Duracell CR2025 Lithium Coin Cell Batteries (2 Pack)

The Duracell CR2025 is a 3V lithium coin cell battery sold in packs of two, designed to power small electronic devices that require a 20mm diameter, 2.5mm thick cell. Common applications include car key fobs, fitness trackers, digital watches, bathroom scales, calculators, remote controls for garage doors and security systems, and LED candles.

Lithium chemistry delivers stable voltage across the battery's discharge curve, which means devices powered by CR2025 cells continue to function reliably until the cell is depleted rather than exhibiting gradual performance decline. The 3V output is standard for devices designed around CR2025 specification, and Duracell's manufacturing ensures consistent voltage delivery under both continuous and pulsed loads.

The two-pack configuration provides an immediate spare when replacing a depleted cell in a device, reducing the need for emergency trips to a shop when a key fob or fitness tracker stops working. Duracell CR2025 cells carry a shelf life of up to 10 years when stored at room temperature, making them suitable for keeping in a drawer or toolkit without concern over self-discharge.

Each cell measures 20mm in diameter and 2.5mm in thickness, adhering to the IEC standard for CR2025 size. The blister pack uses Duracell's child-resistant packaging that requires scissors to open, reducing the risk of accidental ingestion by young children.

What devices use CR2025 batteries?

CR2025 cells are commonly used in car key fobs, fitness trackers, digital watches, bathroom scales, calculators, remote controls for garage doors and security systems, medical devices such as glucose meters, and LED tealight candles. Any device specifying a CR2025 cell will accept this battery.

How long do CR2025 batteries last?

Battery life depends on the device and usage pattern. In a car key fob used a few times daily, a CR2025 can last 2-3 years. In a fitness tracker with constant Bluetooth connection, expect 6-12 months. In low-drain devices like a bathroom scale, the cell may last several years.

Can I use a CR2032 instead of a CR2025?

No. While both are 20mm diameter 3V lithium cells, the CR2032 is 3.2mm thick compared to the CR2025's 2.5mm thickness. A CR2032 will not fit in a battery compartment designed for a CR2025, and forcing it can damage the device.

What is the shelf life?

Duracell CR2025 cells have a shelf life of up to 10 years when stored at room temperature in the original packaging. This makes them suitable for keeping as spares without concern over self-discharge.
