3V Button Battery CR2032 CR2025 CR2016 Alkaline Coin Cell 20mm

This 3V button battery is a coin cell power source for small electronics that require a compact alkaline battery. It is offered in CR2032, CR2025, and CR2016 model options, giving a choice of common button cell references. The battery has a standard voltage of 3V, a 20mm diameter, and a 3.2mm height. These measurements help buyers check physical fit before ordering. Typical uses include watches, calculators, key fobs, and similar small devices. The source information lists alkaline as the material and does not state capacity, shelf life, or pack quantity, so those details are not claimed here. This description focuses on the confirmed battery type, model options, voltage, size, and practical use.

Features and Construction

The main construction details are simple: this is a button battery with alkaline chemistry, a 3V standard voltage, and a coin cell shape. It is available in three model options. The listed diameter and height provide the key physical specifications for checking whether the battery suits a device compartment.

Material and Build

The battery is described as alkaline and uses a button cell format. Alkaline chemistry is a common type for household small electronics, and the coin shape allows it to fit shallow battery compartments. The source does not provide information about capacity, discharge rate, or shelf life, so no performance claims are made beyond the stated type, voltage, and model options. The model options are CR2032, CR2025, and CR2016. Buyers should match the model code shown in their device or old battery.

Size and Practical Fit

The stated diameter is 20mm and the height is 3.2mm. These dimensions are useful for checking clearance in watches, calculators, key fobs, and other compact devices. Because the source does not list separate dimensions for each model option, the 20mm diameter and 3.2mm height should be treated as the available size information for the product listing. Always confirm the required battery size and model code before fitting.

Uses and Placement

This button battery is intended for small devices that take a 3V coin cell. Common examples include watches, calculators, and key fobs. It may also suit other compact electronics where the model and dimensions match. The product is not described for high-drain or specialist equipment, so use should stay within the stated small-electronics context.

Event or Professional Use

For workplaces, offices, or service counters, a 3V button battery can be kept as a replacement for calculators, small clocks, and key fobs. The CR2032, CR2025, and CR2016 options cover several common model references, which can simplify stock selection. The source does not state pack counts or trade quantities, so bulk purchasing details should be confirmed before ordering. Fit and compatibility remain dependent on the device requiring the correct model and size.

Everyday Home Use

At home, this battery type is typically used for watches, calculators, and small remote or key fob devices. The 20mm diameter and 3.2mm height make it easier to compare against an existing battery. The model options allow a direct match with the old battery code. No claims are made about lifespan or capacity because those figures are not provided in the source. Keep batteries away from children and dispose of them according to local rules.

Benefits and Buying Value

The practical value of this listing comes from clear model options, a stated 3V voltage, and defined dimensions. It helps buyers match a replacement button battery without guessing at the main physical details. The alkaline construction is stated plainly, and the product is positioned for small electronics rather than specialist applications.

Reuse and Low Maintenance

Button batteries are replacement items for devices that need a fresh power source. This product offers CR2032, CR2025, and CR2016 options, so a suitable model can be chosen for compatible devices. The source does not state how long the battery lasts, so no maintenance or lifespan claims are made. Routine care is limited to correct installation, dry storage, and safe disposal.

Why Choose This Product

Choose this battery when a 3V alkaline button cell is required and the device matches one of the listed model options. The 20mm diameter and 3.2mm height give useful size information for checking fit. The listing avoids unsupported claims about capacity or shelf life and focuses on the confirmed battery type, voltage, model codes, and dimensions. Confirm the model code and size in your device before purchase.
