Section 2 - Hazards Identification
This contains lithium, organic solvent, and other combustible materials. For this reason, improper
handling of the battery could lead to distortion, leakage*, overheating, explosion, or fire and cause
human injury or equipment trouble. Please strictly observe safety instructions.
(* Leakage is defined as an unintended escape of liquid from a battery.)

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 consult
a 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 MediaExtinguisher 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
metal batteries are burning in a confined space use asmothering 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 Storage1) Handling● Never swallow.
Keep batteries at a place beyond the reach of an infant.
If a battery is accidentally swallowed, see Section 4 - First Aid Measures.

Coin Type ML Battery
Reference No. ML20240101-01e● Do not replace.
If you are an equipment manufacturer and need to replace the battery, please use a new one of
the same type of Maxell battery. Because this is a rechargeable battery, it is entirely different to aprimary battery even though they look alike. If a primary battery is installed in place of arechargeable battery, gas can be generated or the primary battery can be short-circuited throughcharging, leading to distortion, leakage, overheating, explosion or fire. Please design yourequipment so that the end user cannot replace the battery by mistake.
● Never use two or more batteries connected in series or in parallel.
This is because it is difficult to design circuits that comply with charging voltage or charging current
specified in circuit design warnings.
● Never reverse the positive and negative terminals when inserting in electrical equipment.
Inserting the battery incorrectly can lead to short-circuiting, charging or forced-discharging. Thiscan cause distortion, leakage, overheating, explosion or fire.
● Never short-circuit the battery.
Do not allow the positive and negative terminals to short-circuit. Never carry or store the battery
with metal objects such as necklaces or hairpins. Do not take multiple batteries out of the package
and stack or mix them when storing. Otherwise, this can lead to distortion, leakage, overheating,explosion or fire.
● Never heat.
Heating the battery to more than 100 deg. C can increase the internal pressure, causing distortion,leakage, overheating, explosion or fire.
● Never expose to naked flames.
Exposing to naked flames can cause the lithium metal to melt, causing the battery to catch fire andexplode.
● Never disassemble or deform.
Disassembly or deforming the battery can cause leakage, overheating, explosion or fire due tointernal short-circuits.
● Never weld the terminals or weld wire to the body of the battery.
The heat of welding or soldering can cause the lithium to melt or cause damage to the insulating
material in the battery. This can cause distortion, leakage, overheating, explosion or fire.
● Never touch liquid leaking from a battery.
If the liquid enters the eyes or mouth, see Section 4 - First Aid Measures.
● Never allow battery liquid to come into contact with a naked flame.
If leakage or a strong odor is detected, keep the battery away from all naked flames. The leaked
liquid is inflammable.
● Never attach a battery to the skin.
Attaching a battery to the skin using tape, etc. should be avoided. Moisture from the skin can cause
battery discharge, which can produce certain chemical substances that burn the skin.
2) Storage
Never let the battery contact with water. Never store the battery in hot and high humid place.

NASection 9 - Physical/Chemical Characteristics
Coin shape with rechargeable cell of 3V 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.
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 condition
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.
Section 14 - Transportation Information
1) Shipping Name (UN Number): Lithium metal batteries (UN3090)
Lithium metal batteries packed with equipment (UN3091)
