1. PRODUCT INFORMATION
Product Name: Lithium Ion Rechargeable Battery Pack
Model No.: LES2404GAHI
Cell: NCR18650GA
Rating: 25.2V/13.2Ah/336Wh
IATA Battery type code:
UN 3480 - Lithium Ion Batteries

2. HAZARDS IDENTIFICATION
For the battery cell, chemical materials are stored in a hermetically sealed metal or metal laminated plastic
case, designed to withstand temperatures and pressures encountered during normal use. As a result, during
normal use, there are no physical hazards such as ignition, explosion and chemical hazards due to leakageof battery contents.
However, if exposed to a fire, added mechanical shocks, decomposed, added electric stress by miss-use, thegas release vent will be operated. The battery cell case will be breached at the extreme, hazardous materials
may be released.
Also, if it is heated strongly by surrounding fires or the like, there is a possibility that irritating or harmful
gas may be generated.
・GHS classification: Not available(This product is outside the scope of GHS system since it's considered as an "article".)・Most important hazard and effects
Human health effects:
Inhalation: The steam of the electrolyte has an anesthesia action and stimulates a respiratory tract.
Skin contact: The steam of the electrolyte stimulates a skin. The electrolyte skin contact causes a sore andstimulation on the skin.
Eye contact: The steam of the electrolyte stimulates eyes. The electrolyte eye contact causes a soreand stimulation on the eye. Especially, substance that causes a strong inflammation of the eyes iscontained.
Environmental effects: Since a battery cell remains in the environment, do not throw out it into theenvironment.
・Specific hazards:
If the electrolyte contacts with water, it will generate detrimental hydrogen fluoride.
Since the leaked electrolyte is inflammable liquid, do not bring close to fire.

4. FIRST-AID MEASURES
Spilled internal cell materials
・Inhalation:
Make the victim blow his/her nose, gargle. Seek medical attention if necessary.
・Skin contact:
Remove contaminated clothes and shoes immediately. Wash extraneous matter or contact region withsoap and plenty of water immediately.
・Eye contact:
Do not rub one’s eyes. Immediately flush eyes with water continuously for at least 15 minutes. Seek
medical attention immediately.
A battery cell and spilled internal cell materials
・Ingestion:
Wash out mouth thoroughly. Do not make the victim vomit, unless instructed by medical personnel. Seek
medical attention immediately.
5. FIRE-FIGHTING MEASURE
・Suitable extinguishing media: Plenty of water, carbon dioxide gas, nitrogen gas, chemical powder fire
extinguishing medium and fire foam.
・Specific hazards: Corrosive gas may be emitted during fire.
・Specific methods of fire-fighting: When the battery burns with other combustibles simultaneously, takefire-extinguishing method which correspond to the combustibles. Extinguish a fire from the windward asmuch as possible.

・Special protective equipment for firefighters: Refer to Section 8-EXPOSURE CONTROLS/PERSONALPROTECTION (WHEN THE ELECTROLYTE LEAKS)
6. ACCIDENTAL RELEASE MEASURES
Spilled internal cell materials, such as electrolyte leaked from a battery cell, are carefully dealt withaccording to the followings.
・Precautions for human body:
Remove spilled materials with protective equipment (refer to Section 8-EXPOSURE CONTROLS/PERSONAL PROTECTION (WHEN THE ELECTROLYTE LEAKS)). Do not inhale the gas as much aspossible. Moreover, avoid touching with as much as possible.
・Environmental precautions: Do not throw out into the environment.
・Method of cleaning up: The spilled solids are put into a container. The leaked place is wiped off with drycloth.
・Prevention of secondary hazards: Avoid re-scattering. Do not bring the collected materials close to fire.
7. HANDLING AND STORAGE
・Handling suggestions
・Do not connect the positive terminal to the negative terminal with electrical wire or chain.
・Avoid polarity reverse connection when installing the battery to an instrument.
・Do not wet the battery with water, seawater, drink or acid; or expose to strong oxidizer.
・Do not damage or remove the external tube.
・Keep the battery away from heat and fire.
・Do not disassemble or reconstruct the battery; or solder the battery directly.
・Do not give a mechanical shock or deform.
・Do not use unauthorized charger or other charging method. Terminate charging when the charging
process doesn’t end within specified time.
・Storage・Do not store the battery with metalware, water, seawater, strong acid or strong oxidizer.
・Make the charge amount less than or equal to 50% then store at -20~40 degree C in a dry (humidity:45~85%) place.
Since deterioration will be faster in the high temperature range than in the low temperature range, so do
not keep it in the high temperature range beyond the period that is specified by the seller or owner.
・Use insulative and adequately strong packaging material to prevent short circuit between positive andnegative terminal when the packaging breaks during normal handling. Do not use conductive or easy tobreak packaging material..
8. EXPOSURE CONTROLS / PERSONAL PROTECTION (WHEN THE ELECTROLYTE LEAKS)・Control parameters
ACGIH has not been mentioned control parameter of electrolyte.
・Personal protective equipment
Respiratory protection: Respirator with air cylinder, dust mask
Hand protection: Protective gloves
Eye protection: Goggle or protective glasses designed to protect against liquid splashes
Skin and body protection: Working clothes with long sleeve and long trousers
