New technology high capacity good quality3.7V 2600mAh li-ion 18650 battery

Specification 

1 Charging 

1.1 Charging current 

   Charging current should be less than maximum charge current specified in the Product Specification.Charging with higher current than recommended value may cause damage to cell electrical, mechanical,and safety performance and could lead to heat generation or leakage.

 1.2 Charging voltage 

   Charging shall be done by voltage less than that specified in the Product Specification(4.2V/battery).Charging beyond 4.30V,which is the absolute maximum voltage ,must be strictly prohibited. The charge shall be designed t o comply with this condition.

  It is very dangerous that charging with higher voltage than maximum voltage may cause damage to the cell electrical ,mechanical safety performance and could lead to heat generation or leakage.

1.3 Charging temperature 

  The cell shall be charged within 0℃~45℃range in the Product Specification

1.4 Prohibition of reverse charging 

  Reverse charging is prohibited .The cell shall be connected correctly .The polarity has to be confirmed before wiring.In case of the cell is connected improperly, the cell cannot be charged.Simultaneously,the reverse charging may cause damaging to the cell which may lead to degradation of cell performance and damage the cell safety,and could cause heat generation or leakage.

2 Discharging 

 2.1 Discharging current 

 The cell shall be discharged at less than the maximum discharge current specified in the Product Specification .High discharging current may reduce the discharging capacity significantly or cause over-heat.

 2.2 Discharging temperature 

  The cell shall be discharged within -20℃~30℃range specified in the Product Specification.

  2.3 Over-discharging 

 It should be noted that the cell would be at an over-discharged state by its self-discharge characteristics in case the cell is not used for long time.In order to prevent over-discharging,the cell shall be charged periodically to maintain between 3.7V and 3.9V

Over-discharging may causes loss of cell performance, characteristics,or battery functions

 The charger shall be equipped with a device to prevent further discharging exceeding a cut-off voyage specified in the Product Specification . Also the charge shall be equipped with a device to control the recharging procedures as follows:The cell battery pack shall start with a low current(0.01C)for 15-30minutes,i.e.pre-charging, before rapid charging starts .The rapid charging shall be started after the (individual)cell voltage has been reached above3.0V within 15-30munutes that can be determined with the use of an appropriate timer for pre-charging.In case the (individual) cell voltage does not rise to 3.0V within the pre-charging time ,then the charger shall have functions to stop further charging and display the cell/pack is at abnormal state.

3 Protection Circuit Module 

 The cell/battery pack shall be with a PCM that can protect cell /battery pack properly. PCM shall have functions of (1) overcharging prevention,(2)over-discharging prevention,(3)over current prevention to maintain safety and Prevent significant deterioration of cell performance. The over current can occur by external short circuit.

3.1 overcharging protection :

  Overcharging protection function shall stop charging if any one of the cells of the battery pack reaches 4.30±0.05V;

 3.2 over-discharging protection:

  Over-discharging prevention function shall work to avoid further drop in cell voltage of 2.75±0.10V

  Or less per cell in any cell of the battery pack. It is recommended that the dissipation current of PCM

  Shall be minimized to 0.5uA or less with the over-discharging prevention,the protection function shall monitor each back of the battery pack and control the current all the time.

4 Storage

 The battery shall be storied within-10℃~45℃range environmental condition.

 If the battery has to be storied for a long time (over 3 months),the environmental condition should be:Temperature:23±5℃,Humidity:35±20%RH

The voltage for a long time storage shall be 3.7V~3.9V range.

5 Handling Instructions 

  Read and observe the following and precautions to ensure correct and safe use of Li-polymer batteries.
