Duracell CR2025 Lithium Coin Cell Battery - 4 Pack

Both are 3V lithium coin cells with a 20mm diameter. The primary difference is thickness: a CR2025 is 2.5mm thick, while a CR2032 is 3.2mm thick. This seemingly small difference can prevent proper fit and contact in devices, so always use the exact size specified by your device.

No, Duracell CR2025 batteries are primary (single-use) lithium coin cells and are not designed to be recharged. Attempting to recharge them can be dangerous and may cause leakage or explosion.

The lifespan depends heavily on the device's power consumption. In low-drain devices like a watch or a remote, it can last for several years. In higher-drain devices, the lifespan will be shorter. Duracell's high-purity lithium generally offers reliable, long-lasting performance for the expected life of the battery.

When stored properly in its original packaging in a cool, dry place, Duracell CR2025 lithium coin cell batteries typically have a shelf life of up to 10 years.

Lithium batteries should not be thrown in regular household trash. They should be recycled at designated battery collection points or hazardous waste facilities. Check with your local municipality or recycling center for proper disposal instructions in your area.

No. While they share the 'CR' and '20' (20mm diameter), a CR2016 is 1.6mm thick, and a CR2025 is 2.5mm thick. The difference in thickness means a CR2025 will likely not fit properly or make reliable contact in a device designed for a CR2016, and vice versa.

1. Check Battery Orientation: Ensure the CR2025 battery is inserted with the correct `+` and `-` polarity, as indicated in your device's battery compartment. 2. Verify Battery Type: Double-check that your device specifically requires a CR2025 battery and not another size (e.g., CR2032, CR2016). 3. Inspect Contacts: Make sure the battery contacts in the device are clean and free of corrosion. Gently clean them with a cotton swab if necessary. 4. Test Battery: If possible, test the new battery with a battery tester to ensure it's fully charged. Though new, manufacturing defects can occur.

1. Device Drain: Some devices naturally consume more power, especially if they have constant wireless connectivity or display features. 2. Environmental Factors: Extreme temperatures (hot or cold) can reduce battery efficiency. 3. Improper Storage: Batteries stored improperly (e.g., loose in a drawer with metal objects, leading to short circuits) can lose charge prematurely. Ensure batteries are stored in their original packaging or a non-conductive container.

1. Incorrect Size: This is a strong indicator that you might be using the wrong battery size. A CR2025 is 2.5mm thick; if your device requires a CR2032 (3.2mm thick), a CR2025 will be too thin and may not make proper contact. Always use the exact battery size specified by your device manufacturer.
