  Lithium battery 21700 life theory for charge cycle 1000 times.  Usually used in flashlights, lights, mobile medical equipment and so on.  Also can be combined, but with the difference between the plate and not with the board, the main plate with overdraft protection to prevent charging is obsolete, or the battery is too clean and lead to scrap batteries.  The charger for a mobile phone this month should be available, that is, the kind of portable charge at any time, should be able to meet the overall needs of customers charging.  And this mobile phone charger is universal!  Mobile interface too! ​ 【Lithium Battery Application and precautions】   1, do not use non-lithium battery charger   2, never overpay more   3, the standard voltage lithium battery 3.6-3.7 V, after charging voltage reached 4.2 V, put the voltage 2.75 V.   4, do not use the recommendations stored fully charged, and charged once six months.   5, this battery has no memory, you can always feel free to charge.   6, the minimum battery temperature is 20 degrees higher, the maximum temperature is 50 degrees.   7, long-term (more than 3 months) do not use a lithium battery, should be charged up to 50% of the power to save.   8, due to different batches of different plant periods using different raw materials, batteries can exist before buying batteries blue, purchase red, normal phenomenon, each of the batteries have been tested before leaving the factory, please do not hesitate to use.   1 cell Parameters / Cell code Parameters s   No. Details / Details Technical characteristics / technical data Note   1 Rated power   4000 mAh 0.2C Standard discharge   2 Minimum Capacity 3950 mAh 3 Rated voltage Q 3.7 V Means Control Voltage Operating voltage 4 Voltage Delivery 3.85 ~ 3.90V Within 10 days from the factory At the factory for 10 days 5 Charging Voltage 4.2 V ± 0.03 V On the standard charging method 6th Standard charging method 0.5C direct current, 4.2 VDC charge voltage up to 4.2 V, continue charging until the current decline to ≤ 0.01C   7th Charge current Charging current 0.5C 2000mA Standard, charging time about 3 h (art) Standard charging, the time is about 3 hours (for reference) 1.0C 4000mA Fast charging, charging time about: 2 h (art) Quick charge, the time is about 2 h (for reference) 8 Standard discharge method Standard discharge mode 0.2C constant discharge current 3 V
