Is there a way to determine the manufacturing date of this battery or the age of the cells? Who is the manufacturer of the li-ion cells inside?

there is no date code on package or batt. however you can mark battery with a sharpie.

Wouldn't know since I tossed mine when it wouldn't hold a charge. I would not recommend this product.

Julian, You are correct. The date of manufacture will be found on a label that is affixed next to the battery door. The label will include the Model Number, an Assembly number and the date.

Most likely the manufactured date since I don't think they would accurately be able to predict the exact expiration date of the battery. I think shelf life is about 10 years

No idea on what the manufacturing date is but I still use my LG g2x daily and this is the only backup battery I have and it works great.

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.

The camera for which I bought this battery is still new to me. I bought the battery as a back-up and have only charged it once. It is new and my past experience with other lithium-ion batteries for other cameras leads me to believe that this one will continue to do its job for at least two or three years. Sorry I cannot be of more help.

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

I don't see a manufacture date on my battery and doesn't work the way I would expect. The battery does hold a charge for quite awhile, but the saw turns off a lot. Not sure if it is the battery or saw.

I haven't used it that much, so I really don't know. However, I suspect it somewhat. Hmm ... I noticed the build date was 3 years before I received the battery.

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

I don't know. But what I do know is that it's a great battery. Is working well and has been. It's a great buy

Yes it is the same, I am guessing it has an older manufactured date, but not sure. Some of the other batteries I have purchased are like that.

There is no manufacture date printed on the battery. I bought the camera and battery in Summer 2013.

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. ^_^
