Having discovered that recycling bins in various shops are a good source
of
lithium battery packs that can be put to various uses, I notice quite a
spread in claimed Ah capacities on the information labels.

The first aquisition was labelled "5.2Ah" - there weren't any parallel
combinations as it contained an uneven number of cells.

The next rescue was marked "4.2Ah", and contained 3 sets of parallel
pairs -
so I assume the individual cell capacity is 2.1Ah.

The next was lowest yet at 2.0Ah.

This seems to be quite a spread for apparently identical cells, so I'm
wondering if I'm missing something?!

Yep. You're missing 2 things.
1. You posted your question in the wrong newsgroup.

Its about electronics - so not as OT as most of the junk JT posts.
