Is it 20 batteries, or 40 ???? You say in your advertising it's 40, then you say 20. Which is it ???

20 batteries. The 40 count is $19.99

When were these batteries manufactured to determine shelf life, also is the shelf life 5 or 10 years the ad states both, which is it?

Different battery has different shelf life,this one is 10 years.Hope the answer could help you.

Is this battery interchangeable with a E90 battery?

I have only used N batteries in the clocks that require N size and I'am not sure about multi use with E90.
