Subject: why does a parallel battery connection have a greater capacity series?

Hi

I have been assigned a project dealing with battery life.
I've found that in  a series connection, the voltage is the sum of the 
individual cell voltages but the cell capacity is fixed at the value for 
the individual cell.
In a parallel battery connection, the capacity of the individual cells add 
to make the battery capacity, but the voltage remains as the voltage of the 
individual cell.

Why is this so?
This touches the heart of my project and I would be greatful for any 
assistance.

Thanks
Irene
