Button cell battery everActive CR2025 3V lithium, single pack (no retail packaging)

everActive CR2025 3V lithium button cell (single pack, no retail packaging) is a replacement battery designed for small, low-drain electronic devices requiring the standard CR2025 size. The cell delivers a nominal 3 volts and the long shelf life and stable output typical of lithium coin batteries, making it suitable as either a direct replacement or a spare battery. Supplied individually without retail packaging, this unit is identified by manufacturer code BAT2025.eA1 and EAN 3100000952990.

Advantages

This everActive CR2025 provides consistent 3V output and low self-discharge for extended storage life. The lithium chemistry ensures relatively high energy density in a compact, 20 mm diameter, 2.5 mm height coin cell form factor (CR2025), offering reliable operation in low-drain applications. The single-pack format is convenient for users who need one replacement cell without additional packaging.

Suitable for

• Wrist watches and fitness trackers that accept CR2025 cells
• Key fobs and car remote transmitters
• Calculators and small electronic toys
• Blood glucose meters and medical monitoring devices that specify CR2025
• Computer motherboards, CMOS backup, and other low-drain circuits

How to use

Before installation, confirm the device specifies CR2025 size and 3V nominal voltage. Remove the discharged cell from the battery compartment using appropriate tools or fingernails, taking care not to damage contacts or the device housing. Observe correct polarity when inserting the new everActive CR2025: the flat side marked with the positive polarity (+) typically faces outward. Close the battery compartment securely and test the device for normal operation. Dispose of the spent lithium cell according to local battery recycling and hazardous waste regulations.

Usage recommendations

Store the everActive CR2025 in a cool, dry place away from direct sunlight and metal objects to avoid short circuits. Keep out of reach of children. Replace batteries in pairs where equipment manufacturer guidance recommends it, and follow device-specific instructions for safe replacement and disposal.
