Specifications for an LR41 Battery: If you’re wondering if you need your electronic device’s LR41 button cell battery, learning about the battery requirements will give you an idea of whether it’s the right option. In general, LR41 batteries are used for small electronic devices, such as watches, which require a very compact power source. Because many batteries have the same size and similar specifications, you can swap an LR41 battery with many cells you might see on the market that are different.
LR41 Battery is an alkaline battery-shaped button with a nominal voltage of 1.5V.
This Alkaline Batteryis common in watches or other small toys and provides high voltage, high capacity, and superior low-temperature qualities superior.
This alkaline button cell battery gives the devices you use every day long life, watches, calculators, pen, electronic toys, pocket radios, etc. Generally, The LR41 Button Batteryis a non-rechargeable and alkaline battery.
What is LR41 Battery?
Batteries are the powerhouse of most handheld devices and they come in many sizes. The smallest of them are normally referred to as Button Batteries or coin cells.
They are given this name because of their miniature size. Technically, however, these batteries are called LR41.
LR41 batteries get their name from the alkaline chemicalcomponent involved in their manufacturing. The ‘L’ in ‘LR’ refers to ‘Alkaline chemical’ and ‘R’ to the ‘Round shape’.
LR41 batteries are non-rechargeable and need to be replaced with new ones once their charge has been consumed. A typical LR41 battery has a shelf-life ranging from 6 months to 5 years.
It depends on the quality of chemicals used to protect the cells’ charge from leaking. All LR41 batteries come with a uniform 1.5V of full charge.
The capacity of LR41 batteries varies from the other depending on the manufacturer who is producing them.
LR41 batteries are most commonly used to power small objects such as medical instruments, wristwatches, games and gadgets, flashlights, laser sights, pointers, toys, and electronic books, etc.
LR41 Battery Uses
LR41s are used in a range of electronic devices, but almost exclusively in small devices with limited power needs.
Devices that may use an LR41 include watches, clocks, laser pointers, interactive children’s books, thermometers, digital voice recorders, glucometers, cholesterol testers, and children’s toys.
This isn’t an exhaustive list, though, and if your device takes an LR41 battery, it should be indicated in the manual or on the packaging.
It’s worth noting that a device may take multiple LR41 batteries stacked one on top of the other, rather than just a single cell.
This increases the voltage and power output for more energy-intensive applications.
LR41 Voltage and Capacity
The main LR41 battery specs you’re likely to need are the voltage and capacity of the cells.
The voltage of a battery tells you the difference in electrical potential between the two terminals of the battery and is expressed as a number in volts.
The capacity tells you how much current it can provide for a specified period of time, expressed in milliamp-hours (mAh), with milliamp meaning “one-thousandth of an amp.”
The LR41 voltage is 1.5 V, but for a brand new battery, this can be 1.55 V or even up to 1.62 V.
The capacity of an LR41 battery ranges from 25 mAh to 32 mAh, for alkaline forms of the battery and depending on the cut-off point chosen (1.2 V or 0.9 V) and the specific cell.
For silver oxide versions of the battery, the capacity can range from 38 to 45 mAh.
The physical size of an LR41 battery is consistent across different cells.
The battery is a circular disc-shaped cell, so its size can be expressed as a diameter (the distance from one edge of the circle to the opposite edge, passing through the center) and the height of the battery.
The diameter of an LR41 battery is 7.9 mm (5/16″) and the height from top to bottom is 3.6 mm (9/64″). However, this height measurement includes the button section protruding up from the center, without this the height is 3.2 mm (1/8″).
LR41 batteries are alkaline batteries, but there are batteries that are similar enough to be interchangeable that use silver oxide chemistry.
For most applications, the difference between these two won’t be important, but silver oxide versions have larger capacities (as described in the “LR41 Voltage and Capacity” section) so these are better for devices with a higher power drain.
It’s best to look for LR41 batteries that are marked with zero percent Hg, meaning that they are free from mercury. This is for safety purposes in the event of leaking.
Alternate Names for LR41 Batteries
The LR41 battery can be interchanged with a range of batteries with different names.
For example, the LR41 is an AG3 battery equivalent, and can also be used interchangeably with SR41, SR41SW, 392, 392A, 192, 384, 92A, G3, GP192, V36, V36A, V3GA, LR736 and CX42 cells.
