The batteries silver oxide of Murata, are suitable for powering small portable electronic devices, such as wristwatches, car keys, and many others. Silver oxide batteries maintain an almost constant nominal voltage during discharge until fully depleted. The silver content is very low, resulting in a low cost for the battery.
The substances contained in a small battery are capable of polluting 1 cubic meter of soil or 400 cubic meters of water. The battery may be empty, but it still contains significant components. For this reason, we must find specialized collection bins and recycle it, so that the "life cycle" of the battery can continue. This way, the basic elements are recycled and new batteries or other products are produced.
