The AG10 battery is a small 1.5V button cell used in many compact electronic devices. Although it looks simple, finding the correct replacement can sometimes be confusing because the same physical battery may be sold under several different names. You may see names such as AG10, AG 10, LR1130, LR54, or other manufacturer-specific codes when searching for the same basic battery size.
People looking for an AG10 battery equivalent often want to know one simple thing: "Which battery can replace my AG10?" The answer depends on both electrical characteristics and physical dimensions. A battery can have a similar voltage but still be the wrong replacement if its diameter, thickness, chemistry, or discharge characteristics do not match the original cell.
This guide explains the AG10 battery in plain English. It covers the most common AG10 batteries, AG 10 batteries, battery equivalents, button-cell replacements, LR1130 cross references, Duracell-related alternatives, and the difference between a true equivalent and a battery that is merely similar.
One important point should be made at the beginning: an AG10 is normally a 1.5V alkaline button cell. It should not be confused with a 10V battery. Searches for 10 battery or 10v battery can sometimes lead to unrelated products, so checking the complete battery marking is important before ordering a replacement.
What Is an AG10 Battery?
An AG10 battery is a small cylindrical button battery designed for low-power electronic devices. It normally uses alkaline chemistry and provides a nominal voltage of 1.5 volts.
The battery is compact, lightweight, inexpensive, and widely available. Its small size makes it suitable for devices where a conventional cylindrical battery would be too large.
The most useful specifications to remember are:
- Battery type: Alkaline button cell
- Nominal voltage: 1.5V
- Common designation: AG10
- Common IEC designation: LR54 / LR1130 family
- Shape: Round button cell
- Polarity: Positive and negative faces are clearly marked by construction
- Typical use: Small electronic and consumer devices
Exact capacity can vary between manufacturers and operating conditions, so capacity should not be treated as a single universal number for every AG10 battery.
AG10 Battery Size and Dimensions
Physical dimensions are one of the most important parts of an AG10 equivalent search.
An AG10/LR1130-type battery is approximately 11.6 mm in diameter and 3.1 mm in height. Small differences may exist between manufacturers, but these dimensions are useful when identifying the battery family.
The compact form factor is what makes this cell useful in small devices such as watches, calculators, electronic toys, miniature lights, measuring devices, and other low-power equipment.
When looking for an AG10 battery replacement, do not compare voltage alone. The replacement should also physically fit the battery compartment.
AG10 Battery Equivalent: Which Battery Replaces AG10?
The most common equivalent designations associated with an AG10 alkaline button cell include LR1130 and LR54.
These designations are particularly useful when searching for a replacement because battery manufacturers and retailers do not always use the same naming system.
In practical terms, you may encounter listings such as:
- AG10 battery
- AG 10 battery
- LR1130
- LR54
- 1.5V button battery
- 1.5V alkaline button cell
However, an important distinction exists between an electrical equivalent and a cross-reference number. A cross-reference may indicate a similar physical format, while chemistry and discharge behavior can still differ.
AG10 vs LR1130
AG10 and LR1130 are commonly used interchangeably in battery searches. LR1130 is an IEC-style designation associated with a 1.5V alkaline button cell of this size.
This is why searching for AG10 battery equivalent LR1130 often produces the same physical battery family.
If your original device specifies AG10, LR1130, or LR54, the safest approach is to compare the complete markings and physical dimensions before purchasing.
Do not assume that every battery with "1130" in its name has identical chemistry. Some silver-oxide cells use related size designations but have different electrical characteristics.
AG10 vs LR54
LR54 is another common designation associated with the AG10-size alkaline button-cell family.
For consumers, this can be helpful because a store may have LR54 batteries but not label them as AG10.
When searching online, combining terms such as AG10 LR54, AG10 LR1130, or AG10 replacement can make it easier to locate the correct battery family.
Even when two names refer to the same general size and chemistry, always check the manufacturer's specifications when the application is sensitive to voltage or battery performance.
What Does 1.5 V Alkaline Button Cell Mean?
The phrase 1.5 V alkaline button cell describes three basic characteristics of the battery.
1.5V describes its nominal voltage.
Alkaline describes its battery chemistry.
Button cell describes its small, flat, round physical form.
This combination is exactly why the AG10 is useful in compact electronics.
A button cell is different from a standard AA or AAA battery not only because of its shape, but also because the device is designed around the electrical and physical properties of the small cell.
