CR2032 3V Lithium Manganese Button Battery for Weight Scales and Low-Power Electronics

This CR2032 lithium manganese button battery offers a practical power source for a wide range of household and consumer electronic devices where premium battery performance is not the primary requirement. As a B product or second-class product, it provides a budget-friendly option for powering items like electronic scales, car remote controls, computer motherboards, and various measurement devices. With a standard voltage of 3V and a rated capacity of 160mAh, this coin cell battery delivers the necessary power for basic electronic functions. The battery employs anti-leakage technology and features a steel sheet construction designed to be wear-resistant and tolerant of higher temperatures, making it suitable for general use in controlled environments.

Features and Construction

The CR2032 battery is built to the standard coin cell specifications expected for this common battery size, with particular attention to basic protective features that prevent leakage and provide some durability.

Material and Build

Constructed as a lithium manganese battery, this cell provides the characteristic high single-cell voltage and stable discharge profile associated with this chemistry. The steel sheet casing is treated to be wear-resistant and able to withstand elevated temperatures, while anti-leakage technology helps maintain integrity during storage and use. It is important to note that as a B product, manufacturing tolerances may vary slightly, and a small proportion of units might have insufficient or no charge upon delivery.

Size and Practical Fit

With dimensions of 20.0mm in diameter and 3.2mm in height, this battery conforms precisely to the CR2032 form factor, ensuring compatibility with battery compartments designed for this ubiquitous size. The standardised measurements mean it can directly replace other CR2032 batteries in devices such as weight scales, remote controls, electronic thermometers, and computer motherboards without modification or adapter requirements.

Uses and Placement

The battery's specifications make it suitable for numerous common electronic applications, particularly those with modest power requirements that don't demand premium-grade battery performance.

Event or Professional Use

For trade professionals, event organisers, or bulk users who require large quantities of batteries for non-critical applications, this B product offers considerable cost savings. The availability in bulk packaging options—5 capsules per card, 100 per box, or 5000 per piece—makes it practical for stocking maintenance kits, supplying temporary installations, or powering demonstration units where battery performance is monitored and can be easily replaced if necessary.

Everyday Home Use

In domestic settings, this battery serves numerous common devices found in households. Its applications include car remote controls for keyless entry systems, computer motherboards for CMOS memory backup, electronic dictionaries, television remotes (including Xiaomi TV), ear thermometers, blood glucose meters, body fat testers, car tyre pressure gauges, electronic scales, weight scales, perpetual calendars, toys, watches, attendance machines, electronic mosquito repellents, and camera flash units. For devices where battery failure is inconvenient but not catastrophic, this battery provides adequate performance.

Benefits and Buying Value

Choosing this battery involves balancing performance expectations with budgetary considerations, making it suitable for specific user scenarios where cost reduction is prioritized.

Reuse and Low Maintenance

The battery's stable discharge voltage and relatively small self-discharge rate mean it can maintain charge during storage for reasonable periods when not in use. For devices that are used intermittently—such as seasonal items, backup equipment, or occasionally used measurement tools—this characteristic helps ensure the battery remains viable when needed. The anti-leakage technology provides additional protection for devices during periods of non-use, reducing the risk of damage to battery compartments.

Why Choose This Product

This battery is selected primarily for economic reasons in applications where premium battery performance is unnecessary. The B product designation indicates it may have minor cosmetic imperfections or, in some cases, reduced initial charge, but it remains functional for many basic electronic devices. It represents a practical choice for users who understand these limitations and are prepared to test batteries upon receipt, making it ideal for cost-conscious consumers, bulk purchasers, or those powering non-critical devices where occasional battery replacement is acceptable.
