During its more than 150-year history, the battery or galvanic cell has not undergone significant changes. This is especially evident in comparison with the development of gadgets that work with it.
The external characteristics and reagents have changed depending on the application. The round AG13 batteries are called pills or buttons because of the similarity in shape.

AG13 Battery Specifications
These energy storage batteries are manganese-zinc. The installed chemical element, which acts as an energy generator, is manganese zinc. A relatively low-rated capacity characterizes this type, but it can work for several years with a low self-discharge rate.
The main technical characteristics of the miniature form battery are as follows:
- Diameter – 11.6 millimeters;
- Height – 5.4 millimeters;
- Weight – 2 grams (may vary by a few tenths of a gram with different manufacturers).
The nominal capacity of the battery is 110 mAh. However, some manufacturers supply products with a capacity of up to 190 mAh. The rated voltage is 1.55 volts.
The batteries of this type are distinguished by their ability to operate over a wide temperature range. They are effective at temperatures from +28.4 to +158 degrees Fahrenheit (from -2 to +70 degrees Celsius).
This is a helpful quality because they are installed on various equipment. As a result of overheating inside the device, temperature readings can be high, and this will not spoil the AG13 battery.

Where is the AG13 Battery Used?
The AG13 miniature power supply is mainly used for hearing aids. But the scope of application is not limited to this.
Sometimes they can be found in small wristwatches, miniature remote controls that are rarely used, calculators, and other equipment.
AG13 Advantages and Disadvantages
Alkaline batteries, to which the AG13 belongs, win in several ways, but they also have disadvantages.
Pros
- The storage period without loss of charge starts from 3 and can reach 7 years. Self-discharge is not affected by either negative or positive temperatures. In either case, it remains low.
- The capacity is 3-5 times higher. The advantage is seen in cameras and camcorders. A camera with flash is provided with energy on a salt source for 10 minutes, on an alkaline source for 100 minutes.
- The output of a stable discharge at low temperatures expands the possibilities of outdoor use in all weathers.
Cons
- High internal resistance does not allow their use in devices with high power requirements for initial start-up and maintenance.
- Significant weight compared to other sources, such as lithium sources—aggregate of chemicals and metal housing, susceptible to corrosion.
- Long-term storage in the compartment of an inoperative unit is dangerous for reagent leakage due to casing corrosion.
- Careful disposal is required so as not to contaminate the environment. Special treatment of the spent material is unnecessary, but given the number of devices used by mankind, the problem grows to enormous proportions.
If you compare with lithium, manganese-alkali are inferior in basic parameters, but the price is not comparable.
Note: The duration does not always correspond to the stated validity period. It depends on the intensity of the workload, temperature fluctuations, storage time before starting work.
AG13 Battery Equivalents
Analogs of the AG13 push-button battery on the modern equipment market are many. The main analogs are:
- LR44;
- L1154;
- V13GA;
- RW82;
- 303 357;
- V357;
- SR44.
Batteries marked 157, G13A, D357, SP357, SR44W, G13, PX76, 675, 1166A, A76, PX76A, A76-1, V13GA, GP76A, SR44SW, GPA76 are also available. Most are alkaline.
These batteries are the same size, but the specifications may be slightly different. The new power supply should be selected based on the specifications of the previous battery. It is best to take either the same technical specifications or slightly larger.
Popular Manufacturers and Their Features
AG13 batteries are available from established companies as well as from lesser-advertised companies. For the right choice, it is better to read the information on the package. It does not hurt to consult a retailer because the labeling differs from manufacturer to manufacturer.
- Energizer – The company that pioneered the industrial-scale production of dry cells for telephones.
- Renata – The Swiss company specializes in button cells for watches.
- Sony – The Japanese corporation was founded in 1946, based in Tokyo but operated worldwide.
- Varta – A world-renowned German brand. In the production of portable and stationary power sources.
- Seiko – Founded in 1881, a Japanese company producing watches, jewelry, precision instruments.
- Citizen – Japanese company producing watches, electronics, founded in 1918.
Many well-known brands are on everyone’s lips, and you can buy their products in any supermarket. But is it worth it to pay the companies’ advertising costs, or is it better to buy a product from an unknown company that owns the same technology? That is the question.
What to Pay Attention to Before Buying AG13 Battery?
Before buying, determine the technical characteristics: voltage, charge capacity, dimensions. Any powerful power supply will not be suitable if it is a millimeter wider or narrower than the receiving place. Parameters of work should be at the same level or higher.
You can ignore the rating of the manufacturer. The quality does not depend on the name, only the price. Practice shows that cell life in Duracell, Maxel, or Seiko is similar.
Rules of Operation and Disposal
Despite the deceptive ease of use, manufacturers recommend following certain rules.
- Do not heat, do not leave in the sun, keep away from heaters, and open flame.
- Familiarize yourself with the instructions of the device before you start.
- Observe the polarity of the contacts.
- Remove the batteries from the battery compartment if the device is stored for a long time.
- Store in a dry place away from metal objects.
- In children’s toys, tablets must be secured with a special holder that prevents access.
Note: Small batteries should not be available to children! Once in the child’s body, they can lead to poisoning, internal tissue burns, bleeding!
Please do not rush to throw them away with the garbage, but put them in a separate container. Please take it to a collection point when you have collected a certain amount. It doesn’t matter if you get money for it or not. The important thing is that you keep our common home clean. Recycled materials can be used as raw materials for recycling.
There are special collection points for recycling power supplies. Supermarkets, environmental organizations, and city and town municipalities collect the materials.