AG10 Battery Voltage
The nominal voltage of an AG10 alkaline battery is 1.5V.
This number is important when choosing a replacement.
A replacement battery with a significantly different nominal voltage may cause a device to malfunction or, in some cases, create an unsafe operating condition.
For this reason, an AG10 should generally be replaced with a battery specified for the same voltage and compatible chemistry unless the equipment manufacturer explicitly allows another chemistry.
AG10 Battery vs 10V Battery
The search phrase 10v battery can create confusion.
An AG10 battery is a 1.5V button cell. It is not a 10V battery.
The number "10" in AG10 is part of the battery designation. It does not mean the battery produces 10 volts.
This is a useful distinction when searching for replacement batteries online. A search for "10 battery" may produce many unrelated results, while AG10 battery, AG10 LR1130, or AG10 1.5V is much more specific.
AG10 Battery Replacement: What Should You Check?
Before purchasing an AG10 battery replacement, check five basic things:
- Voltage
- Battery chemistry
- Physical dimensions
- Polarity
- Manufacturer or device specification
If all five are compatible, the replacement is much more likely to work correctly.
The easiest mistake is to focus only on the label. The easiest way to avoid that mistake is to compare the complete specification.
AG10 Battery Substitute Options
When people search for an AG10 battery substitute, they usually mean one of two things.
The first is a battery with the same size, voltage, and chemistry but a different commercial name. This is the most straightforward type of substitute.
The second is a battery with a similar size and voltage but a different chemistry, such as a silver-oxide cell.
The second option requires more care.
Silver-oxide button cells can have a nominal voltage around 1.55V and may provide a more stable voltage profile during discharge. They can therefore be attractive in certain precision applications. However, they should not automatically be treated as identical to an alkaline AG10 simply because the physical dimensions are similar.
For ordinary replacement, the safest approach is to follow the device manufacturer's specified battery type.
AG10 Equivalent and Silver Oxide Cross References
One reason AG10 cross-reference searches become confusing is that alkaline and silver-oxide batteries can share similar physical dimensions.
You may encounter designations such as SR1130, 389, or 390 in discussions of batteries that have similar dimensions to an LR1130-type cell.
These are not simply different names for the same alkaline chemistry. The chemistry is different.
This means a battery can be a physical cross without being a perfect chemistry equivalent.
That distinction is particularly important in watches, measuring instruments, medical or laboratory equipment, and other devices where stable voltage characteristics may matter.
AG10 and IR1130: A Common Search Confusion
The term IR1130 or Ir1130 sometimes appears in online searches for button batteries. In many cases, users may actually be referring to LR1130 or another 1130-size battery designation.
This is a good example of why reading the original battery marking carefully matters.
The letters "LR" and "IR" are not interchangeable just because they look similar in a product listing or handwritten label.
If the original battery says LR1130, search specifically for LR1130 AG10 equivalent rather than relying on an uncertain "IR1130" spelling.
AG10 Batteries for Small Electronic Devices
AG10 batteries are designed for applications that require relatively small amounts of power from a compact package.
Common examples can include:
- Small calculators
- Electronic toys
- Miniature LED products
- Small clocks
- Compact measuring devices
- Some watches and instruments
- Small electronic novelty products
- Low-power consumer electronics
The exact applications vary by manufacturer and device design.
The important concept is that AG10 is intended for relatively low-power applications where small size is more important than high current capacity.
AG10 Battery Capacity
Battery capacity is normally expressed in milliamp-hours, or mAh.
However, the advertised capacity of a small button cell should not be interpreted as a fixed amount of energy available in every application.
Actual battery performance depends on:
- Load current
- Operating temperature
- Cutoff voltage
- Device design
- Battery age
- Storage conditions
- Manufacturer
A battery may provide a different usable capacity in a low-current calculator compared with a device that draws current in short but relatively strong pulses.
For this reason, battery capacity should be compared using manufacturer test conditions whenever possible.
AG10 Battery Shelf Life and Storage
Like other alkaline batteries, AG10 cells slowly lose charge over time even when they are not being used.
Storage conditions influence long-term performance.
For best results, unused button cells should generally be kept in their original packaging in a cool, dry environment and protected from excessive heat and moisture.
Do not store loose button cells together with metal objects such as coins, keys, or tools. Accidental contact between battery surfaces and conductive objects can create an unintended electrical path.
Why AG10 Battery Polarity Matters
Button cells have two terminals: positive and negative.
