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.
