PRODUCT SPECIFICATION Description Document No. Date Rev
Lithium Ion LG 18650 HG2 3000mAh PS-HG2-Rev5 2017-03-31 5 4.1.2 Standard Discharge “Standard Discharge” shal consist of discharging at a constant current of 600mA to 2.0V. Discharging is to be performed at 23 ºC ± 2 ºC unless otherwise noted (such as capacity versus temperature). 4.1.3 Fast Charge / Discharge condition Cells shall be charged at constant current of 4000mA to 4.2V with end current of 100mA. Cells shall be discharged at constant current of 10000mA and 20000mA to 2.0V. Cells are to rest 10 minutes after charge and 30 minutes after discharge. 4.2 Electrical Specification Item Condition Specification 4.2.1 Cell shall be measured at 1kHz after charge per ≤ 20 mΩ, without PTC Initial AC Impedance 4.1.1. 4.2.2 Cell shall be charged per 4.1.1 and discharged 3000 mAh (Cnom) Initial Capacity per 4.1.2 within 1h after full charge. 4.2.3 Cells shall be charged and discharged per ≥ 60 % (of Cnom in 2.1) Cycle Life 4.1.3, 300 cycles(10A) and 200 cycles(20A) .A cycle is defined as one charge and one discharge. 301st (10A) and 201st (20A) discharge capacity shall be measured per 4.1.1 and 4.1.2 4.3 Environmental specification. Item Condition Specification 4.3.1 Cells shall be charged per 4.1.1 and stored in a Capacity remaining rate Storage Characteristics temperature-controlled environment at 23ºC ± ≥ 90% (of Cnom in 2.1) 2ºC for 30 days. After storage, cells shall be discharged per 4.1.2 to obtain the remaining capacity. 4.3.2 Cells shall be charged per 4.1.1 and stored in a No leakage, High Temperature temperature-controlled environment at 60ºC for Capacity recovery rate ≥ Storage Test 1 week. After storage, cells shall be discharged 80% (of Cnom in 2.1) per 4.1.2 and cycled per 4.1.1 and 4.1.2 for 3 cycles to obtain recovered capacity. * Remaining Capacity : After storage, cells shall be discharged with standard condition(4.1.2) to measure the remaining capacity. ** Recovery Capacity : After storage, cells shall be discharged with standard discharge condition(4.1.2), and then cells shall be charged with standard charge condition(4.1.1), and then discharged with standard discharge condition(4.1.2). This charge / discharge cycle shall be repeated three times to measure the recovery capacity. 7/12
