CR2032 Lithium Manganese Button Battery for Weight Scales, Electronic Devices and Remote Controls

This CR2032 lithium manganese button battery is a 3V power cell designed for a wide range of common low-power electronic devices. Its primary applications include weight scales, electronic scales, car remote controls, computer motherboards, and various household electronics like electronic dictionaries and perpetual calendars. As a B-product (second-class electronics), it offers a cost-effective power solution for users who accept that a small portion of the batteries may have insufficient or no charge. The battery employs anti-leakage technology and features a steel sheet described as wear-resistant and high-temperature resistant. It is supplied in a standard size of 20mm in diameter and 3.2mm in height, matching the common CR2032 form factor.

Features and Construction

The battery is constructed as a lithium manganese button cell, providing specific electrical characteristics suitable for intermittent or low-drain devices.

Material and Build

This battery uses lithium manganese chemistry, which delivers a nominal voltage of 3 volts. The construction includes a steel sheet that is noted for being wear-resistant and resistant to high temperatures, contributing to the battery's physical robustness. The manufacturer specifies the use of anti-leakage technology, which aims to improve reliability and reduce the risk of electrolyte leakage that could damage the host device.

Size and Practical Fit

The physical dimensions are precisely 20.0mm in diameter and 3.2mm in height. This is the standard size for a CR2032 battery, ensuring compatibility with a vast array of electronic products designed to accept this common button cell format. The compact size makes it suitable for small, portable devices where space is limited.

Uses and Placement

The battery's 3V output and capacity are intended for low-power applications, as explicitly stated by the supplier. It is not recommended for high-drain devices.

Event or Professional Use

In professional or commercial settings, this battery can power devices like attendance machines, electronic scales used in retail or logistics, and car tyre pressure gauges. Its stable discharge voltage and small self-discharge rate are beneficial for equipment that may sit idle for periods between uses.

Everyday Home Use

For everyday household purposes, it is commonly used in TV remotes (such as for Xiaomi TVs), ear thermometers, blood glucose meters, body fat testers, toys, watches, electronic mosquito repellers, and electronic flash products. Its wide application range covers many common consumer electronics found in the home.

Benefits and Buying Value

The primary value proposition is providing a functional 3V button cell at a lower cost point, acknowledging its status as a B-product with potential variability.

Reuse and Low Maintenance

The battery is a single-use, non-rechargeable cell. Its value in maintenance reduction comes from its long shelf life and low self-discharge, meaning spare batteries can be stored for future use without significant charge loss. The anti-leakage technology is a practical feature aimed at preserving the device it powers.

Why Choose This Product

This product is chosen for its specific suitability for low-power devices and its cost-effectiveness. The clear labelling as a B-product manages expectations regarding consistent initial charge levels. It is an appropriate choice for users who require standard CR2032 batteries for non-critical applications and are prioritising value over guaranteed 100% initial performance from every individual cell.
