Tell me about it :-). I've never managed to

interested to hear them.
I have a World-War-II era book called "Accumulator
Charging", which goes into some detail on lead-acid
Nice...
FWIW, I have a number of older electrical/electronic books that cover
repairing accumulators (as in rechargable batteries, not registers :-)).
A couple of them even cover making them from scratch...
But this is for the traditional 'wet cell'. Not the gell-electrolyte ones
we're talking about. Doubtless the same principles apply, but the details
are sure to be different.
And I'm not sure I'd trust myself to be able to reassemble the case so
that it was properly sealed and didn't leak sulphuric acid all over my
nice computer...
batteries. I expect it'll say what to do,
but it may also
assume that you're willing and able to dismantle the
battery, fix it and then reassemble -- in the case of a 12V
battery, repeat for all six cells!
Ah, the joys of drilling out the lead connecting bars between the cells
and running a hot knife round the sealant so as to free the top of the
casing and the plates/separators...
And the real fun comes in the rebuild when you do the 'lead burning' to
put it all back together electrically!

I'll dig out the book and take a look -- I won't be able to
supply an ISBN, though, because it's too old for that sort
of thing!
Camdens must sell at least one book on this...
And you, coming from the west of England must know Camdens...
