Section 2 – Hazards Identification Including Emergency Overview
A lithium ion cell is normally stable under appropriate handling and storage conditions.
If a lithium ion cell generates abnormal heat, keep away from the cell to avoid inhaling internalmaterials. Chemicals utilized in lithium ion cells do have some toxicity and inhalation may cause
irritation.

Section 4 - First Aid Measures
None unless internal materials exposure. If contents are leaked out, observe following instructions.
Inhalation

Fumes can cause respiratory irritation. Remove to fresh air and consulta physician.

Skin

Immediately flush skin with plenty of water. If itch or irritation by chemicalburn persists, consult a physician.

Eyes

Immediately flush eye with plenty of water for at least 15 minutes.
Consult a physician immediately.

Ingestion

If swallowing a battery, consult a physician immediately.
If contents come into mouth, immediately rinse by plenty of water andconsult a physician.

Section 5 - Fire Fighting Measures
Extinguishing Media

Extinguisher of alkaline metal fire is effective.
Plenty of cold water is also effective to cool the surroundingarea and control the spread fire. But hydrogen gas may be
evolved by the reaction of water and lithium and it can form an
explosive mixture. Therefore in the case that lots of lithium ion
batteries are burning in a confined space use a smothering
agent (e.g. carbon dioxide or dry sand).

Fire fighting procedure

Use self-contained breathing apparatus and full protective
gear not to inhale harmful gas.

Section 6 - Accidental Release Measures
If the battery releases liquid, wipe it with a dry cloth.
Keep the battery away from fire or heat.
Section 7 - Handling and Storage
Handling:■ Do not swallow. Always keep the battery out of the reach of infants and young children toprevent it from being swallowed. If swallowed, consult a physician immediately.

CLB
Reference No. CLB20240101-01e■ Do not put the battery in a microwave oven or a pressure cooker. Sudden heat may damage
the seal of the battery and may cause overheating, explosion or fire.
■ Do not use the battery together with a primary battery such as a dry battery or other battery ofa different capacity, type and/or brand. In such a case, over-discharge during use or overcharge during charging may occur and abnormal chemical reactions may cause heatgeneration, explosion or fire from the battery.
■ Design your equipment so that the end user cannot replace the battery by mistake. If you arean equipment manufacturer and need to replace the battery, please use a new one of thesame type and same model as the existing one. Because this is a rechargeable battery, its
characteristics are completely different from other primary batteries (e.g. coin type lithium
manganese dioxide batteries: CR) or other secondary batteries (e.g. lithium manganesedioxide rechargeable batteries: ML) even though their shapes are alike. If a different battery is
installed in the circuit in place of a CLB battery, gas could be generated or the primary battery
could be short-circuited by charging. This could lead to distortion, leakage, overheating,explosion, or fire.
■ If you notice any unusual odor, heat, discoloration, deformation or any other characteristic
apart from what you are used to while using, charging or storing the battery, then take it out of
the equipment or charger, and avoid using it. Using it in such state may result in overheating,explosion or fire.
■ If the battery leaks or emits an unusual odor, remove it from the vicinity of any fire
immediately. The electrolyte may catch fire, which may cause explosion or fire.
■ Do not let leaked electrolyte come into contact with the eyes. In the event of such contact,flush the eyes with plenty of water immediately and consult a doctor. Otherwise prolonged
contact may cause serious injury.
■ When charging is not finished in the expected period of time, stop charging. Otherwise thebattery may cause overheating, explosion or fire.
Storage:・Never let the battery contact with water. Never store the battery in hot and high humid place.
・Charge the battery every 6 months to the amount specified by the manufacturer, even if the battery
is not used.

Section 9 – Physical/Chemical Characteristics
The appearance is a coin shape and it is a rechargeable cell with 3.7V or 3.8V nominal voltage.
Section 10 - Stability and Reactivity
Stability: Stable (Performance deterioration depends on circumstance.)
Incompatibility: Water
Hazardous polymerization: Will not occur.
Condition to avoid: See section 7, Do not heat above 100℃（212°F）
Hazardous Decomposition or Byproducts: Hydrogen (By moisture)
Section 11 - Toxicological Information
As the contents are sealed in the battery case, there is no toxicity.
Section 12 - Ecological Information
If the battery is disposed of on land or in water, the battery case may corrode and liquid leak fromthe battery. Ecological information has not been reported.
Section 13 - Disposal Consideration
The battery may be regulated by national or local regulation. Please follow the instructions of proper
regulation. As electric capacity is left in a discarded battery and it comes into contact with othermetals, it could lead to distortion, leakage, overheating, or explosion, so make sure to cover the (+)
and (-) terminals with friction tape or some other insulator before disposal.
