Quality Testing
Deligreen's 26650 has passed laboratory testing according to specifications. Please contact us for the testing report.
Items Test Conditions Specification
Standard Charge The "Standard Charge" means charging with constant current 0.2C5 to 3.65V, then charging with constant voltage 3.65V to 0.01C5 under 28±3℃, charging time will not more than 8h. (Use Lithium-ion battery charger, which with an accuracy ±0.05V.)
Nominal Capacity The capacity means the discharge capacity of the cell, which is measured with discharge current 0.2C5 to cut-off voltage at 2.0V at 28±3℃ rest for 30 minutes after the Standard Charge. Nominal Capacity ≥3400mAh
Cycle Life After 2000 cycles of charge and discharge, the discharge capacity is measured with 0.2 C5A discharge current and 2.0V cut-off voltage. ≥80% Nominal Capacity
Storage Characteristic Test the cell initial capacity using 0.2C5 current at 23±2℃ and record, then charge the cells with 45% capacity, then storage for 3, 6, 12 months respectively at 28±3℃ and relative humidity of 45%~75%, then the cell is cycled for 5 times with charge with 0.2C5 and discharge with 0.2C5 at 28±3℃, The maximum discharge capacity (longest discharge time) is recorded. 0.2C discharge time: After 3 months storage ≥4.5hrs; After 6 months storage ≥4.25hrs; After 12 months storage ≥4.0hrs
Capacity Retention The cell is charged and discharged using 0.2C5 at 28±3℃. The discharge capacity is C1. The cell is stored for 28 days in 28±3℃ after fully charged and then is discharged using 0.2C5 at 28±3℃. The capacity is defined as C2. C2/C1≥85%
Capacity Recoverable Ratio After the test as C2, The cell is charged and discharged using 0.2C5 at 28±3℃, The discharge capacity is C3. C3/C1≥90%
Rate Capacity The discharge capacity is measured with 0.2 C5A discharge current and 2.0V cut-off voltage after full charged.
The discharge capacity is measured with 0.5 C5A discharge current and 2.0V cut-off voltage after full charged.
The discharge capacity is measured with 1 C5A discharge current and 2.0V cut-off voltage after full charged.
The discharge capacity is measured with 3 C5A discharge current and 2.0V cut-off voltage after full charged. 		≥100% Nominal Capacity

Items Test Conditions Specification
Temperature Performance Cells shall be charged according to 5.1 and discharged at 0.2C5 to 2.0 V. Cells shall be stored for 4 hours at the test temperature prior to discharging and then shall be discharged at the test temperature, The percentage shall be calculated using discharging capacity compared to the minimum capacity. No leakage, No Appearance defect
-20℃/25℃≥40%
-10℃/25℃≥60%
0℃/25℃≥85%
25℃/25℃≥100%
60℃/25℃≥96%
Constant Temperature and Humidity Under the temperature of 28±3℃, after charging the cell with 0.2C5, then put the cell into the constant temperature and humidity oven with 40±2℃ and 90～95% for 48h, then store the cells at RT for 2hrs, and discharge the cells with 0.2C5 to 2.0 volts. The cell should be no deformation, no rust, no leakage, no fire, no smoking and no explosion. Discharge time ≥3h
Free Fall Test The fully charged cell is dropped three times from a height of 1000 mm (the lowest point of the cell) onto a concrete floor. The cells or batteries are dropped so as to obtain impacts in random orientations. After the test, the cell shall be put on rest for a minimum of one hour and then a visual inspection shall be performed. No explosion, No fire, No smoke. The OCV after the test no less than 90% before free-fall test.
26650 battery performs very well in high temperature. If you want to use a battery in a high temperature environment, LFP battery is a good option.
