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.
