Quad list it as a 4V battery - quite how they achieve that is

question altogether!


** Quad have " 4.8V NiCd " printed on the schem next to it.



It might be the charger's nominal upper voltage limit for a 3 cell
NiCd
(blue) or 3 cell NiMH (green) battery. Constant current charging
of
either type results in a 'resting voltage' immediately after going
off
charge in the region of 1.4 volts per cell, usually dropping to
1.36
volts after a day or two. The 1.2 volts rating for these cells is
the
minimum voltage just prior to becoming exhausted of useful charge.


** The rest voltage of a NiCd cell is 1.25V - under a moderate load
it drops to 1.2v and is exhausted at 1.1V.

When trickle charged in memory back up use, there is just enough
charge to compensate for internal self discharge - normally about
C/50. So for a nominal 150mAh cell, that equates to a 3mA trickle
charge.

A good condition, 4 cell pack ought to measure between 4.8 and 5V.


This one reads 4.6V.

I've been in touch with the seller. I've had a couple of messages.
Last week's was 'I'll sort it next week'. This week's is the same
;-)

It turns out that he hasn't (he says) used the tuner for some years.




The truth will out...............



I wish. At first he admitted (by email) that he hadn't used the tuner
for some time - 'forgotten when I last used it'. Now he's adamant that
it worked at the time of sale. He's willing to give me a £30 refund, but
I'm not overly happy about that so I may take it to the ebay dispute
thingy. Problem being I can't prove either way, it may have taken a
knock in transit - although his dishonesty is now on record, so that
might help.

On the up-side, had an email from Quad - £48 plus VAT fixed labour
charge, plus parts and postage, to 'full working specification'. That
seems like a very good deal, so I may take them up on that.

Still a bit cross that I paid for a 'very nice' FM4.
