Wondering if you need your electronic device’s LR41 button cell battery? Well learning about the battery requirements will help you know whether it’s the right option or not. So what are LR41 batteries? LR41 batteries are used for small electronic devices like watches, which require a very compact power source. Since many batteries have the same size and similar specifications, you can swap an LR41 battery with many cells you may see in the market which is different.
An LR41 battery is an alkaline battery-shaped button that has a nominal voltage of, 1.5V. This Alkaline battery is quite common in watches or other small toys and offers high voltage, high capacity, and superior low-temperature qualities superior. With an alkaline button cell battery, your everyday devices have a long life. These include watches, calculators, pens, electronic toys, pocket radios, etc. Generally, the LR41 button battery is a non-rechargeable and alkaline battery.
So what can you do with an LR41 battery?
LR41 Battery Uses
LR41 is used in a range of electronic devices. However, they are mostly used 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. However this is not an exhaustive list and if your device takes an LR41 battery, it should be indicated in the manual or even on the packaging. It is good to understand that a device is capable of using multiple LR41 batteries stacked one on top of the other instead of just a single cell. Now, this increases the voltage and power output for more energy-intensive applications.
LR41 Voltage and Capacity
The main LR41 battery specs you’ll likely need are the voltage and capacity of the cells. The voltage of a battery intimates you of the difference in electrical potential between the two terminals of the battery and is expressed as a number in volts. Now the capacity tells you how much current it can offer for a specified period of time. This is expressed in milliamp-hours (mAh), with milliamp implying “one-thousandth of an amp”.
The LR41 voltage is 1.5 V. However 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. But this is dependent on the cut-off point chosen (1.2 V or 0.9 V) as well as the specific cell. If it is the silver oxide version of the battery, the capacity can range from 38 to 45 mAh.
LR41 Physical Dimensions
The physical size of an LR41 battery is quite consistent across different cells. The battery is a circular disc-shaped cell, as such 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”), as well as the height from top to bottom, is 3.6 mm (9/64”). Be it as it may, this height measurement includes the button section which protrudes up from the center without this the height is 3.2 mm (1/8”).
LR41 Chemistry
Even though LR41 batteries are alkaline batteries, there are still batteries that are similar enough to be in rechargeable and uses silver oxide chemistry. For most applications, the difference between these two is not that important. However, silver oxide versions have larger capacities (as described in the “LR41” Voltage and Capacity” section). As such these are better for devices with a higher power drain.
When going for the LR41 batteries, it is best to look for LR41 batteries that are marked with zero percent Hg. This implies that they are free from mercury. This makes for safety purposes in the event of leaking.
So what are the alternate names for LR41 batteries?
Alternate Names for LR41 Batteries
There is various range of batteries with different names which the LR41 battery can be interchanged with. For instance, 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.
