A few decades ago, we commercialized
a highly reliable silver oxide battery to meet
the requirement of quartz watch
development. Since then, we have expanded
our microbattery offering and technology to
support the increased diversity in electronic
products available today.
This brochure introduces manganese silicon
lithium rechargeable batteries, titanium
silicon lithium rechargeable batteries, and
reflowable capacitors.
We plan to continuously develop higher
performance microbatteries and widen our
products lineup to keep up with our
emerging technologies.
Please feel free to contact us with any
questions you may have.
1. Superior leakage resistance
Even a slight leakage from a battery may interfere with the connections
made by the battery terminals, resulting in unstable device operation.
Seiko Instruments Inc. offers micro batteries that are highly
leak-resistant due to special sealing materials and processing
technologies.
2. Large capacity
In order to extend the operating time of devices with limited battery
space, the market demands high volumetric efficiency.
We offer large-capacity microbatteries developed with proprietary
technology utilizing high-purity materials.
3. Stable operating voltage
Carefully compounded ingredients allow each of our micro batteries to
have a stable operating voltage over both a wide temperature range
and depth of discharge.
4. High reliability
Our micro batteries are manufactured under an integrated system
featuring strict quality control, which starts with component
manufacturing, through assembly and on to rigorous out-going
inspection.

At the end of FY2006, 100% of our products are certied as SII Green Products. In addition, 38 products are certied
as SII "High Grade" Green Products.
2. Reduction of Greenhouse Gas
• We practice various CO2 reduction measures like using Eco-machinery. Since 1997, we have successfully reduced a
total of 54,100 tons of CO2. We believe our efforts contribute to the prevention of global warming.
3. 3R Promotion Activity
• We have promoted the "reduce and reuse" activities and also promoted recycling at the end of the production pro-
cess. With these activities, we achieved "Zero-emission" in 2004. We have reduced the non-recyclable wastes to less
than 1 ton - less than 1% of our 1997 results.
4. Biodiversity Conservation
•
We endeavor to deepen our understanding on the relevancy between biodiversity and our business activities, and to con-
tribute to the conservation of biodiversity by participating local community activities.
5. Green Purchasing
• We adhere to a green purchasing campaign through the purchase of ingredients, manufacturing materials, and other
necessary products, whenever appropriate.
6. Green Life
•
With the participation of all of Micro-Energy Division members, we deploy a clean-up and beautication campaign in all
areas surrounding our factory once a year. In addition, we participate in the clean up activity at Hirose River once a year.
7. Conflict Minerals
•
Recognizing the international importance of conict minerals issue, we prohibit the use of such minerals.

Precautions for Your Safety
21
Micro Battery 2014-2015
Micro-Energy Division Lithium rechargeable batteries (MS, TS) contain flammable organic sol-
vents. For your safety, please follow the following precautions.
• 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.
• Pay attention to soldering by tips
Do no touch the battery by solder chips, when soldering another compo-
nents after equipping battery.
Keep any high temperature process away from battery.
• Pay attention to material of jig for pick and place
Use non-conductive material of jig for pick and place of batteries, for
short-circuit protect. If short-circuit of battery occurs, the voltage of bat-
tery drops down quickly but raises gradually.
• Pay attention to washing and drying
Some detergent or high temperature drying may cause deteriorate of bat-
tery. 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.
The SII Lithium rechargeable batteries can be transported being not
subject to the provisions of dangerous goods, if they meet the following
requirements.
(a) <Caution Label> Lithium battery handling label (IATA Dangerous
Goods Regulations Figure 7.4.I) must be put on each package.
(b) <Not Restricted Declaration> Each shipment must be accom-
panied with a document 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 the package is damaged,
and a telephone number for additional information.
Do not jumble batteries
Example Example of insulation
Insulating tape
Short-circuiting
discharge discharge
Contacting between batteries cause
short-circuiting such as above diagram.
• Do not charge by higher current or higher volt-
age than specified.
Doing so may generate gas inside the battery, resulting
swelling, re, heat generation or bursting.
• Do not heat, disassemble nor dispose of in fire
Doing so damages the insulation materials and may
cause re, heat generation, leakage or bursting.
• Do not solder directly to the battery
If soldering is performed directly to the battery, the battery
is heated up, consequently causing leakage, explosion or
re due to overheating from internal short-circuit.
• 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.
• Keep batteries out of children’s reach.
It is dangerous that children swallow the battery.
When you design mechanical hardware around the bat-
tery, please x the battery rmly in order to prevent chil-
dren 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.
• 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 re.
• Do not weld terminals to the battery
The heat by welding may cause fire, heat generation,
leakage or bursting.
We weld standard terminals under strictly controlled con-
ditions.
If you need to weld terminals to the battery, please consult
us in advance.
• Do not discharge by force
If the battery is discharged by direct connection to an ex-
ternal 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.
•
In case of leakage or a strange smell, keep away from
fire to prevent ignition of any leaked electrolyte.
• In case of disposal, insulate between (+) and (-)
of battery by an insulating material.
Jumbling batteries or with other metal materials cause
short-circuit. As a result, re, heat generation, leakage or
bursting may occur.
• If leaked liquid gets in the eyes, wash them with
clean water and consult a physician immediately.
• Do not use new and used batteries together. Do
not use different types of batteries together.
It may cause re, heat generation, leakage or bursting.
• If you connect two or more batteries in series or
parallel, please consult us in advance.

WARNING!
CAUTION!
Precautions for Your Safety
22 Micro Battery 2014-2015
Micro-Energy Division capacitors (XH, CPH, CPX) contain flammable organic solvents. For your
safety, please follow the following precautions.
• Do not charge by higher current or higher voltage than
specified.
Doing so may generate gas inside the capacitor, resulting in
swelling, re, heat generation or bursting.
• Do not reverse placement of (+) and (-)
SII capacitors have polarity. If the (+) and (-) side of the capacitor
is reverse inserted, it may cause short-circuit or over discharge of
the capacitor on some equipment and it may induce overheating,
explosion or re.
• Do not solder directly to the capacitor (for XH only)
If soldering is performed directly to the capacitor, the capacitor will
over heat and, consequently cause leakage, explosion or re due
to overheating from internal short-circuit.
• Keep capacitors out of children’s reach.
It is dangerous that children swallow the capacitor.
• If leaked liquid gets in the eyes, wash them with clean
water and consult a physician immediately.
• Do not use nor leave the capacitors in direct sunlight
nor in high-temperature areas.
It may cause re, heat generation, leakage or bursting.
• Do not make the capacitor airtight by sealing it with
adhesive agent or coating agent.
It may cause short-circuit because of generated and accumulated
electrolyte gas.
WARNING!
CAUTION!
When you design mechanical hardware around the capacitor,
please x the capacitor rmly in order to prevent children from
removing it.
When you store the capacitors, please keep the capacitors out of
children’s reach. If a capacitor is swallowed, consult a physician
immediately.
• Do not heat, disassemble nor dispose of in fire
Doing so damages the insulation materials and may cause re,
heat generation, leakage or bursting.
• Do not discharge by force
If the capacitor is discharged by direct connection to an external
power supply etc., voltage of the capacitor will decline lower than
0 volts (electrical reversal) and will cause the capacitor case to ex-
pand, overheat, leak, explode or burn.
• In case of leakage or a strange smell, keep away from
fire to prevent ignition of any leaked electrolyte.
• Do not use new and used capacitors together. Do not
use different types of capacitors together.
It may cause re, heat generation, leakage or bursting.
• If you connect two or more capacitors in series or par-
allel, please consult us in advance.
It may cause bursting or re due to unbalanced load or voltage.
• Keep capacitors away from direct sunlight, high tem-
perature and humidity.
It may cause heat generation or performance deterioration.
