1. Charging current:Cannot surpass the biggest charging current which in this specification stipulated.

2. Charging voltage:Does not have to surpass the highest amount which in this specification stipulated to decide the voltage.

3. Charge temperature: The battery must carry on the charge in the ambient temperature scope which this specification stipulated.

4. Uses the constant electric current and the constant voltage way charge, the prohibition reverse charges. If the battery positive electrode and the hode meet instead, can damage the battery. 

Discharging current 

The discharging current does not have to surpass this specification stipulation the biggest discharging current, the oversized electric current electric discharge can cause the battery capacity play to reduce and to cause the battery heat.

Dicharge temperature

The battery discharge must carry on in the ambient temperature scope which this specification stipulated. 



After the short time excessively discharges charges immediately cannot affect the use, but the long time excessively discharges can cause the battery performance, battery function losing.The battery longterm has not used,has the possibility to be able to be at because of its automatic flashover characteristic certain excessively discharges the condition,for prevented excessively discharges the occurrence, the battery should maintain the certain electric quantity.
