Lishen LS LR2170SA cell specification

1 SCOPE
The product specification describes the requirements of the Cylindrical Lithium-ion Cell to be supplied to the
customer by Tianjin Lishen Battery J/S Co.,Ltd.
2 DESCRIPTION AND MODEL
2.1 Description : Cylindrical Lithium Ion Cell
2.2 Model : LR2170SA
3 GENERAL SPECIFICATIONS
3.1 Nominal Capacity 4000mAh (at 0.2C Discharge)
Minimum Capacity 3900mAh (at 0.2C Discharge)
Nominal capacity is measured by the discharge at 0.2C to 2.75V end voltage after standard fully charged
according to specification at 25℃.
3.2 Maximum Charge Voltage 4.20V
3.3 Average working Voltage 3.65V@0.2C
3.4 Standard Charge Method Constant Current and Constant Voltage (CC/CV)
Current 0.5C (2000mA)
Voltage 4.2V
End Current 80mA±5mA
3.5 Maximum Charge Current 0℃ ≤ T ≤ 5℃ 0.1C (400mA)
5℃ < T ≤ 15℃ 0.2C (800mA)
15℃ < T ≤ 45℃ 0.5C (2000mA)
3.6 Standard Discharge Constant Current (CC)
Current 0.5C (2000mA)
End Voltage 2.75V
3.7 Maximum Discharge Current -20-5℃ 1.0C (2000mA)
5-45℃ 3.0C (12000mA)
45-60℃ 1.5C (6000mA)
3.8 Cycle Life 1000th cycle ≥80% of 1st Capacity (0.5C/1.0C at 25℃)
If discharged at high rate and high temperature frequently, cell cycle life will be shorten.
3.9 Weight of Bare Cell 68±2g
3.10 Operating Enviromental Temperature Charge 0°C ~ 45 °C
Discharge -20°C ~ 60°C
Diameter: 18.3 ± 0.2mm

Safety certification: MSDS un38 3 RoHS CB IEC62133 UL1642
