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

This CR2032 lithium manganese button battery provides a reliable 3-volt power source specifically engineered for low-power electronic devices. With a standard capacity of 160mAh and dimensions of 20mm by 3.2mm, it is the common cell type for a wide array of household and personal electronics. Key applications include weight scales, car remote key fobs, computer motherboard CMOS batteries, electronic dictionaries, and digital thermometers. It is important for buyers to note that this product is listed as a B-grade item, meaning it is a secondary product where a small number of cells in a batch may have insufficient charge. It is therefore recommended for cost-effective, low-demand scenarios where premium battery performance is not critical.

Features and Construction

The battery is built to common CR2032 specifications, ensuring compatibility with a vast range of device compartments. Its construction focuses on practical reliability for its intended use case.

Material and Build

The cell utilises lithium manganese dioxide chemistry, which delivers a stable nominal voltage of 3 volts. The casing incorporates a steel sheet that is described as wear-resistant and high-temperature resistant. Furthermore, the battery employs anti-leakage technology, a valuable feature for protecting sensitive electronic contacts in devices over time, especially during storage or in varying environmental conditions.

Size and Practical Fit

The physical specifications are precisely 20.0mm in diameter and 3.2mm in height. This is the universal standard for CR2032 batteries, ensuring it will fit correctly in devices designed for this cell type, from tiny car remote controls to larger electronic weight scales. The compact, button-cell format makes it easy to install and replace.

Uses and Placement

This battery's design suits a specific segment of the electronics market, focusing on devices with minimal power draw. Understanding its intended applications helps ensure it is used correctly.

Event or Professional Use

For professional or commercial settings, these batteries could serve as economical spares or bulk replacements for devices where continuous, premium-grade power is not essential. Examples might include backup batteries for attendance machines, spare cells for shared office peripherals, or for use in promotional electronic items where cost per unit is a significant factor.

Everyday Home Use

In the home, this battery is suited for powering a variety of common devices. This includes TV remote controls (such as for Xiaomi TVs), digital kitchen scales, body fat analysers, car tyre pressure monitors, electronic calendars (perpetual calendars), toys, and digital thermometers (like ear thermometers). Its versatility across these common items makes it a practical household staple.

Benefits and Buying Value

The value of this product lies in its specific application and packaging options, offering a practical solution for defined needs.

Reuse and Low Maintenance

As a disposable primary cell, its main benefit is a long shelf life and stable discharge, reducing the frequency of replacement in low-drain devices. The anti-leakage technology helps maintain device integrity, potentially extending the life of the electronic product itself by preventing corrosive damage from battery leakage.

Why Choose This Product

This battery is chosen for its cost-effectiveness in non-critical, low-power applications. It is available in flexible quantities, from a small card of 5 cells for immediate needs to a bulk box of 5000 for commercial replenishment. The clear labelling as a B-product manages expectations, informing buyers that while most cells will function, the batch may contain a minor percentage with reduced charge, making it ideal for users who prioritise budget over guaranteed peak performance in every single cell.
