SII @ SEIZAIKEN SILVER OXIDE BATTERY im We value the "takumi" spirit. Seiko Instruments Inc. SEIZAIKEN SILVER OXIDE BATTERY High Quality Slls mercury-free silver oxide batteries are manufactured in a high-tech clean room environment in a newly constructed factory. This facility was specifically designed for the manufacturing of ultra precision electronic devices and incorporates all new equipment. Within the clean room environment SIl has eliminated contamination allowing us to ensure consistent quality. Advanced Technology Until recently, a small amount of mercury was included in the chemical compound of the silver oxide battery to suppress the possible generation of hydrogen gas should the zinc-based negative electrode corrode. If this hydrogen gas is generated, leakage resistance and storage stability of the battery will deteriorate and a possibility of swelling may occur. SII developed and incorporated the following two technologies in our no mercury added silver oxide batteries: ]. Use of high-corrosion resistance zinc alloy 2. Addition of a high performance inhibitor in the electrolyte No Mercury & No Lead Added According to the European Union (EU) battery directive, the marketing of alkaline manganese batteries containing more than 0.025% of mercury by weight is prohibited due to mercury s hazardous effects on human health and our environment. However, coin cell batteries have been exempt from this prohibition due to the technical difficulty of battery manufacturers to develop a no mercury added silver oxide battery. Sll has overcome this challenge with our new SEIZAIKEN mercury free silver oxide battery. Furthermore, gradual reduction and separate disposal of batteries containing more than 0.4% lead (Pb) by weight was one of the objectives held by the member states of EU. SII has also achieved this goal. Voltage / V Retention of Capacity / % 100 Features Ecology The introduction and adoption of new technologies made it possible to avoid using mercury and lead, which are environmentally harmful. Excellent leakage resistance Other than eliminating the need for mercury in the compound, these batteries are manufactured to have excellent leakage resistance attained by our newly developed crimping structure. This is made possible by our new high-performance manufacturing machinery and process. High reliability Production in our high precision clean room environment thoroughly prevents contamination resulting in the most consistent, highest reliability battery.
