CR2032 Lithium Button Battery 5-Pack for Weight Scales and Remote Controls

This product is a card of five CR2032 lithium manganese button batteries, designed as a basic power solution for a wide array of common, low-power electronic devices. With a standard voltage of 3V and a rated capacity of 160mAh, it provides the necessary energy for items ranging from car key fobs and computer motherboards to electronic scales and digital thermometers. It is important to note that this is classified as a B-product, or second-class, electronic component. This classification indicates that while the majority function correctly, a small proportion of units within a batch may have insufficient charge or be non-functional, a condition accepted by the purchaser. The battery employs anti-leakage technology and is built with materials including a wear-resistant steel sheet.

Features and Construction

This battery pack offers a straightforward specification tailored for replaceable power in consumer electronics. The key specifications are clearly defined, focusing on the electrical output and physical size required for device compatibility.

Material and Build

The battery utilises lithium manganese chemistry, which delivers a consistent 3-volt output ideal for the stable operation of digital circuits. Its construction incorporates a steel sheet described as wear-resistant and high-temperature resistant, contributing to the cell's physical integrity and its stated anti-leakage performance. This practical design aims to prevent electrolyte leakage that could damage sensitive electronic components.

Size and Practical Fit

Each individual CR2032 battery has precise dimensions of 20.0 millimetres in diameter and 3.2 millimetres in height. This is a standardised size for button cells, ensuring it fits the battery compartments of a vast number of pre-existing devices. The compact form factor makes it a ubiquitous choice for space-constrained electronics, from small remote controls to circuit boards.

Uses and Placement

The application range for this 3V button battery is extensive, covering both professional tools and everyday household items. Its primary role is to provide reliable, long-term power for devices with low current draw.

Event or Professional Use

In professional or dedicated device contexts, this battery type is commonly found in equipment like computer motherboards (for CMOS memory), electronic point-of-sale systems, attendance machines, and certain medical devices such as ear thermometers and blood glucose meters. Its stable discharge voltage is crucial for the accurate readings and data retention required in these applications.

Everyday Home Use

For daily household use, these batteries are frequently used in car and television remote controls, electronic kitchen scales and weight scales, digital perpetual calendars, children's toys, wristwatches, and electronic insect repellents. The wide applicability stems from the standardised size and voltage that match the design of countless consumer products.

Benefits and Buying Value

The value of this product lies in its function as an affordable, multi-purpose power source for essential devices. Understanding its grade and intended use is key to a satisfactory purchase.

Reuse and Low Maintenance

As a disposable primary cell, this battery is not designed for recharging. Its value is in its long shelf life and low self-discharge rate, allowing users to store spares. The anti-leakage technology is a key benefit for low maintenance, helping to protect device contacts from corrosion during the battery's lifespan and after it is depleted.

Why Choose This Product

This battery pack is chosen primarily for its cost-effectiveness and compatibility. It serves as a practical bulk purchase for users who need to power multiple low-demand devices and who accept the possibility of the occasional underperforming unit inherent to its B-grade status. It is explicitly recommended for the use of low-power products only, and customers seeking higher guaranteed quality are advised to consider alternative options.
