Ⅱ. What does CR123 mean?

The International Electrotechnical Commission (IEC) determines the nomenclature of batteries and the rules are as follows:

• The prefix C indicates that the battery uses lithium chemistry, specifically LiMnO2 (lithium-ion manganese oxide).

• R represents the shape of the battery, which is round.

• The following numbers indicate the size of the battery, with 123 indicating that the battery is two-thirds the size of a standard battery.

Ⅲ. Characteristics of CR123A

1. Environmental protection: CR123A battery does not contain harmful substances such as mercury and lead, so it is environmentally friendly.

2. High energy density: Compared with alkaline dry batteries, CR123A batteries have higher energy density. It provides longer usage time to the device.

3. Its open circuit voltage recovers quickly after an instant short circuit. This means that the voltage will not drop instantly when the battery is short-circuited, but will quickly return to normal levels.

4. Long service life: Under normal conditions, CR123A batteries can be stored for more than 10 years.

5. Stable performance: CR123A battery has small voltage fluctuations and can provide stable power supply, thereby ensuring the normal operation of semiconductor equipment. Even under extreme low temperature conditions of -40°C, its performance can still reach 60% of the level at normal temperature.

6. It has good storage performance. Its storage period is more than 5 times that of ordinary dry batteries, and its operating temperature range is wide. It means that the battery can not only work stably in various environments, but also be stored for long periods of time without performance degradation. In addition, it has NTC and detonation functions inside, making it safer for people to use.

Ⅳ. Discharge temperature characteristics

Ⅴ. What is the difference between RCR123A and CR123A?

Difference one: Battery capacity

CR123A battery capacity is higher. The capacity of CR123A batteries is around 1300~1700, while the capacity of 16340 batteries is mostly around 700.

Difference two:

RCR123A is rechargeable, while CR123A is a non-rechargeable disposable battery.

Difference three: Place of use

The CR123A battery can be used for civilian use, and its stability is much higher than that of the RCR123A battery, specifically manifested in low temperature resistance, no leakage, and low self discharge electrode. This is also the core reason why SureFire flashlights have persisted in using CR123A batteries since their inception until now. At present, the RCR123A battery is still an industrial cell and only appears in some civilian equipment.

Difference four: Voltage

The open circuit voltage of the RCR123A battery when fully charged is 4.2V, while the open circuit voltage of the CR123A battery does not exceed 3.2V. Because of this, RCR123A batteries cannot replace CR123A batteries unless there is a compatible circuit. For example, flashlights are still in the era of light bulbs. If two RCR123A batteries are installed into the SureFire flashlight instead of two CR123A batteries, the lamp beads will burn out.

Ⅵ. Application of CR123A

CR123A batteries are widely used in various fields. For example, in a night vision device, this battery can provide enough power to the device to allow it to function normally in the absence of light and light. In addition, in fields such as LED flashlights and CD players, CR123A batteries can also provide stable and reliable power supply to ensure their normal operation. When it comes to lighting, CR123A batteries play a crucial role. This kind of battery has high energy density and can provide a long-lasting and stable energy source for lighting equipment. In addition, in digital cameras and security equipment such as electronic locks and electronic alarms, CR123A batteries are also favored for their high energy density and high reliability. In addition, the use of CR123A batteries in smoke detectors can provide the required power for the smoke detector so that it can quickly alarm when a fire occurs. These batteries have a large energy reserve, allowing the detector to operate at extremely low temperatures. In addition, CR123A batteries are also widely used in automobile electrical installation and medical equipment (such as AED). In these areas, the CR123A battery's high energy density, stability and reliability make it an ideal power source choice. CR123A batteries can be used in vehicle emergency call systems and medical instruments to provide stable and reliable power supply to ensure that they can still play their due role in critical moments.
