Watch owners, calculator users, and owners of compact electronic devices that demand a dependable 3V coin cell. The 2-pack configuration is particularly practical for households with multiple devices using the same battery format, reducing the need for frequent single-cell purchases.
Application of Energizer ULTI CR 2025
Identify the battery compartment in your device and confirm the CR 2025 / DL 2025 / ECR 2025 compatibility
Insert the coin cell with the positive (+) side facing up, as indicated by the compartment markings
Replace both cells simultaneously when one is depleted to ensure even performance across the pair
Store spare cells in a cool, dry place away from direct sunlight to preserve shelf life
Energizer is a globally recognized battery manufacturer headquartered in the United States, with over a century of experience in portable power solutions. The brand is known for its lithium coin cell line, which includes the ULTI series designed for high-drain and long-life applications. Energizer batteries are distributed worldwide and are a standard reference in the consumer battery market.
The CR 2025 is compatible with any device that specifies CR 2025, DL 2025, ECR 2025, or L12 battery types. Common applications include watches, calculators, remote controls, key fobs, small LED flashlights, and medical devices.
The battery delivers 3V nominal voltage using a lithium-manganese dioxide (Li-MnO2) chemical system, which provides high energy density, stable voltage output, and a low self-discharge rate compared to alkaline alternatives.
The coin cell measures approximately 20.5 mm in diameter and 2.5 mm in height, with a single-cell weight of 2.8 g. The 2-pack format contains two identical cells.
The package contains 2 Energizer ULTI CR 2025 lithium coin cell batteries. No additional accessories or charger are included, as coin cells are primary (non-rechargeable) batteries.
The battery comes with a 24-month manufacturer warranty. Shelf life is typically 5 to 10 years depending on storage conditions; actual service life varies based on device type and usage frequency.
