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.

  • Common Questions


    Does the battery last 5 years in the smoke detector?


    No at the most, they last a year.


    Is it guaranteed for 5 years in storage? The date on the battery is 2024, which is the expiration date.


    I plan to review my supplies and use and replace before the storage expires, the company needs to be more transparent and remove from 5 years storage claim after time has passed. The company needs to be more transparent, or at least remove from 5 years storage claim after time has passed.


    Does Duracell have 9-volt batteries?


    These batteries can't be charged again.


    What is the expiration date of the batteries?


    When you can't open the package in the store, it doesn't state the expiration date on the package, only on the battery.


    I've bought many duracell batteries, but do these batteries leak like the other batteries?


    I did not have the problem.
