SII’s 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 SII has eliminated contamination allowing us to ensure consistent quality.

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.
