Saftey

• Risks of electric shock

– Do not disassemble the battery pack.

– Do not touch the battery pack with wet hands.

– Do not expose the battery pack to moisture or liquids.

– Keep the battery pack away from children and animals.

• Risks of damage to the battery pack

– Do not allow the battery pack to come in contact with liquids.

– Do not subject the battery pack to high pressures.

– Do not place any objects on top of the battery pack.

Battery handling guide

• Use the battery pack only as directed.

• Do not use the battery pack if it is defective, appears cracked, broken or

otherwise damaged, or fails to operate.

• Do not attempt to open, disassemble, repair, tamper with, or modify the

battery pack. The battery pack is not user serviceable.

• To protect the battery pack and its components from damage when trans-

porting, handle with care.

• Do not impact, pull, drag or step on the battery pack. Do not subject it to

any strong force.

• Do not insert foreign objects into any part of the battery pack.

• Do not use cleaning solvents to clean the battery pack.

1.3 Response to emergency situations

The RESU battery pack comprises multiple batteries that are designed to pre-

vent hazards resulting from failures. However, LG Chem cannot guarantee

their absolute safety.

Leaking batteries

If the battery pack leaks electrolyte, avoid contact with the leaking liquid or

gas. Electrolyte is corrosive and contact may cause skin irritation and chemical

burns.

7

Saftey

If one is exposed to the leaked substance, do these actions:

Inhalation: Evacuate the contaminated area, and seek medical attention im-

mediately.

Eye contact: Rinse eyes with owing water for 15 minutes, and seek medical

attention immediately.

Skin contact: Wash the aected area thoroughly with soap and water, and

seek medical attention immediately.

Ingestion: Induce vomiting, and seek medical attention immediately.

Fire

In case there is a re, always have an ABC or carbon dioxide extin-

guisher.

WARNING

The battery pack may catch re when heated above 150°C.

If a re breaks out where the battery pack is installed, do these actions:

1. Extinguish the re before the battery pack catches re.

2. If it is impossible to extinguish the re but you have time, move the battery

pack to a safe area before it catches re.

3. If the battery pack has caught re, do not try to extinguish the re. Evac-

uate people immediately.

WARNING

If the battery catches re, it will produce noxious and poisonous gases. Do

not approach.

Wet batteries

If the battery pack is wet or submerged in water, do not try to access it. Contact

LG Chem or your distributor for technical assistance.

Saftey

Damaged batteries

Damaged batteries are dangerous and must be handled with extreme caution.

They are not t for use and may pose a danger to people or property.

If the battery pack seems to be damaged, pack it in its original container, and

then return it to LG Chem or your distributor.

CAUTION

Damaged batteries may leak electrolyte or produce ammable gas. If you

suspect such damage, immediately contact LG Chem for advice and infor-

mation.
