Note for battery pack use:


 


1. Read the battery instructions carefully, use the recommended battery, and operate in accordance with the operating procedures;


 


2. Check that electrical and battery contacts are clean, wipe with wet cloth when necessary, dry and pack in the correct polarity direction;


 


3. Do not let children replace batteries without adult custody. Small batteries such as AAA should be kept out of reach of children;


 


4. Do not mix new, old or different types of batteries, especially dry batteries and rechargeable batteries;


 


5. Do not attempt to regenerate a battery by heating, charging, or other means to avoid danger;


 


6. Do not short-circuit the rechargeable battery. Otherwise, it will damage the battery and cause the battery to burn. Do not heat the battery or throw it into water or fire. Putting the battery into the water will invalidate the battery. Putting the battery into the fire will cause the battery to break down, or burst into a violent chemical reaction, or produce some harmful gases and smoke.


 


8. Do not remove the battery or try to penetrate the battery with sharp objects because the electrolyte inside the battery can harm skin and clothing;


 


9. After the use of electrical appliances should be disconnected power switch, so as to avoid heating and fire;


 


10. The battery should be removed from long term unused appliances, stored after emptying, and charged and discharged every 3 months or so;


 


11. Battery should be kept in a cool, dry place, avoid direct sunlight;


 


12. Nickel charger and lithium charger can not be mixed;


 


13. Cannot use the battery, the high temperature produced during welding will damage the internal structure of the battery, may make the battery unusable, or even dangerous;


 


 14. Can not reverse charge, reverse charge is equivalent to overdischarge, overdischarge will cause adverse reactions in the battery and lead to serious damage to the battery, producing a large number of gases, which may cause chemical leakage of the rechargeable battery;


 


15. Do not put the battery under Rain Water, Rain Water can conduct electricity, when the battery under the Rain Water, it is likely to occur short circuit, so that the battery instant large current discharge and hot, will damage the battery or risk;
