When were these batteries produced? NiMH go bad after 3-4 years....

I have about 30 eneloop NiMH batteries that were made in 2006 that still work great today. I use them in remotes, radios and flashlights without any issues. They were and still are made in Japan. I also have about 50 eneloop batteries made in 2010 that work great as well. I think a good smart charger helps with prolonging their life.

My pack of AA purchased in January 2015 says 2014. I did not know NiMH goes bad 3 - 4 years. How did you find out this information? I have been using rechargeable batteries for years with no problems without NiMH. I just checked a different package of AAA purchased in January also & it says 2011. Gee your never too old to learn a valuable lesson. Thanks so much for informing me about this. Have a great day. VRLT

Well, this unit is just bad. Send it back, have another one sent out. I've had mine at least 3 years, maybe more and I use it for all things with batteries. It's been a good unit, your unit is just bad.

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 get long life with fully charged NiMh rechargeable AA batteries. But, NiMh batteries lose at lot of their charge when sitting idle for a few weeks, so I carry a set of lithium batteries as a "backup". The lithium batteries can stay "fresh" for ten years or so, ideal for an "emergency" set of batteries. I know a lot of folks who only take 200 or 300 photos per year. That sort of person could get a year (or MORE) of use from one set of lithium batteries on the Fujifilm S700, without the "hassle" of carrying a charger on their trips.

There were no expiration dates on the battery, the packaging, or the outside wrapper package. I will say they all look like they are in very good condition, none of them were swollen (which they will do if they have been exposed to heat or old) and so far all the ones I've used over the past 4 or 5 months have worked great. The Brand I received says "WAMA" "Micro Lithium Cell" at the top with an icon of a calculator at the top.

Doesn't seem to have a clear Manufacture date. This battery is almost identical to the original battery NA1BA04CS/4-B vs NA1B14DS/4-B (Not sure which is the original any more) if this helps, but its the only info that is different on the batteries. The two i have are so similar I can't tell which is the original. I even Googled it and not alot came up with identifying a positive manufacture date for this battery. sorry I couldn't answer your question, but I hope this gives u some benefit, anyway I think it is worth the buy considering its probably less expensive than at a battery store or a walmart type store if u can even find 1. My the odds forever be in your favor!

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

I was unable locate expiration date, only manufacture date is on each battery.

Sorry, there is no date on the batteries. I don't know what the guarantee period is. From experience over the past 10 years or so, the batteries remain useful for 4 or 5 years.

The Low Self Discharge Batteries are listed as LSD NiMH. In my opinion these pictured here work fine for me since I change batteries on a couple of pest deterrents about every 1 to 2 months. LSD NiMH batteries will keep most of it's charge for a year or 2. If you are planning to keep batteries stored for a year or more I would suggest sticking with the standard Duracell's and Eveready's. They hold their charges way longer. Rechargeable batteries are for toys and devices that frequently need a battery change. Here is a link to a Wiki on the question that you asked. Hope this helps. http://en.wikipedia.org/wiki/Nickel%E2%80%93metal_hydride_battery

George I got my first xmc-31 5 years ago. I am an avid fishing guy and figured 5 years was pretty good. So I recently bought another one to replace it. They are great batteries.

Mine are dated 2012. Official Energizer batteries and most batteries in general with have a specific expiration date.

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 checked my batteries and I don't see any OEM on the label...Label states only Amazon Basics rechargeable/AAAHR03/NiMH 1.2V 800mAh/Standard Charge:80mA in 15 hours/Do not disassemble, short-circuit,or dispose of in fire. Made in China/Mfg. Date OCT 2012 No other writing or indicators on them...they work a treat, though...I am very happy with them in my household cordless phones!

I don't see a date on them, but I have ordered these batteries 3 or 4 times for at least 10 years. They last as long if not longer than the ones provided by the home security firm. I can't give you a time space, but they work quite well for me.

These are a high quality battery. Youre looking at a long shelf life. Right around 10 years or so. Obviously this varies depending on storage and brand quality. And of course they will slowly loose some energy every year. They are high quality reliable battery. Thats why they started getting used in flashlights; was due to the long shelf life.
