Button cell battery set ANSMANN CR2025 CR2032 CR2450 3V — multipack of lithium coin cells

Set of ANSMANN lithium button cells including CR2025, CR2032 and CR2450, each rated at 3V. The multipack supplies three common coin cell sizes for small electronic devices: thin and compact cells for watches and key fobs, and a larger diameter cell for devices that need higher capacity. These lithium cells provide a stable 3V output and a long storage life typical of modern coin cell chemistry, making the set convenient for household spares, office use, and basic repairs.

Advantages

The set combines three widely used battery sizes in a single pack, reducing the need to buy separate types. Lithium chemistry offers stable voltage over most of the discharge cycle and a long shelf life, which ensures reliable operation after storage. Cells are pre-packaged for easy storage and selection, and their standardized dimensions fit equipment designed for CR2025, CR2032 and CR2450 coin cells.

Suitable for

• Wristwatches and wearable electronics
• Remote controls and car key fobs
• Calculators and small household gadgets
• Wireless sensors and small IoT devices
• Motherboard CMOS/RTC backup and other electronics requiring 3V coin cells

Key specifications

• Cell types included: three lithium coin cell sizes (thin, standard, and larger diameter)
• Nominal voltage: 3 volts per cell
• Chemistry: lithium manganese dioxide (typical for CR coin cells)
• Application form factor: button/coin cells compatible with device battery holders
• Storage life: long shelf life characteristic of lithium coin cells (months to years when stored correctly)
• Operating temperature: suitable for normal consumer electronics operating ranges

How to use

Select the correct cell size for your device by checking the device’s battery compartment marking or the original battery. Insert the cell with correct polarity, ensuring the positive (+) side faces the indicated terminal. Close the battery compartment or holder securely and verify device operation. Replace cells one at a time to avoid losing configuration data in devices without backup power. Dispose of used lithium coin cells according to local battery recycling regulations.

Usage recommendations

Store unused cells in a cool, dry place away from metal objects to prevent shorting. Avoid exposing cells to high temperatures or direct sunlight. When replacing batteries in sensitive electronics, document settings if necessary and handle cells with clean, dry hands or non-conductive tweezers to prevent contamination and accidental short circuits.
