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

This CR2032 lithium manganese button battery is designed to deliver 3 volts of power to a broad spectrum of everyday electronic devices. With a standard diameter of 20mm and a height of 3.2mm, it fits a vast array of common gadgets found in homes and offices. It provides a rated capacity of 160mAh and utilises specific construction features aimed at reliable performance for its intended use cases. It is important for buyers to understand that this product is classified as a B product, indicating it is a second-class electronic component where a minor portion may exhibit insufficient charge.

Features and Construction

The battery is built to meet the basic power requirements of numerous consumer electronics. Its specifications are geared towards providing a stable voltage source where high current draw is not a primary concern.

Material and Build

The battery employs a lithium manganese chemical system, which delivers a nominal voltage of 3V. The cell is housed within a steel sheet casing described as wear-resistant and high-temperature-resistant. This construction contributes to the product's noted anti-leakage characteristics, helping to maintain integrity during use and storage under normal conditions.

Size and Practical Fit

The physical dimensions are precisely 20mm in diameter and 3.2mm in height, conforming to the standard CR2032 form factor. This size ensures compatibility with battery compartments in devices like car key fobs, computer motherboards, electronic scales, and remote controls. The compact, button-cell design makes it a ubiquitous power solution for space-constrained applications.

Uses and Placement

This battery's 3V output and specific form factor make it suitable for powering a wide variety of common, low-drain electronic devices across different settings.

Event or Professional Use

In more formal or commercial environments, this battery can serve as a replacement power source for equipment like attendance machines, electronic blood glucose monitors used in clinics, or tire pressure gauges in automotive settings. Its standard voltage and size make it a practical choice for maintaining the operation of such tools where consistent, low-level power is essential.

Everyday Home Use

For daily household needs, the battery is commonly used in devices such as television remote controls (like Xiaomi TV remotes), electronic dictionaries, body fat testers, ear thermometers, watches, toys, and perpetual calendars. Its application in personal weight scales is a key use case, providing the necessary power for digital readouts.

Benefits and Buying Value

The value of this product lies in its specific application for low-power devices and the clear communication of its product grade, allowing for an informed purchase decision based on intended use and quality expectations.

Reuse and Low Maintenance

As a primary (non-rechargeable) battery, its value proposition is one of direct replacement. The anti-leakage technology aims to reduce the risk of damage to the host device from battery fluid, potentially extending the device's lifespan between battery changes. The stable discharge voltage can contribute to reliable device operation for the battery's service life.

Why Choose This Product

This battery is a suitable choice for users who need a cost-effective CR2032 replacement for non-critical, low-power devices and who acknowledge the product description regarding its B-grade status. It is explicitly intended for applications where the highest grade of battery may not be necessary, such as in certain remote controls or basic electronic toys. For applications requiring guaranteed full charge or higher quality, the source recommends considering other batteries.
