    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.
