![]() I have found the most common designator for these batteries is CR123A. They are all lithium chemistry batteries with a nominal voltage of around 3.0 volts and a capacity ranging around 1000-1500 mAh. These batteries are all interchangeable, and there is no operational difference between them. Rechargeables have about half as much power as a primary, but are rechargeable.ġ-4 of 4 Answers No, these batteries are not equivalent to CR-123.ĭon’t worry. They make similarly sized rechargeable cells usually called RCR123. The CR2 battery is slightly shorter than the CR123A battery and will not fit in most applications that require a CR123A battery.ġ8650 is a bit thicker and about as long as 2 CR123s, with higher voltage. Correct? “CR” is the chemical symbol for chromium, is chromium somehow used in making a 123A battery? Do they still make “A” size batteries?Īre CR2 Batteries The Same As CR123A? The CR2 battery is not the same as the CR123A battery. If I understand, the 123A designates the battery as one battery that is 2/3rds the size of an “A” size battery. Choosing a CR123A for these applications has many advantages. Initially designed for use in cameras, CR123A batteries are now widely used in Wireless Security, Home Automation, Smoke Detectors, Illumination Equipment, Tactical Equipment and more. The CR123A battery size is known as a “camera battery”. On average, a CR123A lithium battery will offer a lifespan of three (3) to five (5) years. The first two numbers let you know the diameter of the battery and the last two numbers tell you the height. The R lets you know that the battery is round in shape. The C in CR lets you know the battery uses a lithium chemistry. When you compare their functionality, performance, lifespan and chemistry, the two are essentially one and the same thing. Additionally, There are many different part numbers for the battery, with each manufacturer using a slight variant of the main part number.Įnergizer Lithium 123 Battery, Replaces All CR123A Batteries.Īre CR123 and CR123A batteries the Same? It’s safe to say the only major difference between the two is the letter A. Cr123a is a lithium ion battery while duracell 123 is an alkaline battery. No, cr123a and duracell 123 are not the same. One CRP2 cell can be used to replace two Duracell 123 batteries. The CRP2 battery has similar dimensions to CR123A Duracell batteries with a height of 36 mm, length of 35 mm and 19.5 mm diameter. What is the equivalent of a CR123A battery?ĬRP2 batteries can be used to replace CR123A batteries in specific devices. For this reason, each of the batteries, and more specifically the CR123 and the CR123a are 100% interchangeable. For this particular sized battery, the ‘a’ makes no difference. If you such for 123 lithium batteries, you will often find a selection of CR123s or DL 123As. In actual fact, in the case of these batteries, there is no difference. The LED may require a voltage of about 3.5V or less depending on how hard it is being driven but the actual number will vary with the type of emitter. Originally developed for use in digital cameras, the CR123 has become a popular choice for powerful LED flashlights because of its relatively high voltage (3V) and its minimal weight.Ī driver designed for two CR123 cells won’t necessarily be dimmer on 1 18650 as they still are able to deliver a voltage suitable for driving the LED. What does “CR123A” mean? CR123 – A CR123, also known as a CR123A is a compact, primary battery. ![]() ![]() ![]() Generally, these are not rechargeable batteries. ![]() What Is the Difference Between A CR123 And A CR123A Battery? Except for different brands using various designations, there is no difference among them. ![]()
