Duracell 2025 jednorazová batéria CR2025 lítium

The Duracell 2025 CR2025 Lithium single-use battery is a compact 3 V power cell designed for small electronic devices that require CR2025 size batteries. With a 20 mm diameter and 2.5 mm thickness, this coin cell provides steady voltage and reliable discharge characteristics typical of lithium chemistry. The pack contains two batteries suitable for devices that demand a thin, long-lasting primary battery.

Advantages

Duracell CR2025 batteries offer stable 3 V output and long shelf life, maintaining usable capacity during storage and delivering consistent performance in low-drain and intermittent-use devices. The lithium construction provides a high energy density in a slim form factor, and the sealed coin-cell design resists leakage under normal usage conditions. These features make the battery suitable for applications where compact size and dependable operation are important.

Suitable for

• Watches and fitness trackers requiring CR2025 cells
• Calculator and small electronic toys
• Key fobs, remote controls, and car alarm remotes
• Motherboard CMOS backup and small sensor devices

Key specifications

• Battery type: single-use (primary) lithium coin cell
• Nominal voltage: 3 V
• Physical dimensions: 20 mm diameter, 2.5 mm thickness (CR2025 form factor)
• Number of cells in pack: 2 pieces

• Typical use: low-drain to moderate-drain portable electronics

How to use

Install the CR2025 battery into the device according to the device manufacturer’s polarity markings, ensuring the flat side with the positive sign faces the indicated terminal. Before replacement, power off the device if recommended and remove the old battery safely. Use a small non-metallic tool where indicated to avoid short circuits; avoid touching both sides of the battery simultaneously with metal tools. After installation, verify device operation and dispose of used batteries in accordance with local regulations for battery recycling and hazardous waste.

Recommendations

Store batteries in a cool, dry place away from direct sunlight and heat sources. Do not attempt to recharge single-use lithium cells, and keep them out of reach of children. Replace batteries in pairs or as specified by the device manufacturer to ensure balanced performance when multiple cells are required.
