Do these batteries have a "use by" date, if so what is it?

Yes, they do have a date on them. I bought them in Oct/Nov 2014 and the date on them is 06-2016. Hope this helps. They have been working great. I had the old ones for about 14 months when they started to only be good for half a day. They wanted $50cdn for 2 in Canada and I got these for about $12-14 for both. We'll see how long they last.

Bought mine Oct/Nov 2015 and they have a use by date of 6/2016.....same as the date reported by the person who bought in Oct/Nov 2014. Not happy with 7 month date--was planning to keep them for at least a year as a backup set.

Mine had a use-by date that was about 9 months from when I bought it. Each package has its own expiration date, I'd assume.

The latest batteries will have a MAR 2024 expiration date on them. Each seller may have different dated stock so be sure to check the description for the item condition. You may have to ask the seller directly if the info is not listed.

I can not find a date on them. The markings on the batteries are very small can not read even with magnification

There is no mfg date or expiry date on these batteries. However they worked fine. At couple of dollars and free shipping I am not complaining.

my batteries indicate 11/2018. I find them most unsatisfactory and will not buy them again.

its similar to the date on milk, meaning they are best when used before that date. They will work after and depending on the environment which they were stored in also plays a roll on how well they will perform over time. I have used other batteries and have found that the surefire batteries exceed almost all other batteries for endurance. BTW, all batteries have dates. I hope this helped. One last thing, the light bulb over time can loose strength as well, so it would be prudent to check the condition and I try to make a habbit to replace the light bulbs when they prove to be taxed by use.

my batteries had a " best by" date on the side of each of the batteries. The date was 4+ years from the date of purchase. as I use 10 at a time to replace smoke alarm batteries this was an adequate shelf life for me.

I am not sure but I would assume that it would be the date of manufacture. I say this because the 123A batteries have a 10 year shelf life and that's why our fire dept bought the lites and batteries for our professional use. I mauy be wrong and it may be use by date but the ones I bought are full power and I've had no problems with them. Hope this helps.

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

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.

wow, i just now looked at what i got and mine had 12/17/2010. You better ask the seller if you are indeed going to get that kind of battery because they don't usually give you what is posted on the site. better be sure before buying.

I bought two batteries at about the same time. One has a date of 2007 and the other has 2010. I don't know which seller was which, but both batteries have performed beautifully and were well worth the purchase.

I looked and looked and all can see is the print date of the pack box that they came in. But I've gone through almost my first box of three and they are some darn good batteries. I use them almost weekly in flashlights and on weapons sites. I have no complaints on their quality.

A note on the package I received mentioned 2006. That was not a "good until" date, but I took it to be the date of manufacture. That being said, the batteries are working fine in my scientific calculator.

There is no expiration date anywhere that I can see. These batteries I received are fine. After this, I bought another 10-pack of batteries of a different size. They were all dead. Same vendor. I am torn about continuing with him. But my Maxell LR41 batteries were fine. No problems.

The date on the front side of the Battery is the Best used by date. The number on the bottom of my batteries looks more like a manufacturing control number than a date.
