Ⅰ AG13 Battery Basics

1.1 What is a AG13 Battery?

The AG13 battery is intended for devices that require a steady low power supply. They are most commonly utilized in hearing aids and electronic wristwatches. Because the power source resembles a tablet, the AG13 battery is sometimes known as a tablet.

AG13 batteries, also known as Alkaline Zinc Manganese button batteries, are mostly used in timepieces. They are equivalent in size and voltage to the SR44 batteries, commonly known as 357. They are also known as LR44, 157, A74, or LR 1154. The latter, on the other hand, are Silver Oxide batteries, which have a capacity of around three times as long a charge but a price that is three times as costly.

The standard voltage of an AG13 or LR44 battery is 1.5 volts, and the termination voltage is 0.9 volts. They have a capacity of 130mAh. The cell measures 11.6 x 5.4mm.

Alkaline Zinc Manganese has the chemical formula (-) / MnO2 (C) (+) Zn MnO2. Other industrial names for AG13 batteries include LR44, 157, A76, and LR1154.

1.2 AG13 Battery Specifications and Usage
The manganese-zinc battery AG13 is a type of manganese-zinc battery. Manganese-zinc is a well-known chemical element that functions as an energy generator. This kind has a low nominal capacity but can work for several years due to its low coefficient of self-discharge.

The following are the primary technological aspects of the tiny battery:

  • 11.6 mm in diameter
  • 5.4 mm in height;
  • 2-gram weight (can vary by several tenths of a gram from different manufacturers).

AG13 Battery vs AG10 Battery

Is an AG10 button battery the same as an AG13 button battery? No, their diameters are the same, but AG10 is thinner (about 3.1 mm vs. about 5.4 mm for the AG13). As a result, the AG13 has somewhat more than double the capacity of the AG10.

If you're wondering which one you have, and AG10 is roughly the thickness of two US/Canadian pennies or Euro cents; an AG13 is roughly the thickness of three US quarters or Canadian toonies, slightly thicker than three Euro cents, or little less than the diameter of a pencil.

An AG10 battery may fit in a device meant for an AG13, but it will most likely not establish good contact. If it fits, it will work, but only for a short while. An AG13 will very certainly not fit in a device built for an AG10.

The IEC designation for the AG10 is SR1131 and for the AG13 is SR1154; the first two digits are the diameter in millimeters and the second two digits are the height in tenths of millimeters. Confusion ensues when the AG10/SR1131 is referred to as SR54 and the AG13/SR1154 is referred to as SR44. This could be the reason for your confusion: SR54 is not the same as SR1154.

These are silver oxide batteries (thus the "AG" suffix); alkaline batteries are also available. The alkaline equivalent of the AG10 is LR54 or LR1131; for the AG13, it is LR44 or LR1154. The "L" models are less expensive, but they don't last as long—you probably won't notice the difference.

If you live in the United States, you can usually get Duracell and Energizer versions of these batteries at your local drugstore. The Duracell 389/390 is the Duracell counterpart of the AG10 battery, and the Energizer equivalent is likewise 389; both are silver oxide batteries. Duracell's counterpart is 303/357 or 303/357/76 (silver oxide), while Energizer's equivalent is A76 (alkaline).

 AG13 vs.LR44 vs. A76

As previously stated, mercury-oxide batteries are no longer commercially available or have been phased out due to their dangerous mercury content.

When compared to alkaline batteries, zinc-air batteries have a lower voltage output (1.4 V vs. 1.5V). However, some battery types may store 600 or 700 mAh, making them excellent for devices with high power consumption, such as digital cameras and MP3 players.

Silver-oxide batteries are like a superior form of alkaline batteries because they have 1.55 volts instead of the standard 1.5, and their voltage remains consistent at roughly 12 when in operation. Smaller gadgets should be powered by silver-oxide batteries. Alkaline batteries are less expensive and more adaptable, but they lack the voltage required to power such gadgets. You're aware that silver-oxide batteries are more expensive than alkaline batteries, but the price difference is justified when you consider their features and performance. The cost difference between them is negligible in larger shipments.

Alkaline batteries are a great choice for everyday use and small electronic gadgets. They're inexpensive, dependable, and offer a reasonable capacity of 110-130 mAh, depending on your device's cut-off voltage.

AG13 (Eurobatt): Alkaline battery with 1.5V, 0.9V nominal, and cut-off voltages, with a capacity of 130 mAh.

LR44 (Murata): Alkaline battery having 1.5V, 0.9/1.2V nominal, and cut-off voltages, with a capacity of 130 mAh.

SR44 (Murata): Silver oxide battery with 1.55V nominal, 1.2V nominal, and cut-off voltages, with a capacity of 155 mAh.

357 (Energizer): Silver oxide battery having 1.55V, 1.2V nominal and cut-off voltages, and a capacity of 150 mAh.

4.1 The Similarities: Between LR44, AG13 and A76

The LR44, AG13, and A76 have significant similarities that allow them to be used interchangeably.

Battery size, chemistry, and voltage are all shared by the LR44, AG13, and A76 battery. Furthermore, none of these batteries is rechargeable.

Size: 11.6mm x 5.4mm (Diameter x Height)

The physical size is the most evident comparison. Any battery meant to be used in place of an LR44 should have a diameter of 11.6mm and a thickness of 5.4mm to meet international standards. The size is crucial, as even a minor difference means that the battery will not fit in many of the compact devices for which it is designed.

Chemistry: Alkaline

Alkaline is the most common chemistry for these three battery categories. The AG13 battery and A76 battery designations, on the other hand, can deviate from the standard because they are manufacturer's component numbers.

Energizer's AG13 type battery, for example, employs silver oxide chemistry. A silver oxide battery can live up to three times longer than an alkaline cell.

The disadvantage of silver oxide batteries is their high cost. They are more expensive than alkaline equivalents, however, depending on how the batteries are utilized, a balance can be reached.

Voltage: 1.5 – 1.55 Volts

When new, all kinds of this battery produce 1.5 or 1.55 volts. The important element here is how the voltage will decline when in use. Throughout its useful life, the voltage of a common alkaline battery will drop to roughly 1 volt. Silver oxide variants are more expensive and have more stable voltages over time, often maintaining at least 1.2 volts.


None of these batteries is rechargeable, and attempting to recharge them is risky.

4.2 The Differences: Between LR44, AG13 and A76

As previously demonstrated, the three battery types, LR44, AG13, and A76, are interchangeable. But are there any distinctions that might lead you to prefer one over the other?

LR44 vs. AG13 vs. A76: Similarities & Difference

Battery Capacity

The voltage will always be 1.55 volts, however, the capacity of the battery can fluctuate. The usual capacity of an LR44 battery is between 110 and 130 mAh.

This is determined by the chemistry employed and the quality of the components. Silver oxide batteries can yield between 150 and 200 mAh, allowing them to last longer. Purchasing a branded product over a generic item will usually result in a more powerful battery, but it will be more expensive.

You may have a preferred brand. Perhaps you've tried every brand and discovered one that lasts longer or performs better. Part numbers are assigned to objects by different manufacturers.

There are numerous AG13 battery producers in both Russia and abroad. Replace with an analog battery from any firm that has the same size and weight as the original but is made by a different manufacturer.

Duracell, Camelion, and Varta batteries are very efficient in terms of performance and durability. They can now be purchased in product marketplaces for 10 rubles.


According to customer reports, they last around 20% longer than others, or roughly four years. Miniature power supplies and additional companies should be considered:

  • Energizer
  • Renata
  • Minamoto
  • Robiton

Hearing Aid Battery 675 Batteries are installed in small items, and it is sometimes inconvenient to do so on their own, or power supplies are inadequately adjusted after installation. Special holders aid in the resolution of this issue. They can be added, although this raises the price slightly

 Important Considerations while Purchasing

The AG13 battery must be of the appropriate size. Even a one-millimeter oscillation will not allow it to be repaired. Size information can be discovered in the device's instruction manual or on an old battery.

In addition, consideration should be given to:

  • power and voltage;
  • voltage and capacitance
  • the holder's existence in the kit;
  • a set of temperature settings for operation
  • Important! The concern of employing small food sources is that they can be swallowed by children. The materials induce toxicity if they enter the esophagus. Children should not be given devices containing such batteries.

It is only possible to charge batteries.

8. Can you Replace an AG13 Battery with an LR6 Battery?

LR6 is an Alkaline call in the AA size.

AG13 Button Batteries are also known as 303, 357, LR44, L1154, A76...

An LR6 would have the necessary voltage and current capacity. and are far more durable.

However, because of significant physical size and shape variations, it would be difficult to engage the LR6 with contacts in a device using the button cell.

If you connect it successfully, it will work for a much longer period of time. The majority of items that use an AG13 size button cell do so to attain a modest size and profile. That, too, will be defeated.
