Swing by contradicting opinions about CR123 vs. CR123A? It is a confusing matter. There is no major comparison between CR123 and CR123A batteries. Both are similar except for the letter ‘A’. CR123A is the main level from the CR123, 123, 123A, DL123A, or other.
However, if you want to learn about in-depth explanations of the CR123A batteries, you arrive at the right place.
Perhaps, you have any questions in mind about CR123 vs CR123A. Our article is written by including all informed answers along with a lot of information about CR123A batteries.
Definition of CR123 Vs. CR123A Batteries
CR123 and CR123A batteries have no difference and they are the same size. Their features and specifications are also equal. But, the main difference between CR123 and CR123A is the names just including A.
CR123A or CR123 batteries are very prominent & the high-performance 3V cylindrical lithium batteries arrive in two leading versions like rechargeable and non-rechargeable batteries. These batteries are acceptable for cameras, photos, flashlights, military equipment, security devices, and more.
CR123 Is CR123A And CR123A Is CR123
Yes, CR123, CR123A, 123, 123A, DL123A, and ELD123A are the same thing and have similar features. Just known as different levels or names used by multiple manufacturers. For example, Energizer 123, Rayovac 123A, Duracell CR123, Panasonic CR123A, etc. So, the main difference between CR123 and CR123A is the letter “A”.
But remember, the main label is ‘CR123A batteries’ that indicate the non-rechargeable type, or ‘RCR123A batteries’ which indicate the rechargeable type. Other common labels are
CR17345, K123A, SF123A, RCR 16340, 16340, VL123A, DL123A, 5018LC, EL123AP, 17345, 17340, etc. Don’t forget that they all are also labeled as ‘CR123A’.
CR123A Batteries: Features and Specifications
The basic dimensions of the CR123A batteries are 0.67-inch x 1.36 inch, 17 mm diameter, and 34.5 mm in height of these kinds of batteries.
According to the CR123A battery models & chemistry, they have several voltages, nominal capacity, and drain current. The following specifications can provide you with an exact idea.
|Voltage||3 Volts or 3.6-3.7 Volts|
|Terminal||Nub end (positive) and flat end (negative)|
|Capacity||1,500 (non-rechargeable) and 700 (rechargeable) mAh|
So, the non-rechargeable battery nominal voltage is 3.0 volts and has a typical capacity of 1500 mAh. From 7 to 10 years is the shelf life range. Due to its high drain current, it is an excellent choice for high-power devices and standby mechanisms like security devices.
Rechargeable CR123A batteries mean RCR123A batteries usually contain voltage from 3.6 to 3.7. Remember, 3.0 and 3.3 volts rechargeable batteries are also accessible in the market. The nominal capacity is in the 500 to 800 mAh range.
CR123A Vs. RCR123A Batteries
There are many differences between CR123A and RCR123A batteries. The major differences are their output voltage, capacity, charging or discharging cycles, and more. Here is a comparison table to focus on details.
|Definition||CR123A Batteries||RCR123A Batteries|
|Nominal Voltage||The output voltage is around 3.0 volts, lower than RCR123A batteries.||These batteries have an output voltage of usually 3.6 to 3.7 volts so higher than non-rechargeable.|
|Capacity||CR123A batteries have a capacity of ~1500 mAh.||RCR123A batteries have a nominal capacity of 500-800 mAh and some models feature around 700-750 mAh capacity.|
|Shelf life & storage||The shelf life of CR123A batteries is up to 10 years. They are only half-charged when manufactured. So, you have to charge them fully before using them fast.||These RCR123A batteries come with less than 10 years of shelf life. But, they are transported fully charged.|
|Charging/discharging cycles||A best CR123A battery is discharged only once when it needs to be replaced and includes a new one.||RCR123A batteries have 1000-1200 charging or discharging cycles. When you use the proper charger, you can utilize these batteries until they die.|
|Safety Feature||A good CR123A battery feature protect high temperature or fire, over-voltage,short circuit, and similar.||RCR123A batteries are also safe from short circuits, overheating, surge currents, over-voltage, and more.|
CR123A vs 18650
There is no brightness difference between the CR123A rechargeable battery and the lithium 3.6 volts 18650 rechargeable battery. But, the basic difference between CR123A and 18650 Batteries is the size. The CR123A battery’s diameter is 17 mm, whereas 18650 batteries are 18.6 mm in diameter. A good CR123A battery’s height is half of the lithium 3.6 volts 18650 battery’s height, 65.2 mm.
Another thing, you know, the running time depends on the milliamp-hour (mAh)ratings of any individual battery. Maximum CR123A batteries are measured for probably 1000 mAh. On the other hand, 18650 rechargeable rates vary whether 2600 mAh or 3400 mAh.
The large mAh indicates the more energy of the battery and longer run times. The 18650 battery features 3.7 volts that are higher than the CR123A rechargeable and non-rechargeable batteries.
So, we can say, two CR123A batteries’ energy is equal to one 18650 battery. There is no doubt that the rechargeable 18650 batteries last longer than the CR123A batteries.
Luckily, some renowned devices are formed using either one 18650 battery or two CR123A batteries. So, the calculation is very simple.
2x CR123A = 1x 18650 battery
Although there is a 3 to 4 mm difference
Another difference is CR123 batteries are typically more reasonable than rechargeable 18650 batteries. But, don’t skip, the two CR123A equals one 18650 rechargeable.
