Among these, the AG3 battery has acquired great popularity due to being small-sized, highly cost-effective, and compatible with most devices. Small batteries are essential for powering devices that would be impractical to function with larger, bulkier power sources. The AG3 battery is one such example that has become ubiquitous in powering everyday gadgets. Understanding its specifications, features, and equivalents is essential for ensuring optimal device performance and longevity. In this article, we are going to dive into the parameters and features of the AG3 battery, its equivalents, purchasing options, and practical tips on how to maximize its lifespan.

AG3 Battery Parameters & Features

The AG3 battery is one of the alkaline button cell batteries that are very common in small electronic devices. It is compact, lightweight, and suitable for use in calculators, watches, small toys, hearing aids, and remote controls. AG3 is a very reliable and has a long shelf life; hence it is very appropriate for low-power devices.

Key Parameters:

• Chemical System: Alkaline Manganese Dioxide

• Nominal Voltage: 1.5V

• Diameter: About 7.9mm

• Height: About 3.6mm

• Capacity: 25-35mAh, depending on the manufacturer

• Weight: Approximately 0.6 grams

• Shelf Life: Usually 3-5 years, depending on storage conditions

Features:

• Compact Design: Suitable for small and light electronic devices that require limited space.

• Economical: AG3 batteries are inexpensive and can be found easily, both by the consumer and by manufacturers.

• Low Self-Discharge: The battery does not lose its charge as much when stored and will be ready to use when required.

• Environmental Impact: Although the AG3 battery is small and energy-efficient, it does contain small amounts of toxic substances like mercury and cadmium. Proper disposal or recycling is necessary to minimize environmental impact.

• The AG3 battery is compact, low in cost, and reliable; thus, it is appropriate for a wide range of applications. Its affordability also ensures that the replacement of these batteries is not a strain on your budget; thus, it is favoured by many consumers worldwide.

• Chemistry of AG3 Batteries: The AG3 battery uses an alkaline manganese dioxide chemical system, one of the most popular used in many small batteries. The system works by combining zinc and manganese dioxide (MnO2) to generate electricity. In most cases, the battery's anode is composed of zinc, while the cathode is made up of manganese dioxide. In the presence of an electrolyte, these two substances react with each other, producing electrical energy.

In comparison to other types, such as lithium or zinc-carbon, alkaline batteries such as the one found in the AG3 offer higher energy density and shelf lives. An alkaline battery undergoes a stable chemical reaction inside which is why the AG3 can be stored for multiple years if properly maintained.

Applications of AG3 Batteries

AG3 batteries are used in several applications. They are applied where devices need to run on low power for a long time. The following are examples of such applications.

• Wristwatches: Analog and digital wristwatches often require AG3 as it has the size to fit small applications, providing steady output power for long periods of time.

• Calculators: Small scientific and basic calculators often use AG3 batteries due to their low drain and long shelf life.

• Toys: Many small toys and novelty items, particularly those that use minimal electronics, are powered by AG3 batteries.

• Hearing Aids: Some models of hearing aids rely on AG3 batteries to provide consistent, reliable power without adding bulk.

• Remote Controls: Remote controls for devices such as TVs, cameras, and home automation systems often use AG3 batteries because of their low power requirements.

• Medical Devices: Small medical devices, such as thermometers and glucose meters, may also use AG3 batteries to maintain compactness and portability.

• Because of this versatility, AG3 batteries are a go-to power source for many low-power devices that are part of everyday life..

AG3 Battery Equivalents 

The AG3 battery has other names and equivalents based on the manufacturer or region. Knowing which ones are compatible will be important in finding a replacement. Here is a more detailed list of AG3 battery equivalents:

Other Names:

• LR41: This is probably the most known alternative name for the AG3 battery.

• 192: Another common name for AG3 in some regions.

• L736: A bit less popular designation but it's still present in some brand's list.

• LR736: The IEC equivalent for AG3 battery

• G3A: One of those designations, sometimes is present on package

​

IEC Standard Designation:

1. LR736: This IEC designation has for AG3 batteries

2. Alternatives in Silver Oxide

3. SR41: With a bit higher voltage - 1.55V, compared to AG3, offers longer life cycle.

4. SR736: Another silver oxide substitute that offers the same advantages as the SR41.

Silver oxide substitutes like SR41 or SR736 can be used to deliver improved performance and increased battery life. These are great for high-drain applications where steady power is critical. Silver oxide batteries usually cost more than alkaline, so determine if it's worth it to have longer life.

Compatibility Factors:

While silver oxide is compatible with most devices, it is highly important to ensure that one checks on the voltage among other specifications before replacing the AG3 with one. Some devices are designed particularly for 1.5V alkaline batteries; therefore, it may not work very well with silver oxide's 1.55V alternative. Always be sure to refer to the manual for your device prior to getting a replacement.
