二氧化锰锂圆柱电池：个别规格 Manganese Dioxide Lithium Cylindrical Batteries: Individual Specifications

The is a 3V cylindrical-type Lithium Battery with 850mAh capacity. It has pressure contact terminals. It is ideally suited for use in all kinds of products where the trend is to achieve increasing miniaturization. Since the manganese dioxide that is chemically very stable is used for plus terminal as an active material, if preservation conditions are proper, 90% of capacity remains even after ten years storage. It employs organic electrolytes with minimum creeping so they are vastly superior in terms of leakage resistance under environmental changes.
