≥60％×CR | After Standard Charge, the battery is stored at (-10 ± 2)℃ for 4hours, and then at the same temperature 0.2C5A discharges to the Discharge Cut-off Voltage. According to this procedure, test (0 ± 2)℃, (55 ± 2)℃ discharge capacity, respectively. |
| Cycle Life | Discharge Capacity(501th cycle )≥80%×CR | A cycle is defined as a Standard Charge, 10 minute-rest and Standard Discharge.The battery is to be cycled for 501 times. |
| Remark: 1."Standard Charging" means 0.2C5A (38mA) CC(constant current) charge to Charge Limited Voltage, then CV(constant voltage) charge till charge current decline to 0.02 C5A at 23±2℃. 2."Standard Discharging" means 0.2C5A (38mA) discharge to the Discharge Cut-off Voltage at 23±2℃. | ||
3. Safety Characteristics
| Items | Criteria | Test Method |
| Over-charge | No fire. No explosion. | Charging to 6V with Maximum Charging Current after Standard Discharge, then CV Charge till current decline to End-of-Charge Current or CV time is more than 7hours. |
| Short-Circuit | The maximum Temperature: ≤150℃. No fire. No explosion. | Rest for 30miniutes at (55±2)℃ after Standard Charge, then short-circuit battery by connecting the positive and negative terminals with a circuit load having a resistance load(copper wire) of 80±20mΩ.Test can be terminated when battery surface temperature has returned to ±10°C of environment temperature. |
| Thermal Abuse | No fire. No explosion. |
The battery is to be heated in a gravity convection or circulating air oven after Standard Charge. The temperature of the oven is to be raised at a rate of 5±2℃per minute to a temperature of 130 ±2°C and remain for 10 minutes. |
4. Reliability Characteristics
| Items | Criteria | Test Method |
| Static Humidity and Temperature | Retention Capacity:≥80%×CR Recoverable Capacity ≥85% ×CR No deformation. No rupture. No smoke. No leakage | After Standard Charge, the battery is stored at 40±2℃ and 90% -95%RH for 48hours, then rest for 2hours at 23±2 ℃ . Standard Discharge to test its retention capacity, and then perform a cycle with Standard Charge and Standard Discharge procedure to test recoverable capacity |
| Vibration | OCV≥3.6V No leakage. No fire. No explosion | After Standard Charge, the battery is fixed to vibration table and subjected to vibration cycling that the frequency is to be varied at the rate of 1Hz per minute between 10Hz and 55Hz, the excursion of the vibration is 1.6mm. The battery shall be vibrated for 30 minutes per axis of XYZ axes. |
| Drop | OCV≥3.6V No leakage. No fire. No explosion. | After Standard Charge, the battery is to be dropped from a height of 1 meter onto concrete board for 6 times, then measure Open Circuit Voltage. |
