CR2032 B-Grade Lithium Button Battery for Weight Scales and Low-Power Electronics

This product is a CR2032 lithium manganese button battery, categorised as a B-grade or second-class electronic component. It is specified for use in low-power devices where top-tier performance is not critical, such as weight scales, car remote controls, computer motherboards, and various household gadgets. With a standard voltage of 3V and a rated capacity of 160mAh, it provides a basic power source. Potential buyers should be aware that as a B product, a small proportion of units may arrive with insufficient charge or be completely discharged; orders are placed on this understanding, and returns are not accepted for this specific issue. Customers requiring higher reliability are advised to consider other battery options.

Features and Construction

This battery is built to fulfil a specific, budget-conscious niche in the electronics market. Its specifications and construction are tailored for applications where cost is a primary factor.

Material and Build

The battery utilises lithium manganese chemistry, which delivers a stable 3V output. The casing incorporates a wear-resistant and high-temperature-resistant steel sheet, a feature that contributes to its stated anti-leakage performance. This construction is designed to prevent electrolyte leakage under normal conditions, enhancing the battery's suitability for long-term installation in devices like weight scales or perpetual calendars.

Size and Practical Fit

The CR2032 format is a standardised button cell size, measuring 20.0mm in diameter and 3.2mm in height. These dimensions ensure compatibility with a vast array of consumer electronics designed for this common battery type. Its compact profile makes it easy to install and replace in tight compartments found in remote controls, thermometers, and toys.

Uses and Placement

The battery's performance profile dictates its recommended applications. It is expressly intended for low-drain electronic circuits.

Event or Professional Use

In professional or commercial settings with high volume and low cost-per-unit requirements, such as supplying batteries for disposable promotional electronics, basic attendance machines, or low-priority backup systems, this B-grade battery can be a practical choice. Its specification meets the fundamental needs of these applications without the expense of premium-grade cells.

Everyday Home Use

For everyday household items like TV remotes (including Xiaomi TV remotes), electronic dictionaries, toys, watches, and simple body fat testers, this battery provides the necessary 3V power. Users should be mindful of its B-grade status and the possibility of receiving an occasional unit with reduced initial charge, which is a trade-off for the lower cost.

Benefits and Buying Value

The value proposition of this battery centres on its affordability and functional suitability for defined, undemanding tasks.

Reuse and Low Maintenance

As a primary (non-rechargeable) battery, its main benefit is a 'fit and forget' installation for the duration of its life in very low-power devices. The anti-leakage technology is a practical benefit aimed at protecting the device's battery contacts from corrosion over time, potentially extending the useful life of the host product.

Why Choose This Product

This battery is chosen primarily for its low cost and standardised form factor. It is a viable option for hobbyists, bulk purchasers, or for use in non-critical devices where battery failure is a minor inconvenience. The clear labelling as a B-product sets accurate expectations regarding reliability, allowing informed purchasing decisions based on application criticality and budget.
