Lithium batteries Handling Precautions for Safe Use

Lithium batteries contain combustible materials such as lithium metal, lithium alloy and organic solvent. Improper handling can lead to leakage, heat generation, explosion or fire. To prevent accidents, pay sufficient attention to the following precautions. Also refer to them when you are describing in your instruction manual how to handle lithium batteries used in your application. These batteries are not available for sale to individual customers. If you wish to replace the battery in your device, please contact the store where you purchased the device or the device manufacturer.

Thin-type primary and coin-type primary/rechargeable lithium batteries

WARNING
  1. Do not charge (Primary batteries: CF and CR series).
    When the battery is charged, gas is generated inside and it raises internal pressure, resulting in leakage, heat generation, explosion or fire.
  2. Do not charge with unspecified conditions (Rechargeable batteries: ML series)
    Doing so may generate gas inside the battery, resulting in leakage, heat generation, explosion or fire.
  3. Keep batteries out of the reach of children
    In case of ingestion of a cell or battery, seek medical assistance promptly. Swallowing coin cells or batteries can cause chemical burns, perforation of soft tissue, and in severe cases can cause death. They need to be removed immediately if swallowed.
  4. Do not throw batteries into fire. Do not heat or disassemble batteries.
    Doing so may damage insulation, which can lead to leakage, heat generation, explosion or fire.
  5. Do not use the battery with the ⊕ and ⊖ terminals reversed.
    Doing so may cause the battery to leak, overheat, rupture, or catch fire due to abnormal reactions during charging or short circuit.
  6. If leaked liquid gets in the eyes, it can cause eye injury.
    Wash the eye(s) with clean water and receive medical care immediately.
  7. If leaked liquid gets into the mouth, rinse the mouth well and consult with a doctor immediately.
  8. Do not connect the ⊕ and ⊖ of the battery with a wire, etc., and do not carry or store the battery with metal necklaces, hairpins, etc., as this may cause the batteries to short-circuit, resulting in excessive current flow and battery leakage, overheating, rupture, or fire.
  9. If this battery is leaking or has a strange odor, keep it away from fire immediately as the leaked electrolyte may ignite.
  10. Do not solder directly on the battery.
    Doing so may damage insulation, which can lead to leakage, heat generation, explosion or fire.
  11. Make sure to insulate battery terminals with vinyl tape when disposing of or storing them to avoid short circuit.
    Putting batteries together disorderly or in contact with metal objects may cause short-circuit, resulting in leakage, heat generation, explosion or fire.
  12. Do not use new and used batteries together. Do not use different types of batteries together.
    Difference in their characteristics may cause leakage, heat generation, explosion or fire.
  13. Do not stick batteries on the skin.
    Doing so may cause skin injury.
CAUTION
  1. Do not drop the battery, give it a strong shock, or deform it.
    Doing so may cause leakage, heat generation, explosion or fire.
  2. Avoid contact with water.
    Doing so may cause leakage, heat generation, explosion or fire.
  3. Make sure to insert batteries in the application so that the positive⊕and negative⊖ terminals may not come into contact with metal parts of the application.
  4. Read the application's instruction manual and precautions carefully before use.
    The specifications or performance of these batteries may not match some usages or types of application.
  5. Store and use the batteries away from direct sunlight, high temperature and high humidity
    Otherwise, it can lead to leakage, heat generation, explosion or fire. If stored or used in such environment, batteries may suffer from deteriorated performance and life.
  6. Do not use the batteries if you notice heat generation, deformation or other abnormal situations while using or storing them.
    These can lead to leakage, heat generation or explosion.
  7. For proper disposal of batteries, refer to local regulations.

Cylindrical-type primary lithium batteries

WARNING
  1. Do not charge.
    When the battery is charged, gas is generated inside and it raises internal pressure, resulting in leakage, heat generation, explosion or fire.
  2. Do not use batteries for unspecified purposes.
    DDifferent terminal structure may suffer from contact failure. Differences in specifications may damage the battery or application, which can lead to leakage, heat generation, explosion or fire.
  3. Do not throw batteries into fire. Do not heat or disassemble batteries.
    Doing so may damage insulation, which can lead to leakage, heat generation, explosion or fire.
  4. Do not insert batteries with the positive ⊕ and negative ⊖ polarities reversed.
    Make sure the polarities are in the right position when inserting the batteries into the application. When using 3 or more batteries, the application may operate even though one of the batteries is improperly inserted but this may cause leakage, heat generation, explosion or fire.
  5. If leaked liquid gets in the eyes, it can cause eye injury.
    Wash the eye(s) with clean water and receive medical care immediately.
  6. If leaked liquid gets into the mouth, rinse the mouth well and consult with a doctor immediately.
  7. Do not connect the (+) and (-) of the battery with a wire, etc., and do not carry or store the battery with metal necklaces, hairpins, etc., as this may cause the batteries to short-circuit, resulting in excessive current flow and battery leakage, overheating, rupture, or fire.
    Difference in their characteristics may cause leakage, heat generation, explosion or fire.
  8. If this battery is leaking or has a strange odor, keep it away from fire immediately as the leaked electrolyte may ignite.
  9. Do not use new and used batteries together. Do not use different types of batteries together.
    If the positive ⊕ and negative ⊖ terminals come into contact with metal objects, short circuit occurs and excessive current flows at once resulting in leakage, heat generation, explosion or fire. When carrying or storing the batteries, avoid direct contact with metal objects such as bracelets or key chains by putting them in a separate container.
  10. Do not solder directly on the battery.
    Doing so may damage insulation, which can lead to leakage, heat generation, explosion or fire.
  11. Do not remove or damage the outer label of the battery.
    Doing so may cause the battery to short-circuit, resulting in leakage, overheating, rupture, or fire.
  12. Do not drop the battery, give it a strong shock, or deform it.
    Doing so may cause the battery to leak, overheat, explode, or catch fire.
  13. Do not deform the battery in any way.
    Doing so may damage insulation or gas release vent resulting in leakage, heat generation, explosion or fire.
  14. Make sure to insulate battery terminals with vinyl tape when disposing of or storing them to avoid short circuit.
    Putting batteries together disorderly or in contact with metal objects may cause short-circuit, resulting in leakage, heat generation, explosion or fire.
CAUTION
  1. Do not use or leave the batteries exposed to heat such as a front of window in direct sunlight or inside a car under sunlight.
    Doing so may cause leakage, heat generation, explosion or fire.
  2. Avoid contact with water.
    Doing so may cause leakage, heat generation, explosion or fire.
  3. Read the application's instruction manual and precautions carefully before use.
    The specifications or performance of these batteries may not match some usages or types of application.
  4. Remove batteries from the application if you do not use it for a long time.
  5. Store and use the batteries away from direct sunlight, high temperature and high humidity.
    Otherwise, it can lead to leakage, heat generation, explosion or fire. If stored or used in such environment, batteries may suffer from deteriorated performance and life.
  6. Do not use the batteries if you notice heat generation, deformation or other abnormal situations while using or storing them.
    It can lead to leakage, heat generation or explosion.
  7. Check batteries inside emergency-use applications periodically.
    Applications may not work properly in emergency due to batteries' deterioration, or may be damaged by leakage.
  8. For proper disposal of batteries, refer to local regulations.
