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.
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.
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.
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.
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.
