lfp battery 6000mAh Electrical Characteristics

Items	Test Conditions	Specification
4.1(Stand & Charge)	(The "Standard Charge" means charging with constant current 0.5C5 to3.65V, then charging with constant voltage 3.65V to 0.01C 5 under 25±2 , ℃ charging time will not more than 3h.) (Use Lithium-ion battery charger, which with an accuracy ±0.05V.)
4.2Nominal Capacity	(The capacity means the discharge capacity of the cell, which is measured with discharge current 0.5C to cut-off voltage at 2.0V at 25 ± 2℃ rest for 30 minutes after the Standard Charge.)	(Nominal Capacity ≥6000mAh)
4.3 Cycle Life	At 25±2℃, 1C charge to 3.45V and discharge to 2.5V with 1 C discharge current, after 2000 cycles the discharge capacity is measured with 1C discharge current and 2.5V cut-off voltage.	≥80%Nominal Capacity
4.4(Storage Characteristic)	(Test the cell initial capacity using 0.5C 5 current at 25±2℃ and record,then charg the cells with 45% capacity, then storage for 3, 6, 12 months respectively a 25±2℃and relative humidity of 0%~75%, then the cell is cycled for 5 times with charge with 0.5C and discharge wit 0.5C at 25±2℃, The maximum discharge capacity (longest discharge capacity ) is recorded.	0.5Cdischarge time: After 3 months storage ≥5.7Ah; After 6 months storage ≥5.46Ah; After 12 months storage ≥5.16Ah)
(The cell is charged and discharged using 0.5C at 25±2℃. The discharge capacity is C1. The cell is stored for 28 days in 20 ±5℃ after fully charged and then is discharged using 0.5C at 25±2℃. The capacity is defined as C2.)	(Capacity Retention C2/C1≥85%)
(After the test as C 2 , The cell is charged and dischargedusing 0.5C	(Capacity recoverable ratio C3/C1≥95%)
4.5(Rate Capacity)	1. Under the temperature of 25±2℃,the discharge capacity is measured with 0.5 C discharge current and 2.0V cut-off voltage after full charged.	≥100%Nominal Capacity
2. Under the temperature of 25±2℃，the discharge capacity is measured with 1 C discharge current and 2.0V cut-off voltage after full charged.	≥98%Nominal Capacity
3. Under the temperature of 25±2℃，the discharge capacity is measured with 3 C discharge current and 2.0V cut-off voltage after full charged.	≥96%Nominal Capacity
