On the ones I bought last year it was March of 2014 and on the new ones I just bought it is 2017. So the battery should be good for that long.

Hello John. To answer your question "what is the expiration date?"A box of 10 pkgs each with 6 batteries contained within was delivered the last week of December, 2012. Each pkg had an expiration date of 'Oct 2016' printed on the back of each pkg of six.This packaging allowed me a great value per battery and I am using the last package this week (7/08/13). So for six months I have paid roughly $0.42 cents per battery. And since I am a Prime user I did not pay shipping for this order. The size I ordered for my hearing aids is Size 10. I have tried many battery types and have my positive experience with the Rayovac size 10 has always been without issue. Good Luck. Hello John.

I honestly don't know but I've been buying these in the 60 pack for quite awhile and they don't seem to have a potency problem when I eventually get around to using them. Unlike normal batteries, these have a little protective tab - which I always assumed (but do not KNOW) keeps them fresh until its pulled off for us. Not really much help to you, I'm afraid. Just experience of use and opinion

The expiration date is listed on the top of the box. Usually it is a few months from purchase date.

It varies and dépends on the seller. For the ones we have bought in April 2015, the expiration date was January 2017.

I can't remember exactly, but when I got my box the expiration date was around 6-8 months I believe.

I bought mine a couple of months ago and they expire on 8/15. I have used expired ones in the past that have worked perfectly.

I'm not sure. I threw it in the garbage. Do you think they were expired? Why do you ask?

I had no idea there was an expiration date until I was asked the question! I looked at the one I already have, and It says November 2017. The expiration date is printed clearly on the bottom of the box.

Not that I can tell. Mine had an expiration of 3/2015. This is more of a question for the seller.

I am not sure, I bought it as a gift for my sister. Not sure the expiration date but I know she said she likes it.

I purchased mine in February and it expires in August. It's hard to say, that's more a question for the supplier.

Please always check condition note or confirm with seller. Our expiration date is at least 04/2018.

The expiration date varies according to when you buy the product. Based on my prior experience, the expiration date is about one year after date of purchase.

Mine expiration was 5/2016. Of course, I bought mine 6 months ago so any expiration date now could be into another month and year.

The expiration date is printed on the box top. My experience is that the date is usually about a year from date of purchase.

I cannot remember the exact expiration date I have already used these but I always check the expiration dates and they have never been out of date. I hope this helps you..Nate

I did not see an expiration date but I use mine faithfully everyday so it's gone before it would expire! Maybe check the website, I honestly don't know.
