Precautions for Your Safety
SII Lithium rechargeable batteries (MS, ML, TS) contain flammable organic solvents.
For your safety, please follow following prohibitions.
!
WARNING!
7. Do not weld terminals to the battery
1. Do not charge by high current or high voltage.
Doing so may generate gas inside the battery, resulting swelling, fire,
and heat generation or bursting.
2. Do not heat, disassemble nor dispose of in fire
Doing so damages the insulation materials and may cause catching
fire, heat generation, leakage or bursting.
The heat by welding may cause fire, heat generation, leakage or
bursting.
We weld standard terminals under strictly controlled conditions.
If you need to weld terminals to the battery, please consult us in
advance.
8. Do not discharge by force
3. Do not solder directly to the battery
If soldering is performed directly to the battery, the battery is heated
up, consequently cause leakage, explosion or fire due to overheating
from internal short-circuit.
4. Do not short.
If the (+) and (-) come into contact with metal materials, short-circuit
occurs. As a result, fire, heat generation, leakage or bursting may
occur.
5. Keep batteries out of children’s reach.
It is dangerous that children swallow the battery.
When you design mechanical hardware around the battery, please fix
the battery firmly in order to prevent children from removing it.
When you store the batteries, please keep the batteries out of
children’s reach.
If a battery is swallowed, consult a physician immediately.
If the battery is discharged by direct connection to an external power
supply etc., voltage of the battery will decline lower than 0 volts
(electrical reversal) and will cause the battery case to expand,
overheat, leak, explode or burn.
9. In case of leakage or a strange-smell; keep away from fire to
prevent ignition of any leaked electrolyte.
10. In case of disposal, insulate between (+) and (-) of battery by
an insulating material.
Jumbling batteries or with other metal materials cause short-circuiting.
As a result, fire, heat generation, leakage or bursting may occur.
Do not jumble batteries
Short-circuiting
6. Do not reverse placement of (+) and (-)
If the (+) and (-) side of the battery is reverse inserted, it may cause a
short-circuit or over discharge of the battery on some equipment and
it may induce overheating, explosion or fire.
Example of insulation
Insulating tape
discharge
discharge
Contacting between batteries cause shortcircuiting such as above diagram.
!
CAUTION!
1. If leaked liquids gets in the eyes, wash them with clean water
and consult a physician immediately.
2. Do not use new and used batteries together. Do not use
different types of batteries together.
It may cause fire, heat generation, leakage or bursting.
3. If you connect two or more batteries in series or parallel,
please consult us in advance.
It may cause bursting or fire due to unbalanced load or voltage.
4. Do not use nor leave the batteries in direct sunlight, nor in
high-temperature areas.
It may cause fire, heat generation, leakage or bursting.
5. Do not apply strong pressure to the batteries nor handle
roughly.
It may cause fire, heat generation, leakage or bursting.
6. Avoid contact with water.
It may cause heat generation.
7. Keep batteries away from direct sunlight, high temperature
and humidity.
It may cause heat generation or performance deterioration.
8. Do not make batteries airtight by sealing it with adhesive
agent or coating agent.
It may cause short-circuit because of generated and accumulated
electrolyte gas.
For prevention the performance of battery
3. Pay attention to material of jig for pick and place
1. Pay attention to mat or sheet for ESD
Battery with tabs or battery on PCB may short circuit on the mat for ESD.
As a result, the voltage of the cell is reduced.
2. Pay attention to soldering by iron tips
Use non-conductive material of jig for pick and place of batteries in order
to prevent short-circuit. If short circuit of battery is occurred, the voltage of
battery drops down quickly but raises gradually.
4. Pay attention to washing and drying
Do not touch the battery by soldering iron tips directly.
Keep any high temperature process away from battery.
Some detergent or high temperature drying cause deteriorates of battery.
If you need to wash batteries, consult us.
International Transportation and Disposal
International Air / Marine / Ground Transportation
Regarding the transport of Lithium battery, organizations like IATA, ICAO, IMO,
DOT have determined transport regulations, based on the United Nations
Regulations.
Regarding air transport, SII Lithium rechargeable batteries can be transported
being not subject to the provisions of dangerous goods, if the transportations
meet the following requirements.
Please contact us for more details.
Regarding marine or ground transport, please contact us for more details, too.
(a) Batteries are separated each other, and are packed
in strong packaging so as to prevent short-circuit.
(b) Lithium battery handling label (IATA prescribed),
indicating that the packages contain Lithium batteries, that the packages must
be handled with care, and that special procedures should be followed in the
event that the package is damaged, and a telephone number for additional
information, must be put on each package.
(c) “CARGO AIRCRAFT ONLY” Label must be put on each
package.
(d) Each shipment must be accompanied with
a document indicating that the packages contain Lithium batteries, that the
packages must be handled with care, that it must not be transported by
passenger flight, and that special procedures should be followed in the event
that the package is damaged, and a telephone number for additional
information.
(e) Each package is capable of withstanding a
1.2m drop test in any orientation without damage to batteries contained.
(f) Net weight of one package may not exceed 2.5 kg.
(g) The shipment must be "one carton per
one shipment" to be shipped as “Non-dangerous goods”.
“One shipment” means one airway bill = one invoice.
【Transport as dangerous goods】
When you transport SII’s Lithium rechargeable batteries by “more than one
carton per one shipment”, you will have to arrange it as "Dangerous goods".
It requires special procedures, like “Class 9 dangerous goods Label” on carton,
and “dangerous goods declaration”.
Disposal
Recently environmental protection regulations have increased and battery
disposals are regulated globally.
Such regulations are different in each country, state, and municipality.
Please consult your local authorities regarding the specific regulations in your
area.
