An electric battery is essentially a source of DC electrical energy. It converts stored chemical energy into electrical energy through an electrochemical process. This then provides a source of electromotive force to enable currents to flow in electric and electronic circuits. A typical battery consists of one or more voltaic cells. Microbattery.com has been selling batteries online for over 25 Years and has one of the widest variety of batteries available, including all types of the CR2battery, from a variety of world-renowned manufacturers.

CR2 batteries have a nominal diameter of 15.6 millimeters. The overall height is 27 millimeters. Its weight is 11 grams.Batteries gradually self-discharge even if not connected and delivering current. This is due to non-current-producing “side” chemical reactions that occur within the cell even when no load is applied. When the circuit is closed, the stronger attraction for the electrons by the cathode (e.g. manganese dioxide in primary lithium batteries) will pull the electrons from the anode (e.g. lithium metal) through the wire in the circuit to the cathode electrode. This battery chemical reaction, this flow of electrons through the wire, is electricity.

The fundamental principle in an electrochemical cell is spontaneous redox reactions in two electrodes separated by an electrolyte, which is a substance that is ionic conductive and electrically insulated. The annual self-discharge rate of CR2 battery at room temperature and normal humidity is less than 1% of the nominal capacity. Chemistry of Lithium Metal Batteries Primary lithium batteries have the lowest self-discharge rate hence the longest available shelf time, up to 10 years, and in temperatures up to 70. The first letter in the IEC standard system identifies the battery’s chemical composition. C is for lithium metal batteries (as CR2032). The characteristics that make lithium an exceptional electrode material for high energy density batteries include low electrode potential and very high conductivity. It is soft and malleable and can be extruded into thin foils. The Watson CR123A Rechargeable Lithium Battery (3V, 400mAh) is a rechargeable version of the disposable CR123A and is free of memory effects. It has excellent high-drain performance and can be charged up to 1000 times....1 x CR123A. 3. Is a 123 battery the same as a 3V?

Lithium-based primary cells are batteries that have metallic lithium as an anode. These types of batteries are also referred to as lithium-metal batteries. Note that disposable primary lithium batteries must be distinguished from secondary lithium-ion or lithium-polymer, which are rechargeable batteries. Lithium-ion batteries do not contain metallic lithium. If we go into detail, batteries convert chemical energy directly to electrical energy. For example, chemical energy can be stored in Zn or Li, which are high-energy metals because they are not stabilized by d-electron bonding, unlike transition metals. Because the CR2 batteries are chemically very stable, they still have 90% of their original capacity even after 10 years. The stability is the result of the combination of lithium and manganese dioxide. The long-lasting function of these batteries has been verified at all operating temperatures under low-load discharge conditions. Lithium Metal Batteries The CR2 battery is not the same as the CR123A battery. The CR2 battery is slightly shorter than the CR123A battery and will not fit in most applications that require a CR123A battery. In addition the CR123A battery will deliver on average about 50% more output than the CR2 battery, meaning that even if you did manage to seat a CR2 battery into a device that uses a CR123A, it would not be able deliver the full power required and your device will either function poorly or not at all. These batteries do share a few similarities in that they are both made using lithium manganese dioxide and they are both 3 volt batteries. In general, lithium metal batteries, such as the CR2 battery, have a very high energy density, double that of premium alkaline batteries. They also have high cell voltage, flat discharge characteristic, low self-discharge, a very long operating life (15 to 20 years for lithium thionyl chloride), and a wide operating temperature range ( -60 ° C to +85 ° C for lithium-sulfur dioxide), excellent durability, and small cell size.
