It is quite common in products such as children's toys, adult watches, and high-precision calculators. However, this kind of button battery, which is very common in daily life, has a series of complex scientific and engineering problems hidden behind it.
The volume design of the LR44 battery allows it to easily fit into a variety of size-restricted devices. Its specific dimensions are 11.6 mm in diameter and 5.4 mm in height. LR44 batteries generally operate at a voltage of 1.5 volts. This value does not come out of thin air but is determined as the optimal operating voltage after multiple rounds of careful calculations and experimental data verification.
Similar to many battery types, LR44 also has an optimal operating temperature range, usually around 20°C. The selection of this value is not random or arbitrary but is based on electrochemical and materials science principles. In this temperature environment, chemical reactions within the battery reach a certain steady state, which helps maximize electrical energy output and extend service life.
The reliability and versatility of LR44 batteries make them useful in many ways. Taking the medical field as an example, the battery is used to power portable hearing aids and blood glucose measuring instruments.

Solving this problem requires developers to adopt more complex chemical composition and structural strategies during the battery design stage to adapt to various temperature changes.
Figure 2: LR44 Battery
The reason why LR44 batteries can be commonly used in different scenarios in daily life is that every aspect of it, whether it is size design, working voltage selection, or temperature adaptability, has been rigorously planned and tested to adapt to a variety of different situations. Practical application requirements.
In-Depth Analysis of Technical Specifications: Performance and Environmental Factors of LR44 Battery
The LR44 battery is not just a simple energy storage device, it is actually a highly complex integrated system that covers many aspects of engineering, material science, and even environmental adaptability. These different data indicators are not isolated individuals, but coexist in an intertwined and mutually influencing network, shaping the comprehensive performance of the battery in various application environments.
Taking the average working capacity of 120mAh as a starting point, this indicator undoubtedly outlines a clear boundary for the battery's application range. Take medical equipment as an example, especially those portable electrocardiographs. They not only need to work continuously for a long time but also require the accuracy and stability of the current output. In this situation, LR44 batteries naturally become the first choice due to their robust working capacity.
Figure 3: LR44 Battery
The structure of the flat contact end, this seemingly unimportant detail, actually has a significance that cannot be ignored in terms of the stability and reliability of the current transmission. Taking modern smart headphones as a scenario, this design allows the battery to provide a continuous and efficient power supply even in an extremely small physical space.
Speaking of rated capacity, especially at a temperature of 23°C and a resistance of 4.7k ohms, this indicator is more like a dynamic balance result, reflecting how battery performance is restricted by the external environment. For example, when the temperature fluctuates up and down, the speed of internal chemical reactions is likely to change, which indirectly affects the battery's working capacity and expected service life. Similarly, when the resistance changes, the current output will be affected accordingly. This phenomenon is especially obvious when electronic equipment is used at high altitudes or in cold environments.
In this way, we have a deeper understanding of the multi-faceted technical specifications and environmental adaptability of LR44 batteries. From operating capacity to contact design to environmental considerations, these seemingly disparate details are a synthesis of engineering and materials science wisdom, brought together under a common goal: to build a high-performance, adaptable battery.
Characteristics and Voltage: Microscopic Exploration of Multiple Performance Indicators
Considering the multi-dimensional characteristics of LR44 battery performance, it actually involves a series of delicate and complex voltage and characteristic parameters. Its open circuit voltage (Open Circuit Voltage, OCV) is maintained at a relatively stable 1.50 volts under a standard environment, but it is worth noting that when the external conditions approach extremes, such as the temperature plummeting to -10°C, and the load reaches 200 ohms/5 seconds, its closed circuit voltage (Closed Circuit Voltage, CCV) may drop sharply to 1.10 volts.
Figure 4: LR44 Battery
This voltage fluctuation cannot be underestimated in practical applications. Take outdoor adventure equipment as a scenario, which may include components such as navigation systems or emergency lights. These devices have a high probability of use in low-temperature environments. When this voltage drop occurs, the device may face certain performance limitations, but the point is that since the battery stabilizes at around 1.10 volts, basic functionality is maintained.
Then, the nominal voltage of this battery is 1.5 volts, but it should be emphasized that its cut-off voltage—the voltage at which the battery energy is almost exhausted—is generally in the range of 0.9 to 1.0 volts. Fluctuations in this voltage range naturally lead to discussions about the suitability of batteries for a wide variety of devices. Consider the scenario of digital cameras. Many modern models trigger an automatic shutdown mechanism after the battery voltage drops to a certain level to ensure the safety of the internal circuitry. Therefore, a thorough understanding of a battery's cutoff voltage becomes particularly important during the battery selection process.
By conducting a precise analysis of the multi-dimensional voltage and characteristic parameters of the LR44 battery, it is possible for us to more accurately evaluate the performance of this battery in various application scenarios. From the stability of open-circuit voltage to the fluctuation of closed-circuit voltage in extreme environments, and even the impact of cut-off voltage on device compatibility, all these factors form a panoramic picture of battery performance and application range. They not only reflect the maturity of battery technology but also provide us with a key decision-making basis in the battery selection process.
