About Duracell - CopperTop 9V Alkaline Batteries - long lasting

Duracell Alkaline batteries are suitable for a range of uses, including game controllers, battery lights, and more. Available in AA, AAA, C, D, and 9V sizes and are dependable and long-lasting for many of the devices you use every day - from remotes and flashlights to smoke detectors & toys, they're engineered to deliver the power you need for all your household devices. Duracell pioneered the Alkaline Manganese Dioxide electrochemical system nearly 40 years ago. Think of it like cooking a meal: Using different ingredients and amounts makes the meal taste different. Batteries should be removed from devices/equipment when: the device is not expected to be in use for several months; the batteries are worn out (to prevent possible damage from battery leakage); the battery is being powered by household (AC) current; and if you are not using your device, you will not be store batteries in a dry place at normal room temperature without the contacts touching. Extreme heat or cold reduces battery performance. Avoid putting battery-powered devices in very warm places. In addition, refrigeration is not necessary or recommended.