The flat face is normally marked with a "+" symbol and serves as the positive terminal. The opposite side is the negative terminal.
When installing an AG10 replacement, match the polarity markings inside the device.
Installing a battery backward may prevent the equipment from operating. Some electronic devices include protection against reverse polarity, but that protection should never be assumed.
How to Identify an AG10 Battery
If you have a loose button cell and are unsure whether it is an AG10, look for the printed marking.
Common identifiers can include:
- AG10
- LR1130
- LR54
- 1.5V
- Manufacturer-specific part numbers
You can also measure the battery's diameter and thickness using a suitable measuring tool.
However, physical measurement alone is not enough to identify the chemistry. Two cells can have almost identical dimensions while using different electrochemical systems.
AG10 Cross Reference: Why Manufacturer Names Differ
Battery manufacturers use different naming systems for commercial products. One company may emphasize an IEC designation, while another may use a consumer-friendly code.
That is why searching only one code can sometimes make a common battery appear difficult to find.
A better search strategy is to combine the major designations:
- "AG10 battery"
- "AG 10 battery"
- "LR1130 battery"
- "LR54 battery"
- "AG10 equivalent"
- "AG10 replacement"
- "AG10 cross reference"
- "1.5V button battery"
This approach makes it easier to identify equivalent products from different brands.
Duracell AG10 Equivalent: What Should You Look For?
Users sometimes search specifically for a Duracell AG10 equivalent. The important point is that the brand name alone does not determine whether a battery is suitable.
Instead, compare the manufacturer's battery designation, voltage, dimensions, chemistry, and application information.
For example, some Duracell button cells use silver-oxide chemistry and may have designations associated with the SR1130/389/390 family. These products can have similar physical dimensions to AG10/LR1130 batteries but should not automatically be considered identical alkaline replacements.
If the device specifically calls for an alkaline AG10 or LR1130, look for a replacement that matches that chemistry unless the device manufacturer permits an alternative.
AG10 vs AG13
Another common source of confusion is the difference between AG10 and AG13.
Both are alkaline button-cell designations, but they are not the same physical size.
This means an AG13 battery should not automatically be used as an AG10 replacement simply because both batteries are labeled "AG."
The battery compartment is designed around a specific diameter and thickness. A cell that is too thick may not fit, while a cell that is too thin may not make reliable contact.
AG10 vs AG12 and Other Button Cells
The same principle applies to other AG-series batteries.
AG10, AG12, AG13, and other button-cell designations can look similar in a product catalog, but their dimensions and specifications may differ.
When replacing a battery, never select a cell based solely on the fact that it begins with "AG."
Instead, compare the complete designation and dimensions.
Is Every 1.5V Button Battery an AG10?
No.
1.5V button battery describes a broad category, not one specific battery model.
There are many 1.5V button cells with different diameters, thicknesses, capacities, and applications.
An AG10 is only one member of this larger family.
For example, two 1.5V button batteries can have the same nominal voltage but completely different physical dimensions. One may fit a device while the other does not.
Therefore, "1.5V" is only one part of the identification process.
Can You Use a Different Chemistry as an AG10 Substitute?
Sometimes a different chemistry can physically fit the same battery compartment, but that does not automatically make it the correct replacement.
Alkaline and silver-oxide button cells have different discharge characteristics.
An alkaline AG10 typically starts around its nominal 1.5V range and its voltage gradually changes as the battery discharges. Silver-oxide cells generally provide a flatter discharge profile and can be preferred in applications where stable voltage is important.
Therefore, the correct question is not simply "Does it fit?"
The better question is:
"Does the replacement have compatible voltage, dimensions, chemistry, polarity, and electrical behavior for this device?"
AG10 Battery Safety
Button cells are small, but they should be handled carefully.
Never intentionally short-circuit an AG10 battery. Do not heat, crush, puncture, disassemble, or recharge a standard non-rechargeable alkaline button cell.
Keep button batteries away from young children and pets. Small button cells can be extremely dangerous if swallowed.
Used batteries should be disposed of according to local battery-recycling or waste-disposal requirements.
When installing several batteries, do not mix old and new cells or different battery chemistries unless the equipment manufacturer specifically permits it.
Common AG10 Battery Replacement Mistakes
Choosing by Voltage Only
A 1.5V battery is not automatically an AG10. Diameter and thickness also matter.
Choosing by Physical Size Only
A physically similar cell may use a different chemistry and have different discharge characteristics.
