Datasheet

●Do not throw the Battery into fire or heat it.
●Do not use the Battery with + and - in reversed.
●Do not connect + and - terminals with wire or other metal (Do not short-circuit the Battery.).
●Do not directly solder to the Battery.
●Do not allow the Battery to be immersed in or wetted with water or sea-water.
●Do not put the Battery into the microwave oven or high pressure container.
1) The discharge current should not exceed the designated current described in this specification.
If the discharge current exceeds the specified value, discharge capacity could be extremely deteriorated or the
battery could be heated.
2) The discharge temperature range should be the specified value in this specification.
●Do not put any combustibles around the Battery during storage.
●Do not store the Battery in places of high temperature or under direct sunlight.
1) When the Battery is charged, the specified charge method and current described in this document should be
applied.If charge current exceeds the upper limit of the specified range, characteristics and safety of the Battery could be
deteriorated, or it may cause heat, explosion and fire.
4. Prohibitions and Cautions in Discharging the Lithium-ion Battery
3) The battery shall be charged within the range of Operating Ambient Temperature in the Product Specification and the
battery temperature may not exceed 60℃ during charging.
5. Cautions for the Battery Storage
Store the Battery in the storage condition defined in this specification.
●Store the Battery in the state of discharge (remaining capacity: 20-30%), when the Battery is stored for a long
●The Battery is a chemical product utilizing a chemical reaction, so the performance will be deteriorated not
only through use but also with the passage of time even if it left unused.
●Do not store the Battery in high humidity or in the place which may expose the Battery to rain or water.
3) When the Battery is stored for a long term, the Battery could become over discharged due to self discharge.
The Battery with voltage less than over-discharge-protection-reset-voltage must be charged with small current in a
few minutes. If the Battery voltage is not recovered to over-discharge-reset-voltage after small current charging in a
few minutes, do not charge the Battery again.

1. Scope
Prohibitions and Cautions in Handling the Lithium-ion Battery Pack
1) Mishandling of the Battery may cause heat, explosion and fire. Be sure to observe the following.
2. General Prohibitions and Cautions in Handling the Lithium-ion Battery
tests in may be) Please consult YLE again. YLE is not responsible for the troubles caused by mishandling of the Battery
which is clearly against the instructions in this document. When YLE finds the new fact which requires modification in the
contents of this document, we will inform you again.
3. Prohibitions and Cautions in Charging the Lithium-ion Battery
●Do not pierce the Battery with a nail, strike it with a hammer, step on it or otherwise subject it to strong impact.
2) Never disassemble or modify the Battery. The safety mechanisms are incorporated in the Battery to prevent danger.
Damaged safety mechanism may cause heat, explosion and fire.
3) Do not leave the Battery in places of the high temperature like the side of a fire or stove or under strong direct
sunlight. This may cause heat, explosion and fire. In addition, performances and service life of the Battery may be
deteriorated.
4) Immediately stop using the Battery, if you notice heat, discoloration, deformation, damage on external tube, or
anything wrong, during use or storage of the Battery. Move the Battery away from a fire immediately when you notice
a foul odor due to leakage.
5) When electrolyte of the Battery splashes into the eyes, immediately flush the eyes thoroughly with clean water
without rubbing and take a medical treatment immediately. If appropriate procedures are not taken, this may cause
a loss of sight.
2) Charge voltage should be less than 4.2V. Even if you consider the voltage control accuracy, the maximum voltage of
the battery should be 4.25V. If the charge voltage exceeds the upper limit of the specified range, characteristics of the
battery could be remarkably deteriorated.
