over temperature and balancing) and Battery Charger




Precautions:



1.Do not reverse the position and negative terminals.


2.Do not connect the battery electrodes to an electrical outlet.


3.Do not discard the battery in fire or a heater.


4.Does not use or leave the battery near a heat source as fire or heater


5.Do not short circuit, over-charge or over-discharge the battery pack


6.Do not strike, trample or throw the battery.


7.Do not directly solder the battery and pierce the battery with a nail or other sharp objects


8.Do not short-circuit the battery by directly connecting the positive and negative terminals with metal objects.


9.Do not transport or store the battery together with metal objects such as hairpins, necklaces, etc.


10.Use the battery charger specifically for that purpose when recharging. Use a constant current, constant voltage


(CC/CV) lithium-ion (Li+) battery charge controller


11.Do not immerse the battery in water or seawater, and keep the battery in a cool dry surrounding if it stands by.


12.If shelve a long time suggested that the battery need for regular recharging (even if not use),must charge and


discharge for three months one time;
