Since the LR41 battery is the same as the AG3 battery, it can be safely replaced with the 392, 392A, G3, V36, V36A, SR41, SR41SW, V3GA, 192, 384, 92A, GP192, LR736 and CX42 batteries. All of these batteries are about the same size and give off about the same amount of energy, so it usually doesn’t matter which one you choose. Still, silver oxide batteries like the SR41 usually have more power than LR41 batteries. This makes them a great choice for electronics that need more power. One of the easiest equivalents to find in stores is the 384/392B.
LR41 Batteries and What Can Be Used Instead
Because LR41 batteries are so small, they are often used to power watches, small medical devices, interactive cards and books, toys, laser pointers, and more. They can be put on top of each other easily to get more power and voltage. Even though the battery says it has a voltage of 1.5 volts, new LR41 batteries can have a charge of up to 1.62 volts.
All LR41 batteries and their equivalents have a 9.9-millimeter diameter and a 3.6-millimeter height so that they can be used in many different electronic devices (3.2 millimetres if you exclude the height of the button).
Alkaline Batteries
LR41 batteries are made from alkaline. That means they use zinc and manganese dioxide as electrodes and pass electrons through an alkaline solution, like potassium or sodium hydroxide, to make power. People like alkaline batteries because they can hold a lot of energy for a long time. Most of these batteries don’t contain mercury, so they are better for the environment and can be thrown away at home without worrying about toxic chemicals leaking out. If a battery is mercury-free, it will say “zero percent Hg” on the package.
All over the world, people use alkaline batteries a lot. Most AAA, AA, C, D, and 9V batteries sold in stores are made of alkaline, and the ones that aren’t are usually marked in a big way. Most alkaline batteries are “primary,” which means they only work once and then have to be thrown away. Some alkaline batteries are secondary batteries, which means they can be charged again and again. However, you should never try to charge a battery that doesn’t say it can be charged again and again on the package. For batteries that can be charged again and again, you also need to use the right charger.
Silver Oxide Batteries
The SR41 battery, which uses silver oxide and zinc as its electrolytes, is often used instead of the LR41 battery. Instead of an alkaline solution, potassium hydroxide or sodium hydroxide is used as the electrolyte. SR batteries are used for many of the same things as LR41 batteries, like cash registers, watches, calculators, film cameras, microcomputers, and other portable electronics that need a bit more power than an alkaline battery can provide.
This is because an SR battery can hold almost twice as much energy as an alkaline battery. They have a flat discharge, which means they give off energy in a more even way than alkaline batteries, which can go from giving off a lot of energy at first to less and less as time goes on. Because of this, silver oxide batteries are great for powering electronics that are more sensitive and need a steady flow of power. On top of that, they usually last for about ten years after they are made.
Other Batteries
There are other types of “button batteries” besides alkaline and silver oxide, but they don’t get used as much. Even though mercury oxide batteries have less voltage than alkaline ones, they can hold more power. Still, the fact that these batteries were dangerous meant that they were no longer used.
Zinc air batteries are unusual because they use the chemical reaction that happens when zinc is exposed to oxygen in the air. They have a higher capacity than silver oxide batteries and almost as much voltage as an alkaline battery. But they stop working when the electrolyte in them dries out. Most of the time, they are used in hearing aids.
