What is the expiration date on the duracell mn9100/lr1 batteries you will send me.

There is no way, of course, that I could know the answer to your question; however, I purchased 4 of them for an HP-41CX calculator and have been very pleased. Most alkaline batteries have a "shelf life" of several years, so I doubt if anyone can tell you what the "expiration date" might be. All in all, I don't think you'll be disappointed.

Is there a aaa battery that is short in length? i have a decoration that needs aaa but the space is very small. are there aaa button batteries?

N cells look like short AAA cells, but I don't know if the diameter is the same. Make sure what voltage your decoration needs. N cells are 1.5 volts and their use is rare. I'd take the decoration to a local Fred Meyer or equivalent and check out what they have.

Are they rechargeable ?

I do not believe they are. There is nothing written on the package that states "rechargeable". Hope this helps.

Working grand.

Bought these for a little clock in my campervan, doing the job rightly. Cheaper than buying individually at timpsons.

Work as they should

No complaints. These were from Asia and had Chinese writing on them. However they were real Duracell and were fully charged, package was intact and batteries working well
