Is the date on the bottom of the batteries the manufaturing date? Is the date on the front side of the batteries the expiration date?

I cannot answer the question about the manufacturing date; however, I am most concerned about the date of use. My batteries are to be used by 2019 - I am certain that by that date I will have ordered several more boxes. This is the second box of 9volts that I have purchased and I have been very satisfied.

like everyone esle mine expire 2018,but look for cryptic date coding for batteries on line,below is wwhat i found..hope it helps.(shown here as example)The First Digit is the year of Manufacture the next character (a letter) is the month of Manufacture the next 2 (numbers) are the day of the month of Manufacture The final 2 letters/numbers are manufacturing plant (I don't have that list) For example, to decode "2F11J2": 2 = 2012 F = month, where A = Jan, B = Feb, etc. F = June 11 = day of month J2 = unknown Plant Therefore; 2012 June 11 (or June 11th, 2012). So be a smart consumer and take advantage of the deals you find on Duracell 7-year or 10-year batteries, with cryptic "Date Coding"!!!

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.

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.

Hello Amy. I don't know what the date is...I need to look at the battery. That information was on the description of the battery as being up to date, therefore, I assumed the battery would be fine. But that was not the case. I still have the battery.

I checked and the date is on the package and not on the battery. The exp. date is 03/2017. Hope this helps.

The expiration date would depend on the batch number of the batteries that you actually get. I ordered batteries on July 26, 2014 and they have a expiration date of March 2021.

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.

The only date on Duracell batteries I know of are the expiration dates, but they spell out the month, eg. Mar 2016.

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.

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.

There is no way that we can know the expiration date as it is not stamped on the package. However, the Sony batteries that I ordered are performing well and I am satisfied.

Yes, the date on the bottom is the date of manufacture.The date on the front is the expiration date.

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

The outside box has no date on it. Each individual battery is marked with a "Best Before" date of March 2018. I purchased them January 16 2014, so it is a safe bet that current batteries will have a different date. For what it's worth; These batteries have exceeded my expectations. I have a number of wireless motion sensors that are in relatively high-traffic areas during the day. Previous batteries of another brand, always alkaline, never lasted more than about 5 months in those devices. These batteries, put into use January of 2014, are still going strong as of October 16 2014. The outside box has no date on it.

The expiration date is going to depend on when the batteries were made. Each lot will have a different expiration date. And even with a printed best used by date the manufacture's date would be under ideal conditions. You would also have to take into consideration exposure to light, heat, cold, etc.

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.

The batteries have a reference number, a lot number and an SN number on them. But no date that I can see. I charged them when I got them. The first set of four I bought in 2012 and the second set of four in 2014.

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

I received mine in a small box. Each battery was upright, not terminals touching. The date says "1114A", which I guess means the batteries aren't expired. Nevertheless, that they are opened is worrisome.
