Panasonic CR2016 Lithium Coin Battery

The Panasonic CR2016 is a high‑performance, single‑use lithium coin cell designed to deliver reliable power for a wide range of small electronic devices. With a nominal voltage of 3 V and a capacity of 90 mAh, this battery offers an excellent balance between size, longevity, and energy density.

Key Specifications

• Model: CR2016 (also referenced as CR-2016EL/1B)
• Voltage: 3 V (nominal)
• Capacity: 90 mAh
• Diameter: 20 mm
• Thickness: 1.6 mm
• Type: Lithium‑ion (non‑rechargeable)
• Package: Single unit blister pack

Design and Construction

The CR2016 employs a lithium‑metal anode paired with a manganese dioxide cathode. This chemistry provides a stable voltage output over the entire discharge cycle, minimizing voltage sag that can affect sensitive electronics. The compact 20 mm diameter and 1.6 mm thickness make it ideal for devices where space is at a premium.

Performance Characteristics

• Stable Voltage: Maintains close to 3 V until the end of its life, ensuring consistent performance in low‑power circuits.
• Low Self‑Discharge: Typical self‑discharge rate is less than 1% per month, allowing long shelf life and readiness for immediate use.
• High Energy Density: The 90 mAh capacity delivers extended runtime in devices such as watches, key fobs, medical monitors, and remote controls.

Typical Applications

The CR2016 is widely used in a variety of consumer electronics where small form factor and reliable power are essential:

• Digital watches and fitness trackers
• Keyless entry fobs for vehicles and access control systems
• Medical devices (e.g., blood pressure monitors, glucose meters)
• Remote controls for appliances and entertainment systems
• Security alarms and motion sensors
• Electronic toys and hobbyist projects

Installation Guidelines

When inserting the CR2016 into a device:

1. Ensure the battery compartment is clean and free of debris.
2. Align the positive (+) side with the marked terminal in the compartment.
3. Gently press until the battery clicks into place, confirming secure contact.

Safety Precautions

• Do not expose the battery to extreme temperatures (above 60 °C or below –20 °C).
• Avoid puncturing or crushing; damage can lead to leakage or fire.
• Never mix new and used batteries in the same device.
• If a battery leaks, remove it immediately and dispose of it according to local regulations.

Storage Recommendations

For optimal longevity:

• Store at room temperature (15–25 °C) in a dry environment.
• Avoid prolonged exposure to high humidity or direct sunlight.
• Keep batteries sealed in their original blister pack until use.

Environmental Considerations

The Panasonic CR2016 is designed with environmental responsibility in mind:

• Contains no hazardous heavy metals such as lead or mercury.
• Can be recycled through appropriate battery recycling programs.
• Its long shelf life reduces the frequency of replacement, thereby minimizing waste.

Compatibility Summary

The CR2016’s standardized dimensions and voltage make it a drop‑in replacement for many existing devices that originally used other 3 V coin cells. Always verify device specifications before substitution to ensure optimal performance.

Conclusion

With its robust lithium chemistry, compact size, and reliable 90 mAh capacity, the Panasonic CR2016 stands out as a dependable power source for a broad spectrum of small electronic devices. Its design prioritizes stability, safety, and environmental stewardship, making it an excellent choice for consumers seeking long‑lasting, hassle‑free battery solutions.
