What is the Equivalent to a LR41 Battery?

The LR41 battery is a relatively small button cell battery, most commonly used for small consumer devices. It is made by an array of manufacturers in both private-label and branded configurations.

This battery usually comes in a nominal charge of 1.5 volts but can vary depending on the manufacturer. These batteries essentially contain a blend of magnesium dioxide, zinc, and an alkaline electrolyte solution.

This alkaline chemical is what the battery gets its name from. While the ‘L’ in the ‘LR’ stands for ‘Alkaline chemical,’ the ‘R’ denotes its round shape. These batteries have a shelf-life of 6months to 5 years and are non-rechargeable. The longevity mainly depends on the chemicals that are used to safeguard the charge of the cells from leaking.

What are these Batteries Used for?

There is a hoard of devices that use the LR41 battery. These are mostly small devices that require limited power. Ranging from various consumer products like calculators, electronic toys, watches, flashlights, and laser pointers. These batteries are also utilized for several medical devices.

One of the most popular medical devices, especially after the pandemic, is a digital thermometer. Others include glucometers and cholesterol testers. However, this is not the complete list. You can look in the manual or packaging of the product you are using to see if it requires an LR41 battery.

It is not uncommon for a device to require more than one LR41 battery, given its minimal power output. With these batteries stacked one above the other, it can offer more voltage for energy-intensive applications.

Alternate Names for LR41

While LR41 has its own set of appliances it works with, it can commonly be interchanged with other similar ones. These are a few alternative models this battery can be used for:

  • AG3
  • SR41SW
  • SR41
  • 192
  • 392A
  • 92A
  • 384
  • GP192
  • G3
  • V36A
  • V36
  • LR736
  • V3GA
  • CX42

LR41 Capacity and Voltage

To find an LR41 battery amongst the several similar batteries, you will need its capacity and voltage. The voltage (V) further tells you the difference between the electrical potential of the two terminals. However, the capacity tells you how much current it can offer for the stipulated amount of time. This is expressed in milliamp-hours (mAh). Milliamp stands for a one-thousand share of one ampere.

While the standard voltage of an LR41 battery is 1.5V, for a brand new model, it can rise up to 1.61V. For alkaline forms of an LR41, the capacity ranges from 25 to 32 mAh. However, for a silver oxide variant, it can be up at 38 to 45 mAh.  The capacity primarily depends on the specific cell used and it’s cut off point, usually 0.9 V or 1.2 V.

Common Misconception

Due to its large number of manufacturers, it is very easy to get confused between different designations of the same battery. However, mix-ups are not that rare, the most common one being between 392 and LR41 batteries. While they are almost identical in appearance and size, they are used for totally different purposes.

The LR41 batteries are used for devices that require high-drain power usage, while 392 caters to longevity more than high power. Even though the LR41 is significantly cheaper than 392s, the increased drain power flow design of the former will not efficiently power up a device that requires a more consistent and slower flow.

This further makes it vital for you to check the specifications and requirements of the device that you buy. More importantly, if the batter will sufficiently be able to power it up and keep it working. That being said, LR41 batteries are practical and very efficient when paired with the right device for the right purpose.
