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 to deliver the full power required and your device will either function poorly or not at all. They are not interchangeable, and CR123A will not fit most applications requiring a CR2 battery and vice versa. The CR2 battery is noticeably shorter than the CR123A battery. Keep in mind that the CR2 battery is not the same as the CR123A battery. You’ll see a longer single-use life with the non-rechargeable version but will save money, in the long run, using the rechargeable CR2 battery. Physically they are the same, and they’ll fit in and power the same devices. NOTE: Rechargeable versions of the CR2 battery tend to have a slightly lower capacity (lower mAh) than the non-rechargeable versions. In case you can’t find CR2 in stock, direct replacements and equivalents could be: DLCR2, KCR2, ECR2, 1CR2, and 5046LC.ĬR2 replacement non-rechargeable model: These batteries, DLCR2, KCR2, ECR2, 1CR2, and 5046LC are all direct replacements for the CR2 battery and are all considered primary or non-rechargeable batteries.ĬR2 replacement rechargeable model: Replacement for rechargeable or secondary versions of the CR2 battery are the 15270 and the 15266 battery. Basically, how long your CR2 battery will last depends on what you need it to do. If it is used in devices such as home security alarm panels, service life can be more than a year. If you’re using a battery for a frequent application that requires large amounts of energy, such as for a high lumen flashlight, a CR2 battery can’t last more than a month or two. Assuming that the battery is fresh and purchased from a reliable source, there is still a large range of service life depending on the usage. To answer the question: How long CR2 battery lasts?
