Average voltage during discharge after standard charge. 2 Nominal voltage V 3.7 3 Voltage out of box V 3.75 4 Charge method Constant current/voltage 5 Maximum charging voltage V 4.2 6 Discharge termination voltage V 3.0 7 Maximum continuous charge mA 1C current 8 Maximum continuous discharge mA 1C current 9 Operating charge 0~45 Temperature discharge 10~50 4.2 Safety testing of batteries 1 Impact Put the battery on a impaction platform, let a 10Kg hammer No explosion, no fall from a height of 1m to the battery which is fixed on the smoke, no fire platform(The largest surface area of the battery, should be perpendicular to the table). 2 Short-circuit Short the battery positive and negative with the 0.1 No explosion, no resistor for 1h. smoke, no fire, no leakage 3 Overcharge Charge at 1C5A till the voltage of battery reach 4.8V. No explosion, no smoke, no fire, no leakage 4 Over-discharge Discharge at 1C5A till the voltage reaches 2.75V,then No explosion, no external load(30*N) discharge for 24hours smoke, no fire, no leakage 4.3 Battery performance test No. Item Content Requirement Standard charge is charge at 1C5A constant current till the Standard 1 voltage reach 4.2V,constant voltage charging till current less charge than 0.01C5A C1000mAh Rated Rated capacity is after standard charge ,then discharge at 2 capacity 0.2C5A constant current till cut-off voltage 2.75V After standard charge, then discharge at 0.5C5A till cut-off 3 Cycle life voltage 2.75V.Repeat the test until two consecutive discharge 300 times capacity is less than rated capacity 80%. 150m 4 Resistance The internal resistance when charge in 40-50% capacity After standard charge at 20 ,discharge constant current at 1C5A to termination voltage 2.75V then compare battery capacity with experimental results at different temperatures 25 .(After the temperature change more than three hours) 5 Temperature Charging temperature Discharge temperature -10 0 25 50 25 30% 85% 100% 102% Charge After standard charge,20 5 storage in 30 days later. Battery capacity is 6 retention greater than 90% of rated capacity with 0.2C5A discharge. 4.4 Battery environment performance testing
