what is the expiration date on these batteries
1326656
Mine are dated to expire on Sept 2018. I purchased these batteries because they were advertised as "longest life", which I interpreted to mean "longest operational life". I was told that what Rayovac meant was that they had the longest shelf life. In fact, based on my own experience, these Rayovac batteries have an operational life only 75% as long as the PowerOne batteries I was using. To add insult to injury, I paid more for the Rayovac batteries on the mistaken assumption that they would give longer operational life!

There last me two weeks (that's the 312A per 48 to a package. Remember to disconnect nightly when removing prior to bed - just like turning your cell phone off to save from roaming.

I don't see a date on either the package or the batteries, but they are working for me.

They have a manufacture date of 2012/04 stamped on them and the use before date printed on the battery is Mar 2021. It seems to me they say 10 years but mine aren't allowed to lay on the shelf that long. I like them. I use them. And I reorder them. I prefer the Duracell.

I'm not a vendor; I'm also a customer. Sorry I can't tell you what the expiration date was as I discarded the packing. If you store unused batteries in a zip-locked plastic bag in a refrigerator, they won't "leak" their charge.

I received 2 of the Exide RF- 31D batteries on July 19, 2013. I just checked the factory date on the batteries. Both batteries were dated June 2013. I use the batteries on my solar backup system and they are holding up well.

I ordered some a few weeks ago, and they've been working fine. I don't have them in front of me so I can't tell you what the expiration date is, but my recollection is that it was at least 2016 or later.

Mine just arrived on 16 June 2015 and the code on them are 1215 meaning they were made just a few months ago in the 12th week of this year 2015. Very fresh batteries. Good for 10 years.

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?

I got mine three months ago and mine expire in 04 of 2016. I like these batteries and they are the bet I have found.

Hello. To be honest, I didn't check the expiration date on mine, but I will tell you that I purchased them about a year ago and they are still working just fine. Hope this helps. :)

The expected life span of these batteries is approx. 1 year give or take a few months. My last set lasted 2 years

Don't even know if they have an expiration date, but mine have performed as expected. Replaced the original Panasonic batteries and have been doing the job for over 6 months. A good replacement battery.

I have not found an expiration date on any that I have ever purchased. I have never had a problem with the batteries going dead before other types I have used

I don't know, but I suspect they were older batteries when I received them because they did not last very long
