LR41 VS SR41 – What Is The Difference?

Batteries are an essential item in every household. The LR41 and SR41 batteries are two commonly used button cell batteries that can power various devices. While both batteries are of good quality, they differ in some ways. In this article, we’ll explore the differences between the LR41 and SR41 batteries, and which one to choose for your device.

LR41 Battery

The LR41 battery is an alkaline battery with a nominal voltage of 1.5v. It uses manganese dioxide as the cathode material, providing resistance to leakage, an excellent pulse discharge characteristic, and regular discharge output even under high drain conditions while maintaining electric voltage stability. The physical dimension of the LR41 battery is consistent across many manufacturers and types, with a cylindrical, disc-shaped cell that measures 7.9mm in height and 3.6mm in diameter. The capacity of the LR41 battery ranges from 25 mAh to 32 mAh for alkaline batteries, and it can be as high as 1.55V when brand new. The LR41 battery is commonly used in wristwatches, laser pointers, digital voice recorders, and clocks.

SR41 Battery

The SR41 battery is made from silver-oxide and has a nominal voltage of 1.55v, which is slightly higher than the LR41 battery. It has a high energy density, which contributes to its enhanced storage characteristics. The physical dimension of the SR41 button battery is consistent, with a diameter of 7.9mm and varying heights, some being taller than others at about 0.42 inches tall. The SR41 battery is commonly used in watches like Casio, calculators like Texas Instruments’ TI-30Xa, some laser points, kids’ toys, cameras, and more.

LR41 and SR41: Compatibility and Interchangeability

SR41 batteries can be used interchangeably with LR41 batteries. Both are quality button cell batteries that work just fine in any application. The LR41 and SR41 are both button batteries used for small electronic devices that need a very compressed power source. Both can be used on the same device without any issue. The difference between the SR41 and the LR41 isn’t significant for most applications.

Which Works Best, LR41 or SR41 Battery?

Both the LR41 and SR41 batteries are of good quality and can be used interchangeably for most applications. However, the silver oxide in SR41 batteries has larger capacities and can give a somewhat longer lasting time, making it a better option for devices with higher power drains that require more voltage.

Will These Batteries Work for a Vibrating Tongue Ring?

A vibrating tongue ring is not a common accessory, and different models may require different batteries. Some require AG3 batteries, while some local brands may use LR41 batteries. To avoid disappointment, check the specifications of the tongue ring from the manufacturer to know which battery type is required for this device.


LR41 and SR41 batteries are widely used in many different devices, including watches, calculators, and other small devices. They are convenient, reliable, and easy to find in most hardware stores and big-box retailers. These button batteries come in very small sizes and can fit in the smallest devices. They’re also very low cost, which makes them perfect for a number of different applications.

However, it’s important to handle these batteries with care since they contain chemicals that can be harmful if not handled properly. If ingested by children or pets, button battery ingestions should be considered an emergency because these tiny objects have the potential to quickly become lodged in the esophagus, where intense corrosive injury results from tissue reaction with lithium salts contained inside each cell. When this happens, it is critical for immediate medical attention, so be very cautious when handling these batteries, even in storing them with other objects. It is always recommendable to keep these batteries out of reach of little children.

Before purchasing any of both batteries, make sure that the brand is marked with zero percent hg. Zero percent means you will be safe if or whenever there is leakage.

If you’re unsure which brand to use in your device, pick a reputable battery model from one of the more well-known brands used by many people for different purposes.

Remember to always handle batteries with care and keep them away from children and pets. With this knowledge, you can now make an informed decision on which battery to choose for your device.
