Seizaiken Watch Batteries
'Every Moment SII's Legacy Grows.'

SII Factory, Japan
Seiko Instruments Inc. started out as a timepiece manufacturer. And every moment along the way, their technological expertise has grown deeper and wider. Miniaturize. Reduce. Use resources efficiently. Make thing lighter to wear or hold. This kind of thinking became encoded into SII's DNA. And now this DNA is evolving to include advanced electronic components, networking equipment, mobile information devices, and a multitude of other realms.
- Micromechatronics and Nanotechnology
SII combines advanced microtechnology with nano-level fabrication techniques to create revolutionary new devices.
- Energy Management
The efficient control of materials and power is the key to developing "dream" devices and efficient production processes, saving space and time.
- Network Solutions
A fusion of small information devices, networks, and content will change the way people live.
SII's DNA will carry the company's core strengths into the future to emerge both in ways we envision and in ways yet to be imagined.

Why Choose Seizaiken Batteries Over The Competition?
General Information
SII Micro Parts Ltd. has commercialized a highly reliable silver oxide battery in response to quartz watches. Since then the company has expanded its microbattery business. With rapid progress in LSI technologies, highly advanced microbatteries are now being strongly demanded for sophisticated electronic instruments and equipment. The company continues its best efforts to develop high performance microbatteries which meet any users' needs and requirements.
SIIMP aims at continuously developing higher performance micro batteries and at widening their product lineup. Please don't hesitate to contact them.
Features of Seizaiken Batteries
- Superior Leakage Resistance
Electrolytic leakage may lower the contact with terminals of the electronic instruments which use microbatteries. This interrupts the stable operations. Special sealing materials and processing technologies are employed in the manufacture of out batteries.
- Large Capacity
In order to extend the operating time of the machinery and equipment with-in the limited battery space, batteries need large capacity.
Our microbatteries have large capacity It is obtained by our original design technologies and by use of high purity materials.
- Stable Operating Voltage
The battery voltage depends on the temperature and the depth of discharge. Since the change of the voltage affects characteristics of machinery and equipment, the operating voltage must be stable. Our microbatteries have a stable operating voltage over a wide temperature range and in a depth of discharge.
- High Reliability
Batteries are required to have high performance in any event, that is, high reliability. Our microbatteries are manufactured under our high quality control. Only batteries with high quality are delivered to customers.
