LR41 VS SR41 – What Is The Difference?

You may have thought, lr41 battery size? The main difference between LR41 and SR41 batteries is that the LR41 has a nominal voltage of 1.5v, while the SR41’s nominal voltage is slightly higher at 1.55v. Also the LR41 is an alkaline battery while the SR41 is made from silver-oxide.

Batteries are a product that every household needs. These batteries, such as the LR41 and SR41, can be used to power your devices, depending on their specifications. The quality of these two types is comparable but different in certain ways, which makes it helpful for you to know more about them before choosing one or both.

Generally, the SR41 battery can be used interchangeably with LR41 batteries. It’s important to note that both types are quality button cell batteries, and they should 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.

To better give you an idea of the difference between LR41 and SR41 batteries, we’ll discuss each in detail below.

LR41 Battery

Best Features: LR41 batteries provide a cost-effective and stable performance. This is because of their use of manganese dioxide as the cathode material, which provides resistance to leakage, an excellent pulse discharge characteristic, regular discharge output even under high drain conditions while maintaining electric voltage stability.

Physical Dimension: The lr41 battery size is consistent across many manufacturers and types. The LR41 battery is a cylindrical, disc-shaped cell. Both the height and diameter of the cells are 7.9mm and 3.6mm, respectively, in measurements.

Capacity and Voltage: The voltage of the LR41 is 1.5V, but if it’s brand new, it can be as high as 1.55V because that depends on its capacity ranging from 25 mAh to 32 mAh for alkaline batteries and reliant on how much power a device draws before shutting off (1.2v or 0.9 v).

Uses: The LR41 is used in a variety of small devices with little power needs. These include wristwatches, laser pointers, digital voice recorders, and clocks.

SR41 Battery

Best Features: The SR41 battery has a high energy density, which contributes to the enhanced storage characteristics. SR41 battery voltage maintains constant output during discharging and resists leakage well.

Physical Dimension: SR41 button batteries are all the same size, and have a consistent diameter of 0.311inch and 7.9mm. They also vary in height, with some being taller than others at about 0.42 inches tall (3.6mm).

Uses: The SR41 is a silver oxide battery model that lasts longer than most of its counterparts and can be used for small electronic devices. The popular application and device the SR41 works well with watches like Casio, Calculators like Texas Instruments’ TI-30Xa, some laser points, kids’ toys, cameras, and more.

The LR41 cells are alkaline, but they are comparable enough to most silver oxide versions that the difference is minor. The difference between the SR41 and the LR41 isn’t huge for most applications.

Which works best, LR41 or SR41 battery?

Regardless, for individuals who just want a little more voltage, the silver oxide is your best bet because it has larger capacities and can give a somewhat longer lasting time. In addition, silver oxides are more appropriate for an electric device with higher power drains.

Will these batteries work for a vibrating tongue ring?

A vibrating tongue ring is not a very common type of accessory. It’s difficult to say for sure without knowing the specs on the tongue ring. Some require AG3 batteries for this device to work. To some local brands may use LR41 batteries to power this accessory. To avoid disappointment, check the specifications of the tongue ring from the manufacturer. This way, you will know which battery type is required for this device.


SR41 and LR41 batteries are very popular and widely used in many different devices. These button cell batteries work perfectly in watches, calculators, and other small devices. They are convenient and 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.

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. Before opting to purchase 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.

It’s important to handle these batteries with care since they contain chemicals that can be harmful if not handled properly. If swallowed, these button batteries can cause serious internal burns that could lead to bleeding within 2 hours of ingestion.

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. No one likes accidents and injuries, so if you have young kids at home, it’s best to always keep your batteries in proper storage. It is always recommendable to keep these batteries out of reach of little children.
