There is a CMU (Charge Management Unit) underneath all that wrapping.
Many thanks Zumad. That might well be the DPPM unit that is mentioned in the battery system menu.

Well we may give that impression @bar2 , but I hadn't got a clue until I Googled DPPM. It seems to manage the charging of the battery so I guess that DPPM is the same as a CMU, but spelled a bit differently. Its only 4 letters different !

And really, if I I had aspirations of being technical, I could probably make a start by not frying the battery in the first place.

Given that info, it might be worth throwing good money after bad and buying a new battery. But I'd then have to solder that in too. Hmmm. I wonder if one of my soldered joints moved while it was cooling and has gone 'dry'.

See my update to post on 6th December - a few posts back.

Today, I discovered something really important. I found another way that doesn't work.
