FEATURES
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.
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.
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.
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.

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 silver oxide
batteries, manganese silicon lithium
rechargeable batteries, titanium silicon
lithium rechargeable batteries, reflowable
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.
