5 year shelf life from the date of manufacture is great -- what was the date of manufacture of these sticks? (or what is the expiration date?)

The seller gives you their latest batch and I remember I did not have any issues as far as the expiration dates are concerned. But just to give you the heads up, the yellow which was rated by the manufacturer as their brightest product, is not that REALLY bright. The green ones are far better IMHO.

These should last for 5 years. if someone in 2014 said they were dated 2019, that means that they are being sold 50% expired. I want to buy batteries to store for long term emergency use. Is there a way to get these batteries right after they were manufactured?

Not sure about expiration dates, but they work fine and last long - even if left in a drawer for weeks at a time. Great buy, especially if you think how expensive they can be over the counter in a retail store.

I'd like to give a correct answer to this question but the truth is that I bought them for my brother-in-law who is a "Jelly Bell" freal and they never last long enough to find out the shelf-life but I would think a long long time.

They appear to last a very long time, as long as you keep them in a sealed bag. It doesn't appear to have an expiration date on them. However, I'm sure they have some sort of arbitrary date listed somewhere.

I had mine for 7 months and between making pb, snacks and cooking with them I used them and never had issues with then expiring. Though I never saw an expiration date.

I believe it is 1 year, they are freezed dried so as long as you keep the comtain in your house the shelf life does not change.

There are no expiration dates on any of the stick I have bought. I have used opened ones for up to two years and they are still potent! Ammonia seems to keep it's power forever. I Give these for gifts each summer to friends and family. We all 'swear' by them.

The expiration date is on the bottom of the bottle. It looks like they are good for at least 5+ years

the package I have says they were produced in December of 2012 and their "Best Before" date is December 2014. Seems like a decent shelf life to me.

I don't remember the exact date, but when I received mine, they had very nearly a full 5 years before expiration.

I've eaten all of mine, but I want to say they had either a six or twelve month shelf life, at the least. They never last that long in my house!

I do not know the published shelf life, but I have used one year old product which worked just fine. You might want to check with manufactuor or review product data sheet.

There was no shelf-life indicated on the tiny sticker. Maker says 10-yrs....Hummmm.... Some suggest "keeping them in the freezer." I think that idea defeats the purpose of monitoring occupied spaces. Unless of course they are living in their freezers. :o)
