3. Lithium ion Battery operation instruction

3.1 Charging

  • Charging current: Cannot 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 battery must carry on the charge in the ambient temperature scope which this specification book stipulated.
  • Uses the constant electric current and the constant voltage way charge, the prohibition reverse charges. If the battery positive electrode and the cathode meet instead, can damage the battery.

3.2 Discharging current

  • The discharging current does not have to surpass this specification book 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.

3.3 Electric discharge temperature

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

3.4 Over-discharges

  • After the short time excessively discharges charges immediately cannot affect the use, but the long time excessively discharges can cause the battery the performance, battery function losing. The battery long-term 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.

3.5 Storing the Batteries

  • The battery should store in the product specification book stipulation temperature range. If has surpasses above for six months the long time storage, suggested you should carry on additional charge to the battery.
