Bob, I was answering Corby's query; mine had an original -hp- battery 
pack which I assumed was designed by someone who knew what they were 
doing, so I just put new Chinese made 2.2 Ah Nicad cells in it, exactly 
the same number as the original, however I don't know the capacity of 
the originals, they were unmarked.  Five or six years later it still 
will hold the thing up for at least twenty minutes, which I would think 
is what matters.

It would in any case be difficult to fit any more than 21 in the space 
available.
