As a result, even when we can fit the device using CR123 with CR2, it may operate poorly or not work as the current supplied to the device is insufficient. The CR2 has a typical capacity of 800 – 850mAH, while the CR123 is almost twice larger, from 1500 to 2000mAH. For example, 800mAH means 800mA of current can be generated through chemistry interaction per hour. In simple terms, capacity refers to the storage amounts of energy generated by a certain power unit. In other words, they’re incompatible sizes. CR123 is higher, so CR-2 cannot replace the electronic devices that work with CR123. Sometimes, we may misunderstand that they have the same diameter when glancing. In other words, the CR123 is bigger in diameter and height. The CR2 is 27mm x 15.6mm, while the other is 34.5mm x 17mm. The first thing that makes those models different is their dimensions. From there, we can choose the best for us! Dimension We’ll examine the most important aspects of these two types of batteries. For example, the capacity requirement of the device. Therefore, rather than choosing the best, let’s select the most appropriate to our conditions. They are all the top common types on the market. It’s difficult to accurately define which one is better as there are certain differences between them. However, they’re more economical as we can use them multiple times. Their drawback is that they offer a lower capacity compared to single-use ones. Moreover, there are models 1520, which are rechargeable versions for CR2 equivalents. They are even all trusted, thanks to high accessibility, flexibility, and stability. They are all non-rechargeable versions or called primary batteries, offering a stable operation with long use life. Those above options can be directly replaced with CR2.
Hereafter is a list of battery equivalent and replacement options and related things that we can count on. Because there is a flood of information outside, making us confused when deciding. The problem of finding its equivalents comes to many people.
There is a higher demand for this type, so it’s sometimes out of stock. Some brand names are Energizer, Varta, Duracell, UltraFire, Panasonic, etc. It’s especially used a lot in film cameras and medical equipment.Īlso, it’s produced by many manufacturers thanks to its high demand in the market. This type of battery can be applied to various power devices, such as photographic equipment, flashlights, remotes, motion detectors, calculators, etc. We likely define it by the dimension of 27mm x 15.6mm. For easily illustrated, we can recognize it as a mini version of the D-cell battery. It is a lithium chemistry-based cylindrical battery.
