• Precise dimensions (12.5 mm diameter, 2.0 mm height) ensuring a perfect fit in standard CR1220 slots.

Performance Characteristics

The 35 mAh capacity of the Panasonic CR1220 provides sufficient power for low‑drain camera accessories such as remote triggers, wireless flash units, and small electronic viewfinders. Its lithium chemistry offers:

• Low self‑discharge rate, preserving charge over extended periods.
• Wide operating temperature range (typically –20 °C to +60 °C), suitable for outdoor photography in diverse climates.
Consistent voltage output throughout its discharge cycle, ensuring stable performance of sensitive camera electronics.

Applications in Photography

While the CR1220 is commonly found in camera accessories, it also powers a variety of other small devices that benefit from its compact size and reliable power delivery:

• Remote shutter releases – enabling precise timing for long exposures.
• Wireless flash triggers – allowing photographers to control external flashes without cables.
• Electronic viewfinders and small display units – maintaining clear, flicker‑free operation.
• Camera memory card readers – providing the necessary power for data transfer.

Longevity and Shelf Life

The Panasonic CR1220 is engineered for long shelf life. Lithium coin cells typically retain up to 80 % of their original capacity after five years when stored in a cool, dry environment. This extended longevity makes the battery an excellent choice for photographers who may not use certain accessories frequently but require them to be ready at a moment’s notice.

Compatibility and Installation

To ensure optimal performance, always verify that your camera accessory specifies a CR1220 or equivalent 3‑V lithium coin cell. The battery’s standardized size allows for straightforward installation:

1. Open the battery compartment on your device.
2. Insert the CR1220, aligning the positive (+) side with the marked slot.
3. Secure the cover and test the accessory to confirm proper operation.

Environmental Considerations

As a lithium coin cell, the Panasonic CR1220 is designed for single‑use applications. While it offers excellent performance, responsible disposal is essential to minimize environmental impact. Recycle the battery through local electronic waste programs or designated collection points.

Summary

The Panasonic CR1220 Camera Battery combines a compact form factor with reliable 3‑V lithium chemistry and a solid 35 mAh capacity, making it an indispensable power source for camera accessories that demand precision and durability. Its standardized dimensions, low self‑discharge, and wide temperature tolerance ensure consistent performance across a range of photographic equipment.

Whether you’re capturing fleeting moments with a remote shutter release or managing wireless flash setups, the Panasonic CR1220 delivers dependable power when it matters most.
