How to Use
Match the plus and minus ends to the markings inside the battery compartment and insert the batteries firmly. Replace all batteries in a device at the same time and do not mix old and new cells or different brands, which shortens run time. Store spare batteries in the original box at room temperature, away from heat and metal objects, and remove batteries from devices you will not use for months. Keep out of reach of children and recycle used cells where local rules require it.

Are Duracell batteries safe and what precautions should I take?
Alkaline batteries are safe in normal use, but keep them out of reach of children and pets and never let a child put a battery in their mouth. Do not short-circuit, puncture, heat, or burn batteries, and never recharge them. Remove leaking or exhausted cells promptly. Recycle used batteries where your local program accepts them.
