What Is an LR44 Battery?
The LR44 is an alkaline button cell battery with a nominal voltage of 1.5 volts and a standard size of 11.6 mm in diameter and 5.4 mm in height. It’s also commonly referred to by other codes like AG13, A76, or 157, depending on the manufacturer and regional labeling systems.
This battery type powers a broad range of devices due to its small size and consistent energy delivery. However, different devices may list other battery codes in their manuals, leading many users to wonder whether these alternatives can be safely used in place of an LR44.
Why Look for an LR44 Equivalent Battery?
Availability and Regional Naming Differences
One of the primary reasons people search for LR44 equivalents is the variation in naming conventions across manufacturers and regions. For example, what’s called an LR44 in one country might be labeled AG13 elsewhere.
Performance Considerations
Some alternatives to LR44 may offer slightly better or worse performance depending on the chemical composition—like silver oxide versus alkaline versions. We'll get into those details shortly.
Cost and Brand Preferences
Certain battery brands may price their LR44 equivalents more affordably. Others may focus on longevity and offer premium versions. Having multiple choices allows consumers to make more cost-effective decisions.

Common LR44 Equivalent Battery Names
There are dozens of different labels that represent the same size and voltage characteristics as LR44. These include:
AG13
A76
L1154
157
LR1154
G13
RW82
GPA76
Each of these names typically refers to batteries that are physically the same size and have the same voltage output. However, the internal chemistry and discharge curves may vary slightly depending on whether it’s an alkaline or silver oxide version.
LR44 vs AG13: Are They the Same?
Physical Dimensions and Voltage
Yes, LR44 and AG13 batteries are essentially the same in size and voltage, both offering 1.5V and a similar shape. AG13 is simply another code used predominantly by Asian manufacturers.
Chemistry Differences
Both AG13 and LR44 can come in either alkaline or silver oxide versions. The chemistry might not always be specified clearly on packaging, so checking technical specifications or datasheets can help ensure you're getting what you need.
LR44 vs A76: Interchangeable?
Absolutely. A76 is Duracell’s naming convention for their version of the LR44 battery. It’s designed to be 100% interchangeable with the LR44 in all devices that require it.
Silver Oxide vs Alkaline LR44 Equivalents
Not all LR44 equivalents are chemically identical. Here’s a comparison between the two common types:
Feature |
Alkaline (LR44, AG13) |
Silver Oxide (SR44, 357) |
Voltage |
1.5V |
1.55V |
Discharge Profile |
Drops gradually |
Flat, more stable output |
Lifespan |
Shorter |
Longer |
Price |
Cheaper |
More expensive |
Suitable for |
General-purpose use |
Precision electronics |
If you're using a high-drain device like a laser pointer or glucometer, silver oxide alternatives are often a better choice than standard alkaline LR44 batteries.
Detailed Comparison of LR44 Equivalents by Brand
Energizer
Energizer’s equivalent is the A76 (alkaline) or 357/303 (silver oxide). The 357/303 provides longer life and a more stable voltage output.
Duracell
Duracell sells the A76 as an alkaline LR44 alternative and the D357 for silver oxide replacement.
Panasonic
Panasonic markets their LR44 as LR44P, offering both alkaline and silver oxide types depending on the SKU.
Sony
Sony equivalents are marked LR44 for alkaline and SR44 for silver oxide versions.
Maxell
Maxell offers LR44 and SR44W, the latter being the more premium silver oxide variant ideal for watches and timers.

How to Identify an LR44 Battery in Your Device
Many users aren’t aware of the specific battery model their device uses. Here's how to confirm if your device uses an LR44:
Check the user manual – It often lists compatible battery codes.
Look at the battery compartment – Codes are often printed inside.
Measure the old battery – If it’s 11.6 mm in diameter and 5.4 mm tall, it's likely an LR44 or equivalent.
Search online – Just type your device model plus “battery” to find specs.
Safe Usage of LR44 Equivalent Batteries
Using equivalents is safe as long as:
Voltage matches (1.5V or 1.55V)
Size is identical
Chemistry is compatible (alkaline for general use, silver oxide for sensitive equipment)
Mixing different battery chemistries in the same device is not recommended.
Tips for Buying LR44 Equivalent Batteries
Buy From Reputable Sellers
Avoid counterfeit batteries by purchasing from known vendors and checking for brand authenticity.
Pay Attention to Expiry Dates
Button cells have a shelf life. Always check expiry dates before purchasing large quantities.
Consider Bulk Packages
If you frequently use devices that require LR44 or equivalents, buying in bulk can be more economical.
Store Properly
Keep batteries in a cool, dry place to avoid leakage and degradation.

Are Rechargeable LR44 Batteries Available?
Yes, there are some rechargeable versions available, often marked as LIR44. These are 3.6V lithium-ion batteries—not direct drop-in replacements due to their higher voltage. Use these only if your device explicitly supports rechargeable 3.6V cells.
LR44 Equivalents for Watches
Silver oxide batteries are often preferred for watches due to their stable voltage. In this case, SR44, 357, or 303 are ideal equivalents to LR44.
LR44 Battery in Toys and Gadgets
Toys generally use alkaline batteries like AG13 or A76 because they are cheaper and sufficient for short-term use.
Environmental Impact of LR44 and Equivalents
Button batteries like LR44 often contain harmful materials and should be disposed of properly. Never throw them in household waste. Use local recycling programs or drop-off bins.
Final Thoughts on LR44 Equivalent Batteries
Finding the right equivalent battery to LR44 is easy once you understand the naming conventions and chemistry options. Whether you're replacing a watch battery or powering a toy, knowing that AG13, A76, and SR44 all serve similar roles gives you flexibility in choosing what’s available and affordable.
From alkaline to silver oxide, LR44 equivalents offer a wide range of performance, longevity, and brand choices. Just be sure to check the voltage and dimensions before making a switch.
As long as the specifications match, using an LR44 equivalent is a safe and efficient way to keep your devices running smoothly.
Whether you're shopping online or checking local stores, having this knowledge ensures that your device gets the power it needs without confusion. Always double-check compatibility, and you’ll find that LR44 equivalents work seamlessly in most cases.
The LR44 battery remains a staple in many devices, and thanks to its many equivalents, you’ll never be left without options.
