The Simple But Powerful Power Source You Need To Know – LR44 Battery
It has a small footprint, but this LR44 battery is one of the most widely used button cell batteries on the planet. It operates the likes of digital thermometers, children's toys, wristwatches and some medical instruments. But what exactly is it? How to choose the right equivalent or replacement LR44 battery? So then, let's get into a little bit more about this tiny little tank of a battery.
The LR44 battery or AG13 button cell is an alkaline battery used in small electronic devices.Alkaline button cell battery chemistryMaterial of the positive electrode is silver oxide, the negative electrode is zinc powder, but are used the alkaline electrolytes such as potassium hydroxide and sodium hydroxide.
This battery works by a chemical reaction between the zinc and silver oxide. The LR44 battery can supply reliable electricity source with the electrical energy produced by this reaction.
What Is an LR44 Battery?
What is the LR44 battery – this is a 1.5 V alkaline button cell battery commonly used in small electronic devices such as calculators, small remote controls, etc. A coin battery is a (positive) electrode and an electrolyte of an insulating coin body. Its diameter is around 11.6mm and it's 5.4mm thick. 514: Because it's also the size and voltage of a watch battery, it's great for low-drain devices in need of a petite power source.

LR44 Battery Equivalent: What Can You Use Instead?
There are many codes and names for LR44 batteries, depending on the brand and chemistry. Here are the most common equivalent battery LR44 options:
AG13- is a widely recognized equivalent to the LR44 battery. It shares the same physical size (11.6mm x 5.4mm) and operates at 1.5V, making it a perfect substitute in most devices. AG13 is commonly found in toys, calculators, and small electronic gadgets. The main difference lies in the naming-AG13 is simply another label used by certain brands for the same battery type as LR44.
A76 - is another name for the LR44 battery, commonly used by well-known battery manufacturers like Duracell. It has the same size and 1.5V voltage, making it completely compatible with any device that requires an LR44. If you see A76 on packaging, you can confidently use it as a direct replacement for LR44 in your watches, remotes, and small electronics.
L1154- refers to a general category of 1.5V alkaline button batteries, and it's fully interchangeable with LR44. This label is often seen in international specifications or cross-reference charts. Whether it's printed as L1154F or L1154G, you can safely use this battery in any device that takes an LR44, as they have identical electrical and physical characteristics.
G13- is another designation for batteries with the same specifications as LR44. Although not as commonly labeled as AG13 or A76, G13 is often used in certain watch or hearing aid battery charts. It provides the same 1.5V output and physical size, meaning it's compatible with all LR44-powered devices.
357- is a silver oxide battery with the same dimensions as LR44 but a key difference in chemistry. Unlike the alkaline LR44, the 357 maintains a more stable voltage over time (1.55V) and lasts significantly longer. This makes the 357 a better choice for precision devices like watches or medical tools, though it tends to be more expensive.
SR44- is also a silver oxide button battery and is often seen as a high-end alternative to LR44. It delivers a stable 1.55V output and has a longer lifespan, making it ideal for sensitive electronics that require steady voltage. SR44 is particularly popular in watches and professional equipment, and it's fully compatible as an LR44 replacement if your device allows for silver oxide chemistry.
While the size is usually the same, there are chemistry differences. For example, SR44 and 357 batteries are silver oxide batteries, which tend to last longer and offer more stable voltage compared to alkaline LR44. If you're wondering about lr44 battery vs 357, the 357 is superior in longevity but often costs more.
LR44 Battery vs 357 Battery - Battery Performance Comparison
If you're using a basic watch or toy, the LR44 is a cost-effective and widely available choice. But for more sensitive or high-performance devices like digital watches or medical tools, the 357 silver oxide battery is the better option due to its stable voltage and longer life.
Here's a quick comparison to help you decide:

LR44 Lithium Battery: Is It a Thing?
Some users search for an LR44 lithium battery or lithium battery LR44 equivalent. While most LR44 batteries are alkaline, some lithium versions do exist but are rare. Lithium batteries typically offer higher voltage (3V), so they are not a direct replacement unless your device supports them.
LR44 Battery Pack and Price
Looking to save money? Buy in bulk! You can find an LR44 battery pack of 3, 5, or even 10 batteries for a very low cost. A lr44 battery 3 pack may cost just a few dollars.
LR44 battery price varies by brand and chemistry. Silver oxide versions (like 357) are more expensive but may be worth the cost in high-performance gadgets.
LR44 Coin Cell Battery: Small but Essential
Known also as an LR44 coin battery or LR44 coin cell battery, this battery belongs to the coin family because of its shape and size. Don't underestimate its importance-your favorite watch or toy may rely on it more than you think.
