12. Cautions

1),Read the instructions on your device before installing batteries. Only use the size and type of battery specified in the instructions.

2),Keep the contact point or surface clean .Check the contact point or surface to pr event the short circuit of the battery

3),Insert the batteries properly. Follow the symbols showing the correct way to posi tion the positive (+) and negative (-) ends of the batteries.

4),Don’t mix old and new batteries, or mix different types or makes of batteries. 5),Don’t heat,charge,crush, puncture, or otherwise damage batteries, This can result in leakage or rupture.

6),Don’t dispose of batteries in a fire — they may leak or rupture

7),Don’t dispose of batteries in water.

8),Don’t stack batteries.

9),Don’t disassemble the battery.

10),Keep in a dry and cool place. Storage at place with high temperature( over +6 0’C )or low temperature( under -20’C) or place with humidity over 75% will lead to the capacity loss , derated electric performance and also safety problem.

11),Keep away from the strong acid, alkali, oxide, and other corrosive materials. 12),Keep batteries out of reach of children.

 

13),Pay attention to the expire date of the battery.

14),Do not dispose of used battery in natural environment ,like river ,lake, sea and land .Do not bury the used in battery the soil .

13. Handling instruction for emergency

1),If short circuit, disconnect the wire or other conductor with the battery

2),If installed battery with wrong direction, take out battery and follow the symbols s howing the correct way to position the positive (+) and negative (-) ends of the batt eries.

3),If your skin get contact with the electrolyte, wash with water immediately.

4),If bare batteries stacked (especially with very large quantity), which may generat e heat, or even explosion, please separate them immediately.

5),If swallowed, contact a physician immediately.

6),If fire or explosion happened, cover them with sand or soil to put out the fire . Dry powder fire extinguisher can be used to put out the fire. Do not use water . 7),Avoid inhaling the irritative gas, which generated by the fire or explosion of batte

ry .Clothes, towel or cotton material can be used to prevent inhaling, wet clothes or towel will be better. If inhaled the irritative gas ,please contact a physician.
