26650 3600mah lithium iron battery cell for high-drain devices/flashlights
About 26650 lithium phosphate battery cell.
Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable.
Deligreen's 18650 supplies good quality and real 1500mah capacity.
All 26650 we supply is grade A.

Quality Testing
Deligreen's 26650 has lab passed with spec,pls contact us for the esting report.
| Items | Test Conditions | Specification |
|
Standard Charge |
(The "Standard Charge" means charging with constant current 0.2C 5 to3.65V, then charging with constant voltage 3.65V to 0.01C 5 under 20±5 , ℃ 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 0.2C 5 to cut-off voltage at 2.0V at 20±5℃ rest for 30minutes after the Standard Charge. |
Nominal Capacity ≥3600mAh |
|
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 |
Test the cell initial capacity using 0.2C 5 current at 23±2℃ and record,then charge the cells with 45% capacity, then storage for 3, 6, 12 months respectively at 20±5℃and relative humidity of 45%~75%, then the cell is cycled for 5 times with charge with 0.2C 5and discharge with 0.2C 5 at 23±2℃, The maximum discharge capacity (longest discharge time) is recorded. |
0.2Cdischarge time: After 3 months storage ≥4.5hrs; After 6 months storage ≥4.25hrs; After 12 months storage ≥4.0hrs) |
| The cell is charged and discharged using 0.2C 5 at 20±5℃. The discharge | Capacity Retention | |
| capacity is C1. The cell is stored for 28 days in 20 ±5℃ after fully charged and | C2/C1≥90% | |
| then is discharged using 0.2C 5 at 20±5℃. The capacity is defined as C2. | ||
|
After the test as C 2 , The cell is charged and discharged using 0.2C 5 at 20± 5℃, The discharge capacity is C3. |
Capacity recoverable ratio C3/C1≥95% |
|

Temperature Performance |
Cells shall be charged according to 5.1 and discharged at 0.2C 5 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℃≥95% | ||
|
Constant Temperature and Humidity |
Under the temperature of 23±2℃, after charging the cell with 0.2C 5 ,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 cellswith0.2C 5 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. |
