You probably picture a little silver disc when you think about the LR44 battery, the kind that powers calculators and watches. But there's more to this humble 1.5V alkaline button cell than you'd expect. In this guide, we are going to delve deep and discuss what makes the LR44 battery special, how it stacks up against other batteries like AG13, the 357, and the A76, and show you where to find the best LR44 battery equivalent for your needs.
What is an LR44 Battery?
The
LR44 is a very common and compact type of alkaline button
cell battery with a voltage of 1.5V. It's a popular button cell battery ideal for applications needing a compact, long-lasting, high performing power source, such as:
-
Digital thermometers
-
Laser pointers
-
Watches (pilas de reloj LR44)
-
Small flashlights
-
Calculators
-
Electronic toys
An LR44 battery is usually
11.6mm in diameter and
5.4mm high, which means that it is very easy to store away in small electronics.
LR44 Battery Equivalents: Are They All the Same?
If you are busy searching for a
replacement, you will generally find LR44 referenced by other names. This gets a little confusing. Let's break it down:

So, if you're wondering about LR44 vs AG13, they are practically the same battery with different names used by different manufacturers.
However, LR44 vs 357 brings a key difference: the 357 is a silver oxide battery, meaning it has a slightly higher and more stable voltage (1.55V) and lasts longer, especially in high-drain devices.
Popular Equivalent Names (Based on Brand or Region):
-
Duracell LR44 equivalent: Duracell 76A
-
Energizer LR44 equivalent: Energizer A76
-
Maxell: LR44
-
Rayovac: RW82
So if you're see LR44 button cell battery,
AG13 battery, or
A76, rest assured: they'll work for most of the same devices.
Are All LR44 Batteries the Same?
No. The difference between LR44 and SR44 lies in the chemistry. While LR44 is alkaline, SR44 is silver oxide and usually longer-lasting and better for constant voltage output.
Similarly, the difference between AG13 and LR44 is often just branding-but sometimes AG13 can be manufactured to slightly looser tolerances, depending on the producer.
When purchasing LR44, particularly online, keep an eye out for these:
-
Alkaline (LR44, AG13, A76): Inexpensive, lower capacity
-
Silver Oxide (SR44, 357): More costly, higher capacity
If you need an extended lasting and exact device (like a digital thermometer), a silver oxide LR44 replacement such as the 357 battery is likely to be preferable.
Common Questions
Q1: Are LR44 batteries the same as 357?
Not exactly. LR44 is alkaline, while 357 is silver oxide. They fit the same devices, but 357 lasts longer.
Q2: Is AG13 the same as LR44?
Yes, AG13 is just another name for LR44. Some regions or brands prefer AG13, but both are interchangeable.
Q3: Can I replace LR44 with A76?
Yes, A76 vs LR44 is just a naming difference. Both are 1.5V alkaline button cells.
Q4: What about L1154F vs LR44?
L1154F is also a common name for the LR44 battery, used by some Chinese manufacturers.
Q5: Are there different types of LR44 batteries?
Yes. There are alkaline (e.g., LR44, A76) and silver oxide (e.g., 357, SR44) types. Choose based on your device's power needs.
Conclusion: Choose the Right LR44 for Your Device
The 1.5V
LR44 alkaline button battery is a small but powerful workhorse energy cell of many portable devices. Whether you're purchasing these for your own use or are buying in bulk to resell, knowing the difference between LR44 vs 357, AG13 vs LR44, and other equivalent type batteries are extremely important for ensuring you are getting the right type of battery in your device.
For long-lasting results, consider choosing a silver oxide equivalent (e.g., 357 or SR44).
Otherwise, AG13 / A76 / LR44 will serve perfectly in most devices.
