What Size is a LR41 Battery?
Have you ever come across a device or gadget that requires an LR41 battery and found yourself wondering what size it is? LR41 batteries are small, round, button cell batteries that are commonly used in various electronic devices. In this article, we will delve into the size and dimensions of LR41 batteries, as well as provide you with an in-depth understanding of their applications, compatibility, and other useful information. So, let’s get started!
Understanding LR41 Batteries
LR41 batteries, also known as AG3, LR736, and 392 batteries, are miniature alkaline button cells. These batteries are part of the LR (alkaline) series and are designed to provide a stable and reliable power source for small electronic devices. The LR41 battery is cylindrical in shape with a diameter of about 7.9 millimeters (mm) and a height of approximately 3.6 mm.
Dimensions and Size Variations
The size of LR41 batteries is relatively consistent across different manufacturers. However, variations may exist in terms of height and weight. Here are some common dimensions and size variations you may come across when purchasing LR41 batteries:
- Diameter: 7.9 mm
- Height: 3.6 mm (may vary slightly)
- Weight: Approximately 0.6 grams (may vary slightly)
It’s important to note that LR41 batteries are standardized to provide compatibility with devices that require this specific size. However, due to the compact size of these batteries, it’s always a good idea to check the device’s specifications or consult the manufacturer to ensure perfect fitment.
Comparison with Other Button Cell Batteries
While LR41 batteries have unique dimensions, it’s helpful to compare them with other common button cell batteries to get a better understanding of their size:
- LR44 (AG13, A76) Battery: This battery has a similar diameter to the LR41 at 11.6 mm, but it is taller, measuring 5.4 mm in height.
- CR2032 Battery: The CR2032 is larger than the LR41, with a diameter of 20 mm and a height of 3.2 mm. It is commonly used in watches, calculators, and other small electronic devices.
- LR626 (AG4, 377) Battery: Slightly smaller in diameter than the LR41, with a size of 6.8 mm, the LR626 battery is taller at 2.6 mm.
These comparisons can help you differentiate between various button cell batteries and identify the correct size you need for your device.
Common Applications
Now that we understand the size and dimensions of LR41 batteries, let’s explore some of the common applications where you might come across these compact power sources:
