AG10 Battery Equivalents and Guide

AG10 batteries are small, non-rechargeable button/coin batteries. AG10 Batteries power devices like watch batteries, calculators, toys, and car keys. Equivalent AG10 batteries include LR54, LR1130, L1131, and G10. Many brands sell LR1130/AG10 batteries, but many label them differently, so users wonder which battery is an LR1130/AG10.

The most common labels for coin or button cells are AG10 and LR1130, with dimensions of 11.6 mm by 3.1 mm (0.567 x 0.1220 inches). 

As a result, AG10/LR1130 batteries are commonly found in small electronic devices that only require a small amount of power. The price of an alkaline AG10 is very cost effective.


Features and Specifications of AG10 Batteries

A 1.5V/0.9V/45-70mAh alkaline battery, the AG10/LR1130 has a nominal voltage of 1.5V, a cutoff voltage of 0.9V, and a little capacity of 45-70mAh. A battery’s actual capacity varies with its age, operating temperature, and current drain. Due to its low self-discharge rate, a battery stored at room temperature has a shelf life of 2-3 years, sometimes slightly longer.

Most alkaline 11.6 x 3.1 mm batteries are labeled with “LR1130”, although other labels are not uncommon, including “AG10,” “LR1131,” “LR54,” and similar. The 11.6 x 3.1 mm alkaline batteries are a reliable and inexpensive power source for small devices and toys and can be easily found in hardware and office supply stores and on the Internet.

Non-rechargeable silver-oxide batteries measure 11.6 x 3.1 mm and offer similar performance to alkaline batteries. Silver Oxide batteries come in a variety of sizes and shapes. A common one with 11.6 x 3.1 mm is labeled SR1130, although other labels are also used, including SR1130W, SR1130SW, SR1130PW, SR1131, SR54, 189, 387, 389, 390, etc.

One must also check other features since some manufacturers use labels for alkaline and silver-oxide batteries interchangeably. With a nominal voltage of 1.55 volts, a cutoff voltage of 1.2 volts, and a capacity of 65-90 mAh, the SR1130 battery offers a nominal voltage and power. It is important to note that actual capacity is affected by several factors, such as the battery type, the type of battery, its age, and other factors.

Occasionally, silver-oxide batteries are manufactured with a “low-drain” and a “high-drain” capacity, but more recently, they are sold as “general purpose” or “multi-drain” batteries. Battery SR1130 Silver Oxide has a shelf life of three to five years, sometimes even longer. It has a constant output voltage and is more powerful than alkaline LR1130 batteries. There is a slight difference in price between silver-oxide SR1130 and LR1130 batteries.


A guide to the AG10, 1.5V alkaline button battery.

The AG10 Battery Is Not Rechargeable

It is a primary alkaline cell with non-rechargeable chemistry. The two electrodes of the cell: zinc and manganese dioxide (MnO2), work together to generate the current. A metal salt known as potassium hydroxide makes up the electrolyte.  

Is an AG10 battery rechargeable? 

Chemical reactions are based on science. For example, chemical reactions in a battery must be reversible for it to be recharged. In other words, the reaction product must be decomposed into the same substances from which it came. In the reverse reaction, A and B must be broken down to produce C. 

A battery of this type cannot be reversed until it has reached 40% discharge due to the zinc/manganese dioxide reaction, which creates the cell’s chemical energy. It becomes impossible to reverse the reaction after the first 40%. Hydrogen ions (H+) form when Manganese oxide (MnO2) reacts with water, resulting in groutite (MnOOH), a non-reversible compound.  Even after removing the hydrogen ions, groutite cannot be broken down into MnO2, so the alkaline battery cannot be charged again. The cells are in danger of exploding if you attempt to recharge them due to all the gas accumulating inside the seal. 


The AG10 Battery Is Stable

An AG10 battery has a nominal voltage of 1.5 volts, and it discharges at a continuous rate with high cutoff characteristics. During discharge, the battery exhibits:

  • An output voltage of roughly 1.1 to 1.3 volts when closed-circuit loaded.
  • It has a cutoff voltage range of about 0.8 to 0.9 volts.
  • In addition, the batteries are 70mAh, which means they can supply 70 milliamperes of power for one hour. 

Your small gadgets will have enough power to last a long time on the charge. Generally, these small gadgets have a power capacity of 1–5 milliamperes, so 70mAh will usually last a while. 

A device’s battery life will be determined by the amount of power it draws, along with the temperature at which it operates. 

Note: Battery AG10 alkaline button cells can operate at temperatures ranging from -10 to 60 degrees celsius. Temperatures between 21 and 22 degrees celsius, however, are ideal for a longer lifespan. 


AG10 battery button cells last for a long time.

Electrolyte potassium hydroxide is not involved in the reaction. Therefore, it can maintain a constant power output for a longer period since the battery remains unused. The AG10 alkaline button batteries have a slow self-discharge rate as well. In storage, they can last as long as three years at the right temperature. When you use them afterward, they’ll still provide the same amount of power. 


Temperature: These batteries should be stored between 10 and 25 degrees Celsius. When stored at a temperature over 30 degrees Celsius, chemical reactions are interfered with, damaging the casing and causing leaks.

AG10: Portable and Small batteries

These small, disc-shaped alkaline button batteries are very thin and have an unusual shape. Therefore, they are also referred to as “button” batteries. One gram weighs roughly 11.6 mm by 3.1 mm and measures 11.6 mm by 3.1 mm. Small in size and light in weight, they are ideal for small devices, such as watches, calculators, and toys.  Because these cells weigh so little, they won’t affect the weight of a device if they are used in a series. Furthermore, they are lightweight and easily portable, making them ideal for travel or outdoor activities. 

Children under three years old should be cautious when handling alkaline button cell batteries. It is so important that you keep those you haven’t used in their original blister packs. Make sure young children can’t get to them.  Double-check all toys’ battery compartment screws to ensure the seal is tight and secure. LR1130 and SR1130 batteries are readily available in the market with similar or perhaps even better specifications.


AG10 Zinc-Air PR43 battery replacements with 11.6 x 3.1 mm

With zinc-air batteries, the electrolyte is moist/wet, and oxygen is drawn from the air. As a result, zinc Air batteries operate at a slightly lower voltage (*1.4 volts), have a more stable output, and generally have a greater capacity than alkaline batteries. The battery dies, though, when the electrolyte dries, even if the battery is not fully discharged.

Thus, zinc-air batteries are used for devices that are used daily and require high-capacity batteries, like hearing aid devices and similar. It is very unusual to find a zinc-air battery with dimensions of 11.6 x 3.1 mm. There are zinc-air batteries in the nearby area, which are/were labeled as PR43, 7001Z, AC41E, and similar. However, these batteries are being phased out.

Hearing aid batteries are commonly referred to as 675 batteries, Blue tabs, ZA675, PR44, 7003ZD and similar. While 675 batteries and LR1130/SR1130 batteries are very similar in diameter and voltage, these batteries are not interchangeable because of the difference in height, internal resistance, and similar factors.


Battery Safety Issues with the LR1130/SR1130

Small, shiny objects such as LR1130/SR1130 batteries may attract children’s and pets’ attention. While most modern batteries do not contain lead, mercury, cadmium, and other heavy metals, they can still cause electrolytic reactions and burns to the body that can cause death if swallowed.  You should contact the nearest emergency center (or veterinarian) immediately if an LR1130/SR1130 or similar battery is swallowed. Explain to them what has happened, and follow their instructions. These factors have led to the packaging of coin/button cell batteries in child- or pet-safe packages.

Dispose of all batteries safely, especially button batteries that can be found by children.


Final Words:

You should purchase cheap, reputable brands that sell LR1130/AG10 batteries that have already been tried and tested by thousands of users if  you need a non-rechargeable 11.6 x 3.1 mm coin-cell battery.

SR1130 batteries are recommended for devices that need a higher output voltage, greater capacity, and longer shelf life. Don’t let pets or children play with these (or any) batteries!
