FAQs

What kind of devices use Duracell Ultra Photo CR2 batteries?

These batteries are commonly used in high-drain specialized electronics such as digital cameras, photo flash units, smart home sensors, keyless entry systems, smoke detectors, high-performance flashlights, and some pet training collars.

Are Duracell Ultra Photo CR2 batteries rechargeable?

No, Duracell Ultra Photo CR2 Lithium Batteries are primary (single-use) batteries and are not designed to be recharged. Attempting to recharge them can be dangerous.

How long can these batteries be stored?

Duracell Ultra Photo CR2 Lithium Batteries come with a 10-year in-storage guarantee, meaning they will retain their power for up to a decade when stored correctly in their original packaging and in a cool, dry place.

Can I use CR2 batteries interchangeably with other battery types like CR123A?

No, CR2 batteries have different dimensions and voltage compared to other types like CR123A. Always use the exact battery type specified by your device manufacturer to avoid damage or malfunction.

How should I dispose of used Duracell CR2 batteries?

Used batteries should be disposed of responsibly. Many communities have recycling programs for batteries. Check with your local waste management services for proper disposal instructions, and do not dispose of them in household trash or fire.

Will these batteries work in extreme temperatures?

Lithium batteries generally perform well across a wide temperature range. While the product description doesn't specify an exact range, they are suitable for outdoor use in cameras and other devices. For optimal performance and battery life, avoid prolonged exposure to extreme hot or cold.

Troubleshooting

Device not powering on after new battery installation

Ensure batteries are inserted with the correct polarity (+ and - ends). Double-check that your device specifically uses CR2 batteries and try a fresh set if available to rule out a faulty battery.

Device performance is poor or inconsistent (e.g., flash recycle slow)

Verify that the batteries are Duracell Ultra Photo CR2, designed for high drain applications. If the issue persists, the device itself may have a fault or higher power requirements than anticipated. Check for any 'low battery' indicators.

Batteries seem to drain quickly

Ensure the device is powered off when not in use. Some devices have standby modes that still consume power. Check if the device is defective or has a power leak. Also, confirm the batteries are not past their 'use by' date, though Duracell CR2s have a long shelf life.
