Where is the date of expiration on these batteries?

The pack I have shows 10 13 on the side. Not5 sure if that is the expiration date, or date of manufacture??

the "10" as first digits means manufactured in 2010. Realistic life expectancy of battery is 8.5 years. You should buy only ones with with "13" or "14" and not a "10"

That is the expiration date. These batteries have a 10 year listed shelf life. If you just received some with a June 2012 date, I would recommend returning for a refund. The ones I got expire in 2022.

There is no expiration date on the batteries, however the book says to periodically charge them; switch off power; and/or remove battery for extended storage - these all are to extend battery life. It also says the 3V /800mAh lithium ion batteries are available from Ambient Weather - so they must eventually die!

It is my understanding that the date code on the batteries are manufacturing dates. No expiration date. Week number/year, ex: 0813, the eight week of 2013.

Yes, the batteries are fresh. They are working fine. I don't see an expiration date on the package or on the batteries themselves.Regards,Bruce

There is no expiration date in the description which is understandable because it would change with each new batch of batteries. The ones I bought had an expiration date three years in the future. Their performance has been equal to any others I have used.

The batteries I received had an expiration date of January 2014. I bought them in September 2014. I will never buy batteries from this seller, or on Amazon at all, ever again.

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.

Hi, good question. Don't see an expiration date anywhere on the package. The other batteries I bought from store has 2+ years before expiration. So far it has been working fine for my car remote. Good luck.

The batteries I bought have a date of almost 5 years after the date I bought them.

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. :)

I think it depends on who the distributer is at time of purchase; they seem to change over time. The last batch of these batteries I received did not have expiration dates printed on either the battery or its packaging. I don't recall ever seeing dates physically printed on the batteries, although I have seen them printed on the packaging. But you'll have to trust the date on the packaging is correct, especially if the packaging looks like "re-packaging". The best way to tell if the battery you are about to use is fully charged (or check the batteries when you receive them, like I do) is to use a simple, inexpensive voltmeter that has either an analog or digital scale that measures at least 3.6 volts.

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