Each battery differs. Send an email to anyone who is selling one who has the price you are looking for and they will be able to tell you.

Don't know, battery does not have date of manufacture printed on it. However, the battery performs better than the original.

Mostly Chinese characters on the housing. I have long ago tossed the packaging if that had the date. I did find an 8 digit number in Arabic numerals....20090805. Whether that means it was produced August 5th of 2009 I don't know. I believe I've had this battery for the best part of two years with no issues.

The following data is on the back of the battery: CELL ORIGIN JAPAN FINISHED IN CHINA 20071108 RJA5133. The other battery I bought and installed as an OEM replacement has the same data and is still working great. However, to answer your question, I can not verify that this data represents the date of manufacture. Hope this helps.

Could find no date. Most is written in Japanese. Have had no problem since I began using it.

If it is on the battery, I am unable to see a logical date. Some batteries that I have purchased had the date on the package. I have disposed of the package for this battery. Lou

I don't see were it says that but it's most likely the date of manufacture. I got a set of these a while back (2011) and each individual battery has the date (01-2021) stamped on them. 10 year shelf life. ^_^

To be honest I have no idea. We needed a battery ASAP for my girlfriends work laptop. This was the right battery at the right price.

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.

I don't know the date of mfr. however, I've had the battery for over 2 years and it still holds a pretty long charge.

There is a sticker on the battery indicating the month and year of manufacture but you won't know until the battery is received. The four batteries I received were only 3 months old and the warranty does not begin until the date of sale. You'll have to contact the seller if you are really concerned.

I bought them a couple of months ago. I don't see a date anywhere on them but there is a stamped number of "43" on the battery. All the batteries were fully charged and I did not have any defective ones. I have bought the same batteries before from these people with no regrets.

There is no visible date on the package. But my results have been very good with these batteries.

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!

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.

I don't have a clue but I ordered the battery from Amazon only to find out I really didn't need it. Couldn't be returned because it is hazardous ...ok for them to mail to me but not for me to return to them. :(

All I know is that "24 WH" is printed on the battery specs. I hope this is the same thing.

Mine came at 4974, and is working fine so far (been almost a month). I get from 3-4 hours depending on what I'm doing. Coming from about a half hour on my 5 year old original battery, it's quite an improvement and well worth 26 dollars.

The battery does have a manufacture date, and according to Optima; any Authorized optima dealer can handle warranty, regardless of where it was purchased. I have not tried to warranty one, but I'm sure it would be a pain.

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.
