Do lithium 123a batteries self - discharge?

Leave a message

Lithium 123A batteries have become an essential power source in various applications, from photography equipment to home security systems. As a leading supplier of lithium 123A batteries, we often receive questions from our customers about the self - discharge characteristics of these batteries. In this blog, we will explore whether lithium 123A batteries self - discharge, the factors influencing self - discharge, and how it impacts their performance.

What is Self - Discharge?

Self - discharge is a natural phenomenon that occurs in all types of batteries. It refers to the loss of battery charge over time when the battery is not in use. Essentially, even when a battery is sitting idle on a shelf, it is slowly losing its energy. This is due to internal chemical reactions within the battery that continue to take place, consuming the stored energy.

Do Lithium 123A Batteries Self - Discharge?

The short answer is yes, lithium 123A batteries do self - discharge, but at a much lower rate compared to other battery chemistries. Lithium - based batteries, such as the 123A type, are known for their relatively low self - discharge rates. Typically, lithium 123A batteries self - discharge at a rate of about 1 - 3% per month at normal temperatures (around 20 - 25°C).

This low self - discharge rate is one of the key advantages of lithium 123A batteries. For applications where batteries need to be stored for long periods without losing a significant amount of charge, lithium 123A batteries are an excellent choice. For example, in emergency backup devices like smoke detectors or flashlights, you can rely on lithium 123A batteries to retain their charge for a long time, ensuring that the device is ready for use when needed.

Factors Influencing Self - Discharge

Several factors can influence the self - discharge rate of lithium 123A batteries:

Temperature

Temperature has a significant impact on the self - discharge rate of lithium 123A batteries. As the temperature increases, the self - discharge rate also increases. At higher temperatures, the chemical reactions within the battery speed up, leading to a faster loss of charge. For instance, if a lithium 123A battery is stored at 40°C, its self - discharge rate can be as high as 5 - 7% per month. On the other hand, storing the battery at lower temperatures can slow down the self - discharge process. However, extremely low temperatures can also affect the battery's performance in other ways, such as reducing its capacity and increasing its internal resistance.

State of Charge

The state of charge (SOC) of the battery when it is stored also affects the self - discharge rate. Batteries that are stored at a full charge tend to self - discharge at a slightly higher rate than those stored at a partial charge. This is because when a battery is fully charged, the internal chemical reactions are more likely to occur, leading to a faster loss of energy. Therefore, if you plan to store lithium 123A batteries for an extended period, it is recommended to store them at around 40 - 60% of their full charge.

Battery Age

As lithium 123A batteries age, their self - discharge rate may increase. Over time, the internal components of the battery can degrade, which can lead to more significant self - discharge. This is why it is important to check the age of the batteries when purchasing them and to use older batteries first.

Impact of Self - Discharge on Performance

The self - discharge of lithium 123A batteries can have several impacts on their performance:

Shelf Life

The low self - discharge rate of lithium 123A batteries contributes to their long shelf life. This means that you can store these batteries for several years without significant loss of charge. For businesses that need to stockpile batteries for future use or for consumers who want to keep a supply of batteries on hand, the long shelf life of lithium 123A batteries is a major advantage.

Readiness for Use

Since lithium 123A batteries self - discharge at a low rate, they are more likely to be ready for use when needed. For example, in a camera that uses lithium 123A batteries, you can leave the batteries in the camera for an extended period without worrying about them losing too much charge. When you are ready to take a picture, the batteries will likely still have enough power to operate the camera.

Performance Consistency

The low self - discharge rate also ensures more consistent performance over time. Batteries with a high self - discharge rate may experience a significant drop in voltage during storage, which can affect the performance of the device they are powering. With lithium 123A batteries, the voltage remains relatively stable over long periods of storage, providing more reliable power to the device.

Comparison with Other Battery Types

When comparing lithium 123A batteries with other battery types, the difference in self - discharge rates becomes even more apparent.

  • Alkaline Batteries: Alkaline batteries have a relatively high self - discharge rate, typically around 20% per year. This means that over time, alkaline batteries will lose a significant amount of their charge even when not in use. In contrast, lithium 123A batteries will retain most of their charge over the same period.
  • Nickel - Metal Hydride (NiMH) Batteries: NiMH batteries also self - discharge at a higher rate than lithium 123A batteries. NiMH batteries can self - discharge at a rate of about 15 - 20% per month when stored at normal temperatures. This high self - discharge rate makes them less suitable for long - term storage applications.
