What is an LR41 battery?

An LR41 battery is a small button cell battery that is commonly used in a variety of small electronic devices such as watches, calculators, and toys. The LR41 battery is a member of the LR (alkaline) battery family and is also known as an AG3 battery. It is a round, flat battery that measures approximately 7.9 mm in diameter and 3.6 mm in height.

The LR41 battery is a 1.5 volt alkaline battery that provides long-lasting power to small electronic devices. It is commonly used in devices that require a low drain current, such as LED keychains, laser pointers, and small calculators. The LR41 battery is also used in devices that require a higher drain current, such as small flashlights and digital thermometers.

One of the advantages of the LR41 battery is its small size, which makes it ideal for use in small electronic devices. The LR41 battery is also relatively inexpensive and widely available, making it a popular choice for consumers.

However, the LR41 battery does have some limitations. It has a relatively low energy density, which means it has a shorter lifespan than other types of batteries. The LR41 battery is also not rechargeable, which means it must be replaced when it runs out of power.



The LR41 battery is a small, versatile battery that is widely used in a variety of small electronic devices. While it may not provide the longest lifespan, it is a cost-effective and reliable power source for low to moderate drain devices.

LR41 vs. LR44 batteries what's the difference

The LR41 and LR44 batteries are both part of the LR (alkaline) battery family and are commonly used in small electronic devices such as watches, calculators, and toys. While these two batteries are similar in many ways, there are some key differences between them.

The main difference between the LR41 and LR44 batteries is their size and energy capacity. The LR41 battery is a smaller battery that measures approximately 7.9 mm in diameter and 3.6 mm in height, while the LR44 battery is larger and measures approximately 11.6 mm in diameter and 5.4 mm in height. The larger size of the LR44 battery means it has a higher energy capacity and can provide more power than the LR41 battery.

Another difference between these two batteries is their voltage. The LR41 battery is a 1.5 volt battery, while the LR44 battery is a 1.5 volt or 1.55 volt battery, depending on the manufacturer. This slightly higher voltage can make the LR44 battery more suitable for devices that require a higher voltage to operate.

In terms of use, both the LR41 and LR44 batteries are commonly used in small electronic devices with low to moderate drain currents. However, because the LR44 battery has a higher energy capacity, it may be a better choice for devices with higher drain currents, such as small flashlights.


Another consideration when choosing between the LR41 and LR44 batteries is their availability and cost. The LR41 battery is generally more widely available and less expensive than the LR44 battery, which may make it a more practical choice for some consumers.

The LR41 and LR44 batteries are both commonly used in small electronic devices, but there are some key differences between them in terms of size, energy capacity, and voltage. When choosing between these two batteries, it is important to consider the specific needs of your device and your budget.

How to properly dispose of LR41 batteries?

Proper disposal of LR41 batteries is important for both environmental and safety reasons. These batteries contain toxic chemicals such as mercury, cadmium, and lead, which can be harmful if they are released into the environment. Here are some tips for disposing of LR41 batteries safely and responsibly:

Recycle: Many municipalities have recycling programs that accept alkaline batteries for recycling. Check with your local recycling center or waste management department to see if they accept LR41 batteries.

Household hazardous waste collection: Many communities offer household hazardous waste collection events where you can drop off items such as batteries, paint, and cleaning supplies for safe disposal. Check with your local government to see if they offer this service.

Battery drop-off locations: Some retailers and battery manufacturers offer free battery drop-off locations for recycling. Check with your local electronics store or battery manufacturer to see if they provide this service.
