Section 5 - Fire Fighting Measures
Extinguishing Media Extinguisher of alkaline metal fire is effective.
Plenty of cold water is also effective to cool the surrounding area 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 batteries are burning in a confined space, use a smothering agent.
Fire fighting procedure Use self-contained breathing apparatus and full protective gear not to inhale harmful gas (e.g. carbon dioxide
or dry sand).
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
1) Handling
• Never swallow.
If a battery is accidentally swallowed, see Section 4 - First Aid Measures.
• Never charge.
The battery is not designed to be charged by any electrical source. Charging can generate gas and internal short-circuiting, leading 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 and explode.
• Never disassemble or deform.
Disassembly or deforming the battery can cause leakage, overheating, explosion or fire due to internal short-circuits.
• 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. This can 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 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 use different batteries together.
Using different batteries together, i.e. different types or old/used and new or those of different manufacturers, can cause distortion,
leakage, overheating, explosion or fire because of the differences in battery properties. Please consult Maxell before designing devices
that use two or more batteries connected in a series or parallel, even with the same battery type.
• 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.
