• Storage Temperature: -20°c~60°c

The is the button top version of the cell.










Good tracking between the cells and also constant capacity at any load, this looks good.














Flat top version



Official specifications:

• Nominal Voltage: 3.7v
• Max.Charge Voltage: 4.2±1v
• Discharge Cut-off Voltage: 3.0v
• Capacity: 700mah
• Stand Charge Current: 1.2A
• Max.Charge Current: 2.2A
• Standard Discharge Current: 1.2A
• Max Continue Discharge Current: 2.4A
• Size: Height:50±2.0mm Diameter: 14±2.0mm
• Cycle life: > 300 cycles
• Material: li-ion
• Operating Temperatue: 0~45°c
• Storage Temperature: -20°c~60°c

The is the flat top version of the cell.



This version also has good tracking between the cells and also constant capacity at any load, this looks good.
I expect they are using the same cell, i.e. they must have the same performance.






















Conclusion

The batteries has a good capacity for IMR batteries, even though it is lower than rated. The performance is also good, even at much higher current than they are rated for.
There is a very small difference between flat top and button top, the button top increases the resistance slightly.
I will rate this battery acceptable.
