Dimensions, Weight and Capacity of CR123a Battery The CR123a Battery is known for its high voltage, energy density, durability, and stable operation. Two CR123a batteries are often used as a backup power-source for flashlights that use 18650 rechargeable cells. They’re usually button top, and are primary (non-rechargeable) batteries. 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.Ī CR123a battery is a 3V lithium-metal-based cylindrical cell that can be used as a flashlight or camera battery. A typical battery consists of one or more voltaic cells. This then provides a source of electromotive force to enable currents to flow in electric and electronic circuits. It converts stored chemical energy into electrical energy through an electrochemical process. Li (s) + Mn IVO 2(s) ⇌ Mn IIIO 2(Li +) Īn electric battery is essentially a source of DC electrical energy. 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. In general, lithium metal batteries, such as the CR123a battery, have a very high energy density, double that of premium alkaline batteries. A full line up for use in a wide variety of applications.
