A76 Battery Overview

What are A76 batteries?

You often use A76 batteries in small electronic devices (such as electronic watches, calculators, and remote controls). These batteries are button cells. They are round and flat, fitting into the tight spaces inside devices. There are two main types of A76 batteries: alkaline and silver oxide. Silver oxide batteries are called SR44, while alkaline batteries are also called LR44. Both batteries have similar dimensions, approximately 11.6 mm in diameter and 5.4 mm in height. They are also lightweight, typically weighing between 1.8 and 2.28 grams.

Below is a brief introduction to the technical details of the SR44 and LR44 batteries:

Specification	Details
Battery Type	Alkaline (LR44) or Silver Oxide (SR44)
Nominal Voltage	1.5 V (Alkaline), 1.55 V (Silver Oxide)
Capacity	150-200 mAh (Alkaline), 150-170 mAh (Silver Oxide)
Size (Diameter x Height)	11.6 mm x 5.4 mm
Weight	1.8 to 2.28 grams
Chemistry	Alkaline manganese dioxide, Silver Oxide
Temperature Range	-10°C to 60°C (14°F to 140°F)
Shelf Life	3-5 years (Alkaline), 5-10 years (Silver Oxide)
Equivalent Models	LR154, SR1154，AG13, 357, SR44

From the above data, we can see that the a76 battery has a stable voltage and a long service life. The chemical characteristics inside the a76 battery enable it to continue to provide power for months or even years.

LR44

The LR44 battery is a more common A76 equivalent. It uses alkaline button cell chemistry, meaning its core is zinc and manganese dioxide. The nominal voltage of an LR44 battery is 1.5 volts. This voltage slowly decreases with use. LR44 batteries are commonly found in electronic remote controls, calculators, and watches. They are less expensive than silver oxide batteries.
LR44 batteries are suitable for devices that don't require a stable voltage. If your device requires long-term power or requires a stable voltage, you may want to use a silver oxide battery. LR44 batteries typically last from several months to over a year, depending on how often you use the device. For low-power devices where cost is a priority, LR44 batteries should be used.

Feature	SR44 Battery (Silver Oxide)	LR44 Battery (Alkaline)
Chemistry	Silver Oxide and Zinc	Zinc and Manganese Dioxide (Alkaline)
Nominal Voltage	Approximately 1.55 volts	1.5 volts
Voltage Behavior	Voltage remains stable throughout discharge	Voltage drops significantly during discharge
Capacity	Typically 150-200 mAh	Typically 110-130 mAh
Shelf Life	5-10 years; less risk of leakage	3-5 years; moderate risk of leakage over time
Performance	Provides stable voltage and longer lifespan;  better for devices needing consistent power	Suitable for low to moderate power, cost-effective;  performance declines faster under continuous use

NOTE: LR44 batteries are physically interchangeable with 357, AG13, and SR44, but the chemistry will affect their performance.

357

357 batteries stand out from A76 batteries because they typically use a silver oxide chemistry. This results in a higher and more stable voltage of 1.55 volts. 357 batteries maintain this voltage until they are depleted. This makes them ideal for devices that require a reliable power source, such as watches, calculators, and small medical devices.
357 batteries last longer than LR44 or AG13 batteries, especially in high-powered devices. You can often use 357 batteries instead of LR44 or AG13 batteries. However, 357 batteries are more expensive. If your device requires a stable voltage and a longer battery life, 357 batteries are a better choice.

Characteristic	LR44 / AG13 Battery (Alkaline)	357 Battery (Silver Oxide)
Chemistry	Alkaline	Silver oxide
Capacity	Generally lower capacity	Higher capacity (~150-190 mAh)
Voltage Stability	Voltage drops steadily during use	Relatively constant voltage (~1.55V)
Lifespan	Shorter lifespan, especially in high-drain devices	30% to 100% longer lifespan
Suitability	Less suitable for high-drain devices  due to voltage drop and lower capacity	Ideal for high-drain and precision devices

SR44
The SR44 battery is another silver oxide battery equivalent to the A76 battery. It has a nominal voltage of 1.55 volts and uses a silver oxide chemistry. The SR44 battery offers stable voltage, which is crucial for precision equipment such as watches and medical instruments.
SR44 batteries last longer than LR44 and AG13 batteries and have a lower risk of leakage. SR44 batteries are more expensive, but they offer better performance in devices that require a stable power supply. They should be used in devices that require the highest accuracy and reliability.

Feature	SR44 (Silver Oxide)	LR44 (Alkaline)
Voltage	1.55 V	1.5 V
Chemistry	Silver oxide	Alkaline Zinc Manganese
Voltage Stability	Stable, flat discharge profile	Voltage drops over time
Energy Density	Higher energy density	Lower energy density
Typical Use	Watches, calculators, precision devices	General electronics, toys, thermometers
Impact on Precision Use	Consistent voltage ensures accuracy	Voltage fluctuations can affect device performance

AG13
The AG13 battery is another commonly used equivalent to the A76 battery. It is nearly identical to the LR44 battery. Both utilize an alkaline button cell chemistry and have a nominal voltage of 1.5 volts. AG13 batteries also use zinc and manganese dioxide. You'll see AG13 batteries in watches, calculators, and other applications.
The capacity of an AG13 battery is approximately 110-130 mAh.
The voltage decreases over time, just like an LR44 battery.
Most AG13 batteries are alkaline, but some silver oxide versions also exist.
AG13, LR44, and A76 batteries are often labeled as equivalent.
AG13 batteries can replace LR44 or A76 batteries. The main difference is the labeling. Performance and lifespan are nearly identical. If you need a longer-lasting battery, you should opt for a silver oxide battery like the 357 or SR44.

A76 Interchangeability and Key Differences

LR44, AG13, 357, and SR44 batteries are all the same size and generally interchangeable. However, it's important to consider that different chemistries and voltages may affect how your device operates.
LR44 and AG13 are 1.5V alkaline button batteries, and their voltage drops with use.

357 and SR44 are 1.55V silver oxide batteries, which offer a stable voltage and a longer lifespan.
Devices requiring stable power, such as watches or medical tools, perform better with silver oxide batteries.
Toys and calculators can use LR44 or AG13 batteries, as they are more affordable.

Tip: The appropriate A76 battery for your electronic device depends on the environment it's used in. Silver oxide batteries are more expensive, but offer a longer lifespan and better performance.
