What are the main differences between LR44 and SR44 batteries?
Main Differences Between LR44 and SR44 Batteries
While the LR44 and SR44 batteries may appear similar in size and shape, they have significant differences that affect their performance and applications. Here are the key distinctions:
1. Chemical Composition
- LR44: This battery is an alkaline battery, composed of zinc and manganese dioxide. It is known for being cost-effective and widely available, making it suitable for general use in low-drain devices[1][2].
- SR44: In contrast, the SR44 is a silver oxide battery, utilizing silver oxide as the positive electrode and zinc as the negative electrode. This composition provides higher energy density and stability, making it ideal for precision devices[1][2][3].
2. Voltage Output
- LR44: The nominal voltage of an LR44 battery is 1.5 volts, but this voltage decreases gradually as the battery discharges, which can impact the performance of devices requiring consistent power[2][4].
- SR44: The SR44 maintains a slightly higher nominal voltage of 1.55 volts throughout most of its life cycle, providing more stable power output essential for sensitive electronic devices[1][3][4].
3. Capacity and Lifespan
- LR44: Typically has a capacity ranging from 110 to 130 mAh. This battery is designed for general applications but tends to have a shorter lifespan, especially in high-drain devices due to quicker discharge rates[2][3].
- SR44: Offers a higher capacity of around 150 to 200 mAh, allowing it to last longer under similar conditions. Its slow self-discharge rate makes it suitable for devices that require prolonged power without frequent replacements[1][2].
4. Performance Characteristics
- LR44: Alkaline batteries like the LR44 are effective for low-power applications but may not perform well in devices that need a steady voltage supply over time[1][3].
- SR44: The silver oxide chemistry provides consistent performance, making SR44 batteries preferable for high-drain and precision applications such as watches, cameras, and medical devices[2][3].
5. Cost
- LR44: Generally less expensive due to its simpler composition and widespread availability[2].
- SR44: More costly because of the materials used in its manufacture and its superior performance characteristics, which justify the price difference for critical applications.

Here are the answers to your questions:
1. Which battery is equivalent to LR44?
Several batteries are equivalent or similar to the LR44. Some common equivalents include:
- AG13
- LR1154
- A76
- 303
- V13GA These batteries typically have the same size and voltage (1.5V), but may differ in their chemistry or specific characteristics, like lifespan or temperature tolerance.
2. Is an LR44 battery the same as a 357?
No, an LR44 is not the same as a 357 battery. While they are very similar in size and both deliver 1.5V, the 357 is a silver oxide battery, whereas the LR44 is an alkaline battery. Silver oxide batteries, like the 357, tend to have a more stable voltage output and longer lifespan compared to alkaline batteries. However, they are not interchangeable in every device, as some devices are specifically designed for one type over the other.
3. Is LR44 battery the same as 1.5V?
Yes, the LR44 battery provides 1.5V of power, which is the standard voltage for alkaline button cell batteries. Other types of batteries may be similar in size but can provide different voltages, so it’s important to check the specifications for compatibility.
4. Is LR44 battery the same as CR2032?
No, the LR44 is not the same as the CR2032. Although both are small button cells, they have different sizes, chemistries, and voltages:
- LR44 is an alkaline battery with a voltage of 1.5V.
- CR2032 is a lithium battery with a voltage of 3V. These differences make them incompatible for most devices. Always check the specifications of your device to ensure the correct battery type.
Conclusion
When choosing between LR44 and SR44 batteries, consider the specific requirements of your device. For general use in low-drain applications, LR44 may suffice; however, for precision instruments requiring stable voltage and longer life, SR44 is the better option.
The LR44 battery has several equivalents that can be utilized depending on the specific needs of your device. Understanding these alternatives allows for easy replacement while ensuring continued functionality of electronic devices. When selecting a replacement, consider both the chemistry and specifications to ensure optimal performance.
