1,Description

     1,1Model:GMB371042-3.7V-110mAh moon LiPo battery

2,Specification

     2,1Assembled cell parameters

2.1.1Charge Voltage      4.2V

2.1.2Overcharge protection voltage     4.28 minus and plus 0.08V 

2.1.3Nominal Voltage    3.7V   The average value of voltage during the discharging period (with standard charge and discharge).When shipping ,the voltage without load is between 3.6V and 3.85 V.

2.14Nominal Capacity  Typ:110mAh @0.2C   Discharge Min:100mAh   Nominal capacity refer to the capacity of 0.2C discharge to 2.8V cut-off voltage ,after charging with standard method.

2.15Charge Current  

less than zero celsius degree    Charge Current :charge shall be prohibited

zero celsius degree to ten celsius degrees     Charge Current: 0.1C Max

ten celsius degrees  to fifteen  celsius degrees     Charge Current :0.2C Max

fifteen celsius degrees to twenty five  celsius degrees  Charge Current :0.5C Max

twenty five celsius degrees to forty five celsius degrees  Charge Current:0.5C Max

2.16Standard Charging method  CC/CV   0.2CC(constant current) charge to ,then CV(constant voltage 4.2V) charge till charge current decline to less than 0.05C .

2.17Cycle life     more than 500 times    

One cycle refer to one charge period and then one discharge period.

Test condition:

Charge:0.2C to 4.2V

Discharge:0.2C to 2.8V

The cycle life is the cycle times when the discharge capacity is about 60% of the rated capacity.

2.18   Initial Impedance      less than 280 millohm     Internal resistance measured at AC 1KHz after 50% charge.

2.19   Max.Discharge Current    0.5C   

2.10   Discharge Cut-off Voltage    3.0V

2.11   Operating Temperature    

Discharge:-10 celsius degrees to +60 celsius degrees

2.12   Long term storage temperature     +5 celsius degrees to +35 celsius degrees  

Relative humidity:45-75%  RH

Voltage :3.8 minus and plus 0.1 V

Cell must be stored at 3.6V-3.85V .Over long storage periods cell should be cycled every 90 days .The method is to do a charge -discharge cycle with standard method ,then charge to 3.6V-3.85V

2.13  Cell Weight   Approx:2g

2.14  PCM   YES

2.15  Assemblage Dimension

Length:42.60mm Max

Width:10.3&8.7 mm Max

Thickness:3.7 mm Max
