Button Lithium Battery Duracell CR2450 3V — coin cell for watches, calculators and electronics

Duracell CR2450 3V is a lithium coin cell designed to deliver stable voltage for devices that require a compact, long-lasting power source. This 3-volt button battery is suitable for a range of small electronics where consistent output and long shelf life matter. The slim, round design makes it easy to fit into watch compartments, calculator slots, key fob housings and other compact enclosures.

Advantages

The battery offers a stable 3V output over its usable life, supporting reliable operation of low- to moderate-drain devices. Its lithium chemistry provides a long shelf life and good performance across a broad temperature range. The coin-cell form factor ensures simple, tool-free replacement in most consumer devices, while the construction minimizes self-discharge for extended storage.

Suitable for

• Wristwatches and small timepieces
• Calculators and portable electronic displays
• Key fobs, car remotes and security tokens
• Small medical devices such as glucometers and thermometers
• Various low-drain sensors, fitness trackers and toys

Key specifications

• Nominal voltage: 3 volts
• Cell type: non-rechargeable lithium coin/button cell
• Typical use: low-drain to moderate-drain electronic devices
• Form factor: flat, round coin cell with standard diameter and thickness for the CR2450 size
• Storage: long shelf life when stored at recommended conditions

How to use

Before installation, ensure the device is powered off and identify the correct polarity orientation for the battery compartment. Remove the depleted battery using a suitable tool or fingers, taking care not to damage the compartment contacts. Insert the new Duracell CR2450 3V with the correct polarity and secure the compartment cover. After replacement, verify the device powers on and functions normally. Dispose of the removed battery according to local regulations for battery recycling.

Usage recommendations

Store batteries in a cool, dry place and avoid direct exposure to heat or open flame. Keep coin cells out of reach of children and pets; accidental ingestion can cause serious injury. Use the battery only in devices specified for the CR2450 size and nominal voltage.
