The table below compares and contrasts the most important characteristics of several popular CR2 battery models.Ī nominal voltage of 3.0 volts, a cutoff voltage of 2.0 volts, and a very low self-discharge rate are all included in the chart.Īlso, while the 'official' operating temperature range is usually between -40☌ and +70☌, it is important to remember that the performance of these batteries is temperature-dependent, and they perform best at room temperatures (20-25☌), with temperatures between -10☌ and 50☌ being avoided if at all possible.ġ200 mA, 3s/7s, 760 cycles, down to 1.8Vġ800 mA, 3s/7s, 400 cycles, down to 1.8Vĩ00 mA, 3s/27s, 900 cycles, down to 1.6Vĩ00 mA, 3s/27s, 1000 cycles, down to 1.8Vĩ00 mA, 3s/27s, 900 cycles, down to 1.5VĪs can be seen, the CR2 battery can easily deliver continuous currents of 10-20 mA. Technical Specifications Of The CR2 Battery Ⅱ CR2 Lithium Battery Replacement 2.1 CR2 Batteries Cross Reference Chart The shelf life of CR2 batteries varies depending on the model and brand, but it is typically 3+ years, with some brands having 10+ year shelf lives, making them ideal for standby or emergency devices (panic lights, EDC flashlights, medical equipment, etc.).ĬR2 batteries are fairly common, and most reputable brands offer them, so finding good ones from online shops and stores should not be a problem. Manganese-dioxide lithium 15.6 x 27 mm non-rechargeable cylindrical batteries are the most common, with carbon-monofluoride lithium 15.6 x 27 mm non-rechargeable cylindrical batteries ('BR2 battery') being extremely rare. The 1CR2, DL-CR2, DLCR2, 5046LC, CR15H270, EL1CR2, KCR2, and other CR2 battery equivalents are commonly used. Many manufacturers use the standard CR2 label but add a letter or two to emphasize the brand, for example, when labeling their batteries. The CR2 battery typically has a capacity of 800 to 850 mAh, though this varies depending on the device's cutoff voltage and drain conditions (current strength, temperature, and similar). The CR2 battery has a diameter of 15.6 mm and a height of 27 mm (1.063 inches). It is a non-rechargeable lithium battery. The CR2 battery has a nominal voltage of 3.0 volts and a cutoff voltage of 2.0 volts. This article will provide you with all of the information you need to know about the CR2 battery.ĬR2 lithium battery 1.2 CR 2 Battery Features and Specifications
Panasonic, D uracell, and Energizer are just a few of the big and small brands that make them. Because of its numerous applications, this battery is extremely popular and, as a result, can be difficult to locate.
They're commonly found in cameras that require a high-capacity lithium battery, as well as in a variety of industrial applications. These batteries can be used in a wide range of situations. In simple terms, the CR2 battery resembles a smaller version of a D Cell Battery, or, to put it another way, a can. The CR2 battery is a cylindrical lithium cell with measurements of 27mm x 15.6mm. Ⅰ CR2 Battery Basics 1.1 What is a CR2 Battery? The Energizer brand, for example, puts more strain on its batteries than other brands, ensuring comparative endurance under extreme conditions. A CR2 lithium battery's shelf life is determined by its model and manufacturer. This is due to their small size, which makes them ideal for electronic devices on the go. This is the type of battery used in cameras (such as the CR2). A standard cylindrical lithium battery is referred to as a CR2. The CR2 battery, which is found in cameras,weapon-mounted lights, golf rangefinders, EDC flashlights, and security devices, is revered around the world.
