Guide to Choose 371 Battery & Equivalents

The 371 battery, also known as the SR920SW battery (international standard model), has a small button-like appearance. This design allows the 371 battery to be easily embedded in a variety of small electronic devices, such as watches, smart phones, tablets, and portable medical devices. It uses advanced battery chemistry and manufacturing processes to ensure stable performance during cyclic charging and discharging. In addition, it also has excellent safety performance, which can effectively prevent short circuit, overcharge, over-discharge and other safety hazards, to provide users with a more secure experience.

Basic overview of 371 battery

The 371 battery belongs to a type of alkaline battery. Alkaline batteries are known for their relatively high energy density and long service life. Compared to some traditional carbon batteries, 371 alkaline batteries can provide a longer power supply under the same conditions of use. The chemical structure of the battery allows it to release electricity more stably during discharge, reducing the impact of voltage fluctuations on the device.

The positive and negative terminals of the battery are located at each end of the battery, and the positive terminal usually has a raised circular point for contact with the battery compartment contacts in the device. The negative electrode is located at the bottom of the battery and forms contact with the underside of the device's battery compartment. This design ensures that the battery can provide power to the device steadily and reliably.

In addition, the appearance of the 371 battery may also vary from manufacturer to manufacturer, such as the color of the housing, identification information, and so on. But in any case, its basic button-like design and positive and negative electrode layout are consistent.

The size of the 371 battery is one of its important technical specifications and is crucial to ensure that the battery can be properly installed into the device. The following is the specific size information of the 371 battery:

Diameter: 9.5 mm

Thickness: 2.05 mm (there are also data showing 2.1 mm, which may be due to small differences in the production process of different manufacturers)

This size information ensures that the 371 battery can be adapted to a variety of small electronic devices that use the button battery as a power source. At the same time, because the size standard of button batteries is relatively uniform, 371 batteries can also be used as a substitute for other models of button batteries, such as AG6, 171, etc.

Performance and advantages of 371 battery

The nominal voltage of a 371 battery is usually 1.5V, which is within the operating voltage range of many small electronic devices. Over the entire life of the device, the 371 battery is able to maintain an output voltage close to 1.5V for a considerable amount of time. For example, when used in a small electronic clock, it can stably supply power to the clock's circuit, ensuring that the clock accurately travels. Even with the gradual consumption of battery power, the process of voltage drop is relatively slow, which means the device can still maintain basic functions in the state of low power.

Besides, the total capacity of the 371 battery can meet the daily use needs of many small devices. Its capacity is determined by a series of chemical and physical parameters. In practical applications, for devices like small calculators, a single 371 battery can last for months or even years. This is because the power consumption of devices such as calculators is relatively low, and the 371 battery can continuously and steadily release power in a state of low power consumption. For some slightly more power-consuming devices, such as small LED flashlights, the 371 battery will be relatively short, but it can still provide enough power to meet the needs of temporary emergency use.

Moreover, 371 batteries have a low self-discharge rate. Self-discharge refers to the loss of the battery's own power when it is not connected to any external circuit. The low self-discharge rate means that the 371 battery holds its charge well during storage. For example, if a new 371 battery is placed in a device but not used for a long time, after several months, it will still be able to retain a significant portion of its charge. This is very important for devices that are not used often but need to be on standby, such as small alarms for emergency use.

And the 371 battery has a number of advantages which make it become more and more popular on the electronic market.

Practical application of 371 battery

In the field of consumer electronics, 371 batteries have a wide range of applications. The first is in a variety of small remote controls, whether it is a TV remote control, air conditioning remote control or other smart home device remote control, 371 batteries are a common source of energy. Its small size can adapt to the compact design of the remote control, and its power is enough to meet the frequent button operation needs of the remote control. Secondly, in some small electronic toys, 371 batteries also play an important role. For example, some simple Tamagotchi toys or small musical toys, 371 batteries can provide enough electricity for these toys, so that children can play happily.

In the field of medical devices, 371 batteries also have their use. For example, some small portable medical monitoring equipment, such as blood glucose meter, blood pressure meter, etc. These devices need to be easily used in the patient's home or on the go, and the small size and stable power supply of the 371 battery allow these medical devices to work anywhere and anytime. For some patients who need to monitor their health indicators regularly, the reliability of the 371 battery ensures that they can accurately access their health data.

In the field of industrial and office equipment, 371 batteries also have certain applications. For example, some small office equipment sensors, such as paper margin sensors, 371 batteries can provide power for these sensors to ensure that office equipment can timely feedback paper use and other information. In industry, some small handheld detection equipment, such as simple electronic multimeters, can also use 371 batteries as a power source, which is convenient for workers to carry out rapid measurement and detection work in the field.
