What was the shape of the 12.06V though? The DVM was probably struggling to realise it was DC, try putting a large-ish electrolytic cap' across it to smooth it out and measure again.
Without smoothing capacitors (or a battery) it's not DC, though, it's full-wave rectified AC...
Hmm! I haven't seen a battery charger with a reservoir capacitor, a smoothing capacitor, a choke, or series resistor; yet such chargers are DC _in practice_, if not in theory. Thanks for reminding me about capacitors; in a conventional power supply they would raise the output voltage (not applicable in a basic battery charger).
Sylvain.
The DC voltage will rise when you attach a battery, as it will if you attached a cap, in the former to the battery terminal voltage, in the latter case to the peak voltage of the waveform.
They're not DC in practice, in pratice they supply a pulsed DC charge, hence why they're all rated at RMS. Wheras the rate of charge is the average current, which will be lower. Marketing :-)
The battery acts as a vast capacitor, though.

for the quick replies. I have now taken the back off and yes it

Don't buy anything from Maplins. My broadband started to go slow and my ISP said I needed a new filter. Maplins said I needed new cable. I bought new cable but the broadband speeded up again - must have been BT. So I took the cable back. But because it had been machine packed there is no way I would return it "in the same condition". The cable WAS "in the same condition". But the idiots said the packing had to be the same -- impossible!
If they want to get things back "correctly" they should use packing it is possible to pack.
Every other company I've taken anything back to, in living memory has accepted it back with full refund.
Except Maplins.
Don't even think of shopping with them.

Yes, you said that.
the goods had been used so they could not be sold on again as new they coud not offer a warranty on the product and in law if the goods are not faulty then thier is no reason why they should ecept them back

You've just said that...
You expect a Maplin shop assistant to be an expert on every product sold by them?

Not in the slightest, but I would expect them to know that for you to prove a cable was unsuitable for the purpose that you bought it for that you had to remove it from the packaging. I have seen a number of items like this in Maplins in taped or stapled packets so presumably some of their stores will accept them back. The only Maplins that I had any confidence in was in Milton Keynes where one member of staff, Marian, seemed to have a good working knowledge of most of their range and if not knew who or where to ask. Unfortunately she seems to have left.

He does seem to have a downer on Maplins at the moment, a couple of similar posts have appeared elsewhere today.

Eh? It's labelled with what it is. And in clear wrapping.
And are you happy to buy such secondhand goods? Or go for a new one further back on the rack?
Probably fed up with rude 'know it all' customers. ;-) It's a job I certainly wouldn't fancy. Although at least the MK branch has a better stock than most.

Hang on this wasn't my argument in the first place, I believe that Pauls point was that they wouldn't consider the return in anyway, OK it was not faulty so they did not have to accept it but it has been known in way of customer relations for them to do so in the past.
In the case of a lead would it really matter?
You know the population of MK well then!!!!! ;-)
(I'm not from MK, thank God)
It's turning into a Tandy rapidly though, although it did get me out of a hole a while back when I needed 50+ 5K6 resistors in a hurry i.e. I had the buses queuing up to have RT installed and they had fitted switch mode 24V 12V convertors with an over active shut down circuit that tripped as soon as it saw the radio attached.
Personally I prefer to buy from RS and Farnell, even Canford! But then I'm not normally paying the bill.
