LR43 Battery Discharge Analysis

LR43 batteries exhibit specific discharge characteristics, which can vary based on several factors. When a load is applied, the discharge behavior can change, affecting the battery's overall performance. Additionally, temperature plays a crucial role, as it can influence the battery's ability to deliver power effectively. Understanding how these factors impact the discharge capacity of LR43 batteries is essential for maximizing their lifespan and performance in various applications.

■ Discharge Characteristics

At a load of 6.8kΩ and a temperature of 23°C, the LR43 battery exhibits stable discharge characteristics. It maintains a consistent voltage output suitable for powering low to moderate energy devices. However, for high-drain applications, it may experience a gradual voltage drop. Temperature has a minimal impact on its performance at this level, with the battery delivering reliable power output.

■ Discharge Characteristics on Load

The discharge characteristics of the LR43 battery vary depending on the load applied. At lower loads, the battery can maintain a relatively stable voltage output, making it suitable for devices with modest power requirements. However, as the load increases, the voltage output may decrease gradually. It's crucial to take into account the particular load needs of your gadget in order to guarantee the best possible performance and extended lifespan of the LR43 battery.

■ Discharge Characteristics by Temperature

The LR43 battery's discharge characteristics can be influenced by temperature. At lower temperatures, its capacity may decrease, leading to reduced runtime. Conversely, higher temperatures can increase the battery's self-discharge rate, affecting its overall lifespan. For the LR43 battery to continue performing at its best, it is crucial to use it within the recommended temperature range.

■ Discharge Load vs. Discharge Capacity

The discharge load and discharge capacity of the LR43 battery are interconnected factors that affect its performance. The discharge load, expressed in ohms, establishes the maximum current that a battery can supply to a gadget. Generally speaking, a larger load causes a faster rate of discharge and lower battery life. On the other hand, the discharge capacity of the LR43 battery, measured in milliampere-hours (mAh), indicates the total amount of energy it can deliver before becoming depleted.

When choosing an LR43 battery for a specific application, it's essential to consider both the discharge load and discharge capacity to ensure the battery can meet the device's power requirements. High-drain devices, such as digital cameras or flashlights, require a battery with a higher discharge capacity to provide sufficient power for an extended period. Conversely, low-drain devices, like remote controls or calculators, may operate efficiently with a battery that has a lower discharge capacity. Matching the battery's discharge characteristics to the device's power needs is key to optimizing performance and maximizing battery life.

LR43 Battery Equivalents

The LR43 battery is interchangeable with several other battery models, including the AG12, 186, 301, 386, and SR43W. While these batteries may have minor differences in dimensions and capacity, they are functionally equivalent and can be used interchangeably in most devices that accept LR43 batteries. Here is their detailed comparison table:

LR43 vs. CR1225

When comparing the LR43 and CR1225 batteries, one of the key distinctions lies in their voltage ratings. The LR43 operates at 1.5 volts, while the CR1225 is a 3-volt battery. This fundamental difference makes them incompatible for direct replacement in devices designed for one or the other.

With a 1.5-volt rating, the LR43 is a popular component found in many small electronic gadgets, including watches, calculators, and small toys. Its lower voltage output is suited for applications where higher voltages are not required, and its compact size makes it ideal for use in these types of devices.

On the other hand, the CR1225's 3-volt rating makes it suitable for devices that require higher voltage levels or where the LR43's lower voltage output would be insufficient. Devices such as key fobs, medical devices, and some small electronics use the CR1225 for its higher voltage and longer-lasting power.

The LR43 and CR1225 are not the same in terms of size. The LR43 is a cylindrical battery measuring approximately 11.6 mm in diameter and 4.2 mm in height, while the CR1225 is a coin cell battery with a diameter of about 12.5 mm and a thickness of around 2.5 mm. This size difference means that the two batteries are not interchangeable in devices that require a specific form factor.

While both the LR43 and CR1225 are small, button cell batteries commonly used in electronic devices, their differences in voltage and size make them suitable for different types of applications. To guarantee correct operation and performance, use the battery type that the device maker specifies.
