CR uses lithium batteries: Small lithium batteries are very commonly used in portable electronic devices such as PDAs, watches, camcorders, digital cameras, thermometers, calculators, laptop BIOS, communication equipment, remote control door locks. . CR lithium manganese battery features: 1 high voltage and high energy density lithium - manganese dioxide battery voltage up to 3V or more, twice the ordinary batteries, which use electrical appliances, it means that the power supply can save space and reduce the weight. 2 excellent discharge performance even after long-term discharge, it remains stable operating voltage, which greatly improved the degree of reliability of the use of electrical appliances to achieve maintenance-free (basically having to replace the batteries). 3 superior temperature characteristics of high quality, good conductive properties of the application of organic electrolyte solution, the battery can work normally in the temperature range of -20 ℃ ~ 60 ℃, through a special process and formula, but also to meet the -40 ~ 80 ℃ operating temperature requirements. 4 good barrier properties and reliable sealing structure and the use of high quality liquid and electrically positive and negative electrode active material, the battery has excellent barrier properties. 5 operating characteristics and long life due to the effect of organic and lithium in the lithium anode surface to form a protective layer, which is the performance of the lithium battery can be maintained for a long time constant of the underlying causes, plus precise, reliable battery and a sealing structure using a high stability of the active substance, the self-discharge of the battery capacity drop rate can be controlled to less than 2% level.
