 Storage
●The Li-ion polymer LI-ion battery pack should be stored in a cool, dry and well-ventilated area, and should be far from the fire and the high temperature. 
●The polymer LI-ion battery should store in the product specification book stipulation temperature range, the best storage temp. is 25±5℃. The best humidity is 60±15%.
●The polymer LI-ion battery should be stored within room temperature, and charged to 40%~60% electric quantity(3.85V). In order to avoid over-discharge, we suggest charge and discharge the batteries every three months.,Then charge to40%~60%electric quantity(3.85V).

 Transportation
●Do not mix the polymer LI-ion battery products with other cargoes.
●Do not immerse the li-ion polymer LI-ion battery products in water or allow it to get wet.
●Do not over 7 layers staking and upside-down.
●The highest temperature in transportation is lower than 60℃.

Use Attentions
To ensure proper use of the polymer LI-ion battery please read the manual carefully before using it.

 Warnings
●Do not expose to, dispose of the polymer LI-ion battery in fire.
●Do not put the polymer LI-ion battery in a charger or equipment with wrong terminals connected.
●Avoid shorting the polymer LI-ion battery.
●Avoid excessive physical shock or vibration.
●Do not disassemble or deform the polymer LI-ion battery.
●Do not immerse in water.
●Do not use the polymer LI-ion battery mixed with other different type or model batteries.

 Charge
●polymer LI-ion battery must be charged in appropriate charger only.
●Do not leave polymer LI-ion battery in charger over 24 hours.
●Charging current: Can not surpass the biggest charging current which in this specification book stipulated.
●Charging voltage: Does not have to surpass the highest amount which in this specification book stipulated to decide the voltage.
●Charge temperature: The polymer LI-ion battery must carry on the charge in the ambient temperature scope which this specification book stipulated.
●Uses constant current and constant voltage way charge. PLS connect the positive and negative terminals in right way, or the polymer LI-ion battery may be damaged.
 

Discharge
●he discharging current should not surpass the biggest discharging current this specification book stipulation, The large discharge current can cause heat and lower capacity.            
●Discharge temperature: The polymer LI-ion battery discharge must carry on in the ambient temperature scope which this specification book stipulated.
●Over-discharge: After short time over discharge, then charge immediately won’t damage the polymer LI-ion battery. But the polymer LI-ion battery will be damaged for being long time over discharged. During long-term storage, the polymer LI-ion battery may be within over-discharging condition for self discharge. To prevent the occurrence of over discharging, the polymer LI-ion battery should maintain the certain capacity when storage.
 

Handling of Cell
●Soft Aluminium foil
Don’t strike polymer LI-ion battery with any sharp edge parts
Trim your nail or wear glove before taking polymer LI-ion battery
Clean worktable to make sure no any sharp particle
●Sealed edge may be damaged by heat above 100°C, bend or fold sealed edge.
●Avoid some components to contact the edge of packing foil of batteries
