CR2032 Lithium Button Battery: 3V Coin Cell for Weight Scales and Remote Controls

This CR2032 battery is a lithium manganese button cell providing a standard 3-volt output, designed specifically for powering a broad spectrum of low-power consumer electronics. With a compact diameter of 20.0mm and a height of 3.2mm, it fits standard coin cell compartments found in devices from kitchen scales to car key fobs. The product description clearly states this is a second-class (B product) electronic component intended for low-power applications, and buyers should be aware that a small number of units may arrive with insufficient charge. Its practical value lies in its common form factor and stable voltage, serving as a direct replacement or power source for many household and office gadgets without the need for specialised batteries.

Features and Construction

The battery's design centres on providing reliable, low-level power with features aimed at maintaining integrity during use. It is built to meet the basic demands of devices that require a consistent 3V supply.

Material and Build

The CR2032 cell is a lithium manganese battery, a chemistry known for providing a high single-cell voltage and stable discharge characteristics suitable for intermittent-use devices. The outer casing is made from a steel sheet described as wear-resistant and high-temperature resistant. This construction, combined with stated anti-leakage technology, forms the primary physical barrier of the battery, aiming to contain the cell's contents securely within the common applications for which it is designed.

Size and Practical Fit

With precise dimensions of 20.0mm in diameter and 3.2mm in height, this battery conforms to the international CR2032 size standard. This makes it a direct fit for the battery holders in countless electronic products. The compact, flat coin shape allows it to be used in slim devices like remote controls, calculators, and digital thermometers, where space is at a premium and a reliable, flat power source is required.

Uses and Placement

The listed applications for this 3V button battery cover both everyday home items and more specialised electronic tools, highlighting its role as a general-purpose power source for simple circuits.

Event or Professional Use

In professional or event settings, these batteries can serve as reliable power for equipment like attendance machines, electronic flash products, or portable measurement tools such as tyre pressure gauges and blood glucose meters used in various contexts. Their stable voltage supports the accurate functioning of sensors and displays in these devices, which is crucial for obtaining consistent readings.

Everyday Home Use

Within the home, this battery is most commonly associated with powering remote controls for televisions (such as Mi TV), cars, and other entertainment systems. It is also frequently used in personal health devices like ear thermometers and body fat testers, kitchen appliances like electronic scales, and convenience items like digital watches, toys, and perpetual calendars. Its utility stems from providing long-term, low-maintenance power for devices that are used periodically.

Benefits and Buying Value

The value proposition of this battery is grounded in its compatibility, stated technical specifications, and cost-effective application for supported low-power devices.

Reuse and Low Maintenance

As a single-use, non-rechargeable primary cell, its maintenance is inherently low—simply replace it when depleted. The steel casing and anti-leakage design are intended to support safe operation throughout the battery's service life within the device, reducing the risk of damage to the equipment from battery leakage, a practical benefit for protecting your electronics.

Why Choose This Product

This product is specified as a solution for users who need a standard CR2032 form-factor battery for undemanding, low-power electronic devices and are aware of its classification as a second-class (B product) component. Its stated 3V output, 160mAh rated capacity, and 20.0 x 3.2mm dimensions provide concrete data for verifying compatibility with your device. The value comes from securing a functionally appropriate battery for a wide range of common applications, from weight scales to computer motherboards, based on these supported specifications.
