The LR41 coin cell battery has a nominal voltage of 1.55 volts and a dimension of 3.6 mm x 7.9 mm. If you require an LR41 battery replacement and it is unavailable, there are other alternatives available on the market.


What is the LR41 battery equivalent? There are a plethora of battery replacements available nowadays if you're seeking for an LR41 replacement. Batteries  that are nearly the same size and specifications. These batteries are thought to be interchangeable with the LR41 button-type battery.


Ⅱ What is an LR41 Battery?

The LR41 Battery  is a tiny, alkaline button cell battery. The LR41 is a relatively common battery that is manufactured by many prominent brands including Toshiba, Maxell, and others. The LR41 battery is also extensively manufactured by smaller corporations and private label battery manufacturers, such as Tianqiu. Other firms, like as Energizer, make batteries that are identical in size to the LR41 but have a different composition, such as silver oxide.


Ⅲ Applications of LR41 Battery

LR41 batteries are widely utilized in a wide range of applications. They are only used in compact, portable electronic devices with low power consumption. Clocks, watches, laser pointers, thermometers, glucometers, voice recorders, heart rate monitors, cholesterol testing, and toys are examples of these gadgets.


These are only a few  of the most frequent devices for which an LR41 battery is used. It will take us a day to list all of them if we list them all. Typically, devices will indicate on the user's manual that they are powered by such a battery, and checking it is one way to ensure that the LR41 battery is suitable for the device.

Capacity and Voltage of LR41 Battery

When it comes to selecting the correct battery for an application, the capacity and voltage rating are the two most important specifications to consider. This is because the voltage rating of the battery will tell you how powerful the cell is and its electrical potential.


The capacity of the battery, on the other hand, will offer you an estimate of how long the battery will be able to power gadgets. Battery capacity also indicates how much current a cell can deliver over a given time span.


The LR41 coin cell battery is designed with a nominal voltage of 1.5 volts. If the battery is brand new, the voltage rating can rise to between 1.55 and 1.62 volts. Its capacity is normally in the range of 25 mAh to 32 mAh.


This is the packaging for ordinary alkaline batteries. The capacity of silver oxide LR41 cells, on the other hand, ranges between 38 and 45 mAh.


LR41 Battery Chemistry

The alkaline power cell chemistry is used in LR41 batteries. They are, nevertheless, designed to be almost identical to silver oxide coin-type batteries, making them interchangeable with their silver oxide equivalents.


When it comes to many applications, the difference between alkaline and silver oxide cells is negligible; nonetheless, silver oxide cells have a higher capacity, making them more appealing.


Helpful Hint: When purchasing LR41 power cells, check for those that have a "zero percent Hg" label. This signifies that the battery is free of mercury, which makes it safer if the battery leaks.


How to Install LR41 Batteries in Your Devices

Determine the positive and negative ends of the battery first. The flat side (sometimes with markings) of a common Alkaline LR41 battery is normally the positive side. A little round protrusion should be evident on the opposite side. Typically, the side is the negative end. You can easily align the positive and negative ends of the battery with the relevant markings on your device now that you've determined the positive and negative ends of the battery. Please keep in mind that certain gadgets feature small metallic tabs to help with battery retention and function. It is critical that these tabs remain unharmed and undamaged, as doing so may jeopardize the performance of your device. If you happen to move this tab slightly out of place, you can generally fix it by gently readjusting it back into the proper alignment.


What is the Equivalent to an LR41 Battery?

If the LR41 battery is unavailable, the AG3 coin cell battery is the best alternative. It is regarded as the best power cell comparable to the LR41 button-type battery. There are more LR41 replacements available, and they are all interchangeable with the button-type battery.


Some of the alternatives include CX42 cells, LR736, V3GA, V36A, GP192, G3, 92A, 384, 192, 392A, 392, SR41SW, SR41, and L736F. All of these power cells are considered equivalent cells of the LR41 coin cell battery,  and their specifications are nearly identical, allowing them to be interchanged.


So, if you need a replacement battery for a dead LR41 but can't find one, try for the batteries listed above. This will keep your device operational and allow you to get it back up and running quickly.


8.1 Alkaline

The alkaline alternatives are the most similar to the LR41 in terms of specifications, with the same voltage, mAh, and chemistry. One significant advantage of alkaline technology is its low cost, with this sort of battery costing only a few dollars.


When looking for equivalent batteries, keep the following in mind:










8.2 Silver-Oxide

A silver-oxide LR41 battery is quite similar to a conventional alkaline battery. The voltage is often 1.55 V, which is only slightly higher, but the capacity is generally increased. Whereas alkaline LR41s typically provide between 25 and 45 mAh, silver-oxide versions often provide 38 – 45 mAh.


The fact that silver-oxide chemistry retains a steady voltage output as it degrades is a huge advantage. This is important in applications that rely on the voltage of the battery, such as wristwatches and digital thermometers. Silver-oxide batteries will also outlast alkaline batteries.


Modern silver-oxide batteries are often multi-drain capable. SR41 style batteries were either low-current or high-current in the past, and it was critical to select the correct one for your device. Multi-drain batteries can produce both low and high currents.


When looking for silver-oxide LR41 counterparts, keep the following battery types in mind:









V392 (547)



The 3 Most Common Silver Oxide Equivalent of LR41

As previously stated, the LR41 button-type battery has numerous alternatives. Silver oxide counterparts, on the other hand, are preferred due to the additional capacity they provide. Here is a list of the top three LR41 silver oxide alternatives to learn more about.


These are your best options for a coin-type battery that has a higher capacity than the LR41.


