They are all lithium chemistry batteries with a nominal voltage of around 3.0 volts and a capacity ranging around 1000-1500 mAh. You will see a longer single-use life with the non-rechargeable version, but will save money in the long run using the rechargeable CR2 battery. These batteries are all interchangeable, and there is no operational difference between them. These rechargeable versions of the CR2 battery tend to have a slightly lower capacity (lower mAh) than the non-rechargeable versions, but will still fit in and power the same devices. Rechargeable or secondary versions of the CR2 battery are the 15270 battery and the 15266 battery. These batteries are all direct replacements for the CR2 battery, and are all considered primary or non-rechargeable batteries. What Battery Is Equivalent To The CR123A Battery?ĭirect replacements and equivalents for the CR2 battery could be, DLCR2, KCR2, ECR2 1CR2, and 5046LC. Basically, how long your CR2 battery will last depends on what you need it to do. For a more passive usage, such as in a home security alarm panel, service life can be over a year with the right conditions. For a frequent application that requires large amounts of energy, such as for a high lumen flashlight, a CR2 battery could last less than a month. 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. How long a CR2 battery lasts depends greatly on the manufacturing quality and the application of the battery. Using an incorrect or incompatible charger for your CR2 battery can cause the battery malfunction or not work at all. Even when using a well made rechargeable-battery, it is important to use the correct charger to ensure no issues occur. It is very important that you determine if a CR2 battery is a “primary battery” or a “secondary battery.” Attempting to recharge a non-rechargeable battery (especially a lithium battery) can cause a fire, explosion, or destruction of your charger/device. Rechargeable batteries are also known as “secondary batteries” while non-rechargeable, or single-use CR2 batteries, and known as “primary batteries”. Usually the label of a CR2 battery will indicate if that specific battery is rechargeable or not.
