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.

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
Addition of a high performance inhibitor in the electrolyte