1. The SR41W Button-Type Power Cell

The SR41W coin-type battery is a good silver oxide battery equal to the LR41. This battery is the same size as the previous one, measuring 7.9 mm × 3.6 mm and weighing 0.67 grams. It operates at temperatures ranging from -10 degrees Celsius to 60 degrees Celsius. The SR41W battery is designed with a nominal voltage rating of 1.55 volts and a nominal battery capacity of approximately 45 mAh.


As you can see, this coin-type battery has a higher capacity than the LR41, which means it will last longer. It can power devices for a longer period of time because to its ability to store more energy.


2. The 384 Button-Type Power Cell

Another excellent silver oxide option for the LR41 cell is the 384 button-type battery. It has a 7.9 mm diameter and a 3.6 mm height as well, but it is often heavier, weighing 1.14 grams.


This battery has the same nominal voltage and capacity rating as the first one, with 1.55 volts and 45 mAh, respectively. This LR41 silver oxide alternative is supposed to have a three-year lifespan, making it a more appealing option.


3. The 392 Button-Type Power Cell

The 392 coin-type battery is my third pick for the best silver oxide LR41 battery alternative. This battery weighs 0.32 oz and has the same measurements of 7.9 mm x 3.6 mm. It also has a nominal voltage rating of 1.55 volts and a battery capacity value of 45 mAh.


If the LR41 is not available, this is another excellent option due to its capacity to store more power and last longer.


Furthermore, the LR code indicates the type of chemistry employed inside the battery, which is lithium in this case.


Obviously, a battery that is equivalent to the LR41 must be of comparable size and voltage, but what about the chemistry and mAh ratings? Let's have a look at the chemistry-based options.

Ⅸ LR41 VS. SR41

The SR41 and LR41 batteries are small button/coin cell batteries that are commonly found in digital thermometers, wrist watches, toys, small LED flashlights, wearable electronics, remote controls, and other similar devices.


These batteries are available on the market in a variety of chemistries, with comparable but not identical discharge characteristics, and are frequently labeled differently by their makers, leading to some user confusion.


The physical dimensions of the SR41 and LR41 batteries are (D x H) 7.9 x 3.6 mm (0.311 × 0.142 inches), and their common properties are listed in the comparison chart below:


Chemistry Alkaline Silver-Oxide Zinc Air
Nominal Voltage 1.5V 1.55V 1.4 - 1.45V
Cutoff Voltage 1.0V 1.2V 1.1V
Notes Voltage drops over time Very constant voltage Slightly lower voltage, large capacity;
mostly used as hearing aid batteries
Typical Labels LR41, LR736, AG3 SR41, SR736, SR736PW, SR736SW, SG3, AG3, 192, 384, 392 312, ZA312, Brown Tab, PR41, 7002ZD
Typical Capacity 25-32 (45) mAh 38-45 mAh ~180 mAh


The real capacity of these batteries is determined by the device's cutoff voltage, but it is also determined by the drain current - the higher the current, the lower the final capacity.


Alkaline 7.9 x 3.6 mm batteries: The most frequent label for an alkaline 7.9 x 3.6 mm battery is LR41, however other labels, such as LR736AG3, and similar, are also used.


Fortunately, most respectable brands always include LR41 on the battery label, allowing users to quickly identify the battery type and model.


The LR41 battery has a nominal voltage of 1.5 volts and a capacity of 25-32 mAh. Some brands advertise significantly higher capacities for their LR41 batteries, but these batteries are frequently exhausted using ultra-low currents, with actual capacities commonly falling within the 25-32 mAh range.


The cutoff voltage of the LR41 battery is determined on the cutoff voltage of the device being powered, however it is often around 1.0 volts, while many basic devices can operate at 0.8 volts per battery.


Note: LR41 batteries are widely used, for example, as digital thermometer batteries. If the thermometer displays 'LO' or 'LOW,' it signifies that the measured temperature is below a specified threshold, not that the battery is (nearly) dead - always check the thermometer's instructions for confirmation!


The shelf life of LR41 batteries varies depending on storage temperature and manufacturer, however if the batteries are stored at or below 68-77°F (20-25°C), the estimated shelf life is at least 2-3 years.


Silver-oxide 7.9 x 3.6 mm batteries: The SR41 battery is the most frequent label for silver-oxide 7.9 x 3.6 mm batteries, while other labels such as SR736, SR736PW, SR736SW, SG3, AG3, 192, 384, 392, and similar are also used.


The nominal voltage of the SR41 battery is 1.55 volts,  and the nominal capacity is 38-45 mAh.


Silver-oxide batteries provide a more steady output voltage than alkaline batteries, making them a better alternative for powering more sensitive devices like wrist watches and similar.


The cutoff voltage of the SR41 battery is also dependent on the cutoff voltage of the device being powered, but it is usually around 1.2 volts - when the voltage of the silver-oxide battery falls below 1.25 volts, and especially below 1.2 volts, it begins to decline fast.


Silver-oxide SR41 batteries were frequently built in low-drain and high-drain configurations, with low-drain SR41 batteries intended for watches and similar devices that operate continuously at very low currents and high-drain SR41 batteries intended for devices that require relatively high currents on a regular basis.


With technological advancements, most current SR41 batteries are constructed as multi-drain batteries.


For example, the Energizer 392/384 battery (external link, PDF datasheet) has a nominal voltage of 1.55 volts and a typical capacity of 44 mAh when drained down to 1.2 volts using a 22 k load at 21°C.


Silver-oxide SR41 batteries have a longer shelf life than alkaline LR41 batteries; when stored at 68°F (20°C), a good SR41 battery has an expected shelf life of 6-8 years, occasionally even more.
