How long will unopened cartridges be good for?

Probably a good question for Sophia Global. However, I have some unopened waiting to use, and the ink is still quite 'fluid'. Hope this helps.

It does not have an expiration date. The cartridges are good for as long as they remain sealed and unopened. The ink works fine in the printer after opening the package and removing the seal.

The brand I bought had an expiration date. That date was several years. Mine have lasted at least a year if unopened.

I haven't had to buy any replacement cartridges yet. I've had mine for several months, using it a couple times a week.

I've had mine about six months and just installed one of the cartridges. Worked great!

The expiration dates printed on the bottom of the carton indicate the latest date Epson can guarantee good performance of the ink. Additionally I understand the ink should be used within six months after opening the cartridge. I've gone past both dates with limited success - generally means I have to clean the print heads a little more often.

Each cartridge is wrapped individually. I don't know about shelf life. I have had absolutely no problem with these cartridges and they've saved me beaucoup $$$$.

As far as I can tell, I got these 25 May 2013. I posted my review 27 June 2013, and if memory serves, I installed two of the color cartridges not long before that, so at the time of installation I had probably had them about a month. I have no complaints. I would assume since they sell quite a few in a package, they don't expect them to dry up very quickly, and I believe I saw that they come with a 1-year guarantee. Hope this helps.

dont know if there was an expiration date on pkg. However, it depends on how much printing you doon how long cartridge lasts. Mine last 5 or 6 months.

I have not ever thought about a expiration date because they last quite a while unless you don't print anything out for a very long time or the room where your computer is quite warm then they may dry out. The room where your computer is is supposed to be cool. I have not had any cartridges to dry out even when I don't use them very much.

40 gallons OR 2 months...whichever comes first! I personally change mine at the beginning of each month because we use it so much and have very hard water. I would imagine that an unwrapped/unused cartridge would last at least a year or more.

I think the expiration date is on the packaging. It is not on the cartridge itself

From my experience. There is no way of knowing what the expiration date is for the cartridges being shipped. You will not know what the expiration date is until you actually receive the cartridge. The date is on the package when you receive it.

Didn't realize ink cartridges had expiration dates. The cartridges I ordered arrived tightly sealed in a foil-type envelope so I would estimate the cartridges would last an extremely long time.

I honestly don't know, but I have stored them for months before using them and have been able to switch them in mid-print without being able to see where the new cartridge was installed. I suspect you can store them a long time, but I would check the tech info on the Epson website for their recommendations.

Because the cartridges are sealed with a piece of tape and hermetically sealed in a plastic cup I would think as long as you store them in a cool dark place there shouldn't be a problem. The sealed cups have printing on them but not an expiration date,I've stored them for months without problems- and I live in the high desert.

Karen, I'm sorry I can't give you an exact date because I have thrown away the boxes since I installed my cartridges. I can tell you that I'm almost sure that you are good for at least a year.
