If you have additional questions please contact our Customer Relations team at 800-551-2355 between the hours of 9am and 6pm EST. **Q: What is the expiration date on the 9V 4-pack?** A: It's the date usually found on the btry. On my last purchase of Duracell 9v coppertop btry's MAR 2015 is printed on the btry. The package, while it has no good to date on it says it is guaranteed fresh for 5 years. On this packaging you can not see a good to date on it until you open it and look at the btry. Therefore since it is gtd for 5 years I believe the manufacture date was 2010. Using a top rated btry like Duracell we change smoke alarm btrys every 2 years contrary to the suggested 1 year time frame of replacement. We also check the alarm function every month. We also use these 9v btry's in our garage door openers. Hope this answers your question.