Confusing AG10 With AG13
Similar names do not mean identical dimensions.
Confusing LR1130 With Other 1130 Cells
Related size numbers can appear across different battery chemistries. Always check the complete designation.
Assuming Every Brand Uses the Same Name
Commercial battery names vary by manufacturer and market.
Searching for "10V Battery"
AG10 is a battery model designation. It is a 1.5V cell, not a 10V battery.
AG10 Battery Comparison Table
| Designation | General Chemistry | Nominal Voltage | Relationship to AG10 |
|---|---|---|---|
| AG10 | Alkaline | 1.5V | Primary designation |
| LR1130 | Alkaline | 1.5V | Common equivalent designation |
| LR54 | Alkaline | 1.5V | Common cross-reference |
| SR1130 | Silver oxide | About 1.55V | Similar physical size, different chemistry |
| 389 | Silver oxide | About 1.55V | Related physical-size family |
| 390 | Silver oxide | About 1.55V | Related physical-size family |
This table is intended to explain the cross-reference concept. For a specific device, always confirm the manufacturer's recommended battery type.
How to Choose the Best AG10 Battery
If several AG10 batteries are available, price should not be the only deciding factor.
A practical selection checklist is:
- Confirm that the battery is an AG10 or compatible LR1130/LR54 type.
- Confirm the nominal voltage is 1.5V.
- Confirm the chemistry is appropriate for the device.
- Check the battery dimensions.
- Check the expiration or best-before date.
- Buy from a reliable source.
- Store unused cells correctly.
For low-drain devices, a fresh alkaline AG10 can provide a practical and economical solution. For devices that require a more stable voltage profile, the manufacturer may specify a silver-oxide cell instead.
AG10 Battery and Device Performance
A battery is only one part of the power system.
How long an AG10 lasts depends heavily on the device's current consumption.
A calculator that draws very little current may operate for a long time from a small button cell. Another device using the same battery size but drawing more current may consume the battery much faster.
This is why battery life cannot be predicted accurately from the battery model alone.
A useful simplified relationship is:
Battery life ≈ usable battery capacity ÷ average load current
Real battery life is more complicated because capacity changes with discharge current, temperature, cutoff voltage, and battery age.
Why AG10 Battery Equivalents Are So Common Online
Small button batteries are sold through many different markets, and each market can use different product naming conventions.
A manufacturer may use an IEC code, a retail code, or a proprietary part number. Retailers may then list several compatible names in the same product description.
This is why a single physical battery can appear under several search terms.
For buyers, this is actually useful. If an AG10 battery is unavailable locally, searching for LR1130 or LR54 can reveal compatible products from other brands.
AG10 Battery: The Most Useful Cross-Reference Strategy
Instead of asking only "What is the AG10 equivalent?", use a three-level check.
Level 1: Electrical match
Check nominal voltage and chemistry.
Level 2: Physical match
Check diameter, thickness, and polarity.
Level 3: Application match
Check the device manufacturer's instructions and the expected discharge characteristics.
A replacement that passes all three levels is much more reliable than one chosen from a simple online cross-reference list.

Final Guide to AG10 Battery Equivalents and Replacements
The AG10 battery is a small but widely used 1.5V alkaline button cell. Its compact dimensions make it useful for many low-power electronic devices, while its multiple commercial designations can make replacement searches confusing.
The most important AG10 cross-reference terms are LR1130 and LR54. These names are commonly associated with the same general 1.5V alkaline button-cell family.
However, not every similarly sized button cell is a perfect equivalent. Silver-oxide batteries such as cells in the SR1130/389/390 family can have similar physical dimensions but use a different chemistry and provide different discharge characteristics.
When choosing an AG10 battery substitute, the safest method is to compare more than the name. Check voltage, chemistry, dimensions, polarity, and the requirements of the equipment.
Remember that AG10 is not a 10V battery. It is normally a 1.5V alkaline button cell. The "10" is part of the battery's identification code.
For everyday replacement searches, terms such as AG10 battery equivalent, AG10 replacement, AG 10 batteries, LR1130 battery, LR54 battery, AG10 cross reference, and 1.5V button battery are useful because different manufacturers and retailers may use different names for closely related products.
The best replacement is ultimately not the battery with the closest-looking name. It is the battery that provides the correct voltage, compatible chemistry, correct physical size, proper polarity, and suitable electrical performance for the device.
