SECTION IV - HEALTH HAZARD DATA - (Continued)
Skin Absorption:
N-methyl pyrrolidinone, ethylene carbonate, ethyl methyl carbonate, dimethyl carbonate, and biphenyl may be
absorbed through the skin causing localized inflammation.
Skin Contact:
Contents of an open battery can cause skin irritation and/or chemical burns. Remove contaminated clothing and
wash skin with soap and water. If a chemical burn occurs or if irritation persists, seek medical attention.
Eye Contact:
Contents of an open battery can cause severe irritation and chemical burns. Immediately flush eyes thoroughly with
water for at least 15 minutes, lifting upper and lower lids, until no evidence of the chemical remains. Seek medical
attention.
Note: Acetylene black and cobalt compounds are listed as possible carcinogens by the International Agency for
Research on Cancer (IARC).
SECTION V - PRECAUTIONS FOR SAFE HANDLING AND USE
Storage:
The lithium ion battery should be between 25% and 75% of full charge when stored for a long period of time. Store in
a cool, dry, well-ventilated area. Elevated temperatures can result in loss of battery performance, leakage, or rust. Do
not expose the battery to open flames.
Mechanical Containment:
Containment of this battery in a manner that obstructs or defeats the safety vent or electrical disconnect mechanisms
designed into this battery can result in fire and/or explosion and cause personal injury and device damage. This
battery is not designed to be potted, enclosed in hermetic over packaging, or sealed by any means that prevents free
operation of the designed safety mechanisms.
Handling:
Do not expose the battery to excessive physical shock or vibration. Short circuiting should be avoided, however,
accidental short circuiting for a few seconds will not seriously affect the battery. Prolonged short circuits will cause
the battery to rapidly lose energy, could generate enough heat to burn skin, and may cause the safety release vents
of the enclosed cells to open. Sources of short circuits include jumbled batteries in bulk containers, coins, metal
jewelry, metal covered tables, or metal belts used for assembly of batteries in devices. To minimize risk of short
circuiting, the protective case supplied with the battery should be used to cover the terminals when transporting or
storing the battery. Do not disassemble or deform the battery. Should an individual cell within a battery become
ruptured, do not allow contact with water.
If soldering or welding to the battery is required, use of tabbed batteries is recommended. Soldering directly to the
cell can damage the battery safety seal, cause internal damage or short circuit the cell.
Charging:
This battery is made to be charged many times. Use an approved battery charger. Never use a modified or damaged
battery charger. Do not charge for over 180 minutes or repeat charging without intermittent discharging. A backup
charge termination based on time is recommended to prevent overcharging. The charging temperature should be
between 0°C and 50°C (32°F and 120°F). The battery pack will normally warm during charging.
Charging Voltages and Currents:
Charging voltages are prevented from exceeding the specified limits by an internal battery protection circuit.
Never use a battery which shows signs of a damaged protection circuit or broken case. (Such damage to the
protection circuit may be indicated by voltages at the battery terminals outside of their specified ranges.) Adhere to
all specified charging and discharging voltages and currents. Do not use battery if its voltage drops below the
specified minimum voltage.
Labeling:
If the label or package warnings are not visible, it is important to provide a package and/or device label stating:
WARNING: CHARGE ONLY WITH SPECIFIED CHARGERS ACCORDING TO DEVICE MANUFACTURER’S
INSTRUCTIONS. DO NOT OPEN BATTERY, DISPOSE OF IN FIRE, OR SHORT CIRCUIT - MAY IGNITE,
EXPLODE, LEAK, OR GET HOT CAUSING PERSONAL INJURY.
Disposal:
Dispose in accordance with all applicable federal, state, and local regulations.
