Coin cell battery Maxell CR1616 3V lithium, single piece

Maxell CR1616 3V lithium coin cell, single piece, is a compact battery designed to provide reliable power for small electronic devices that require a 3-volt lithium cell. The flat, round form factor and stable nominal voltage make it suitable for applications where a thin, long-life power source is needed. Supplied as one unit, this coin battery is intended for occasional replacements and spare use in consumer and professional devices.

Advantages

The CR1616 offers a consistent 3V output and low self-discharge, supporting long shelf life and predictable performance over time. Its compact dimensions allow installation in confined battery compartments while maintaining good energy density for its size. The lithium chemistry gives a wide operating temperature range and reliable voltage under typical light-load conditions.

Suitable for

• Wristwatches and small wearable devices
• Key fobs, remote controls, and car entry remotes
• Calculators and small electronic toys
• Medical devices such as glucometers and thermometers (where this cell size and voltage are specified)
• Measurement instruments and backup memory in electronics

Key specifications

• Chemistry: Lithium (Li) cell
• Nominal voltage: 3 V
• Cell type: Coin / button cell
• Physical format: thin, round coin shape suitable for small compartments
• Typical use: low-drain to intermittent-drain devices requiring stable voltage
• Pack quantity: single unit

How to use

Before installation, check the device manual to confirm this cell size and nominal voltage match the device requirements. Insert the battery into the compartment following polarity markings; the flat positive (+) side is typically visible. Ensure contacts are clean and free of corrosion, and close the compartment securely. Replace with a fresh CR1616 when device performance declines, display dims, or if the device indicates low battery. Dispose of used lithium coin cells according to local battery recycling and disposal regulations.

Usage recommendations

Store unused batteries in a cool, dry place away from direct sunlight and heat sources. Avoid mixing new and used cells or different chemistries in the same device. Keep out of reach of children and seek immediate medical attention if swallowed.
