I've not yet tried it connected to a battery but it now powers on
without clicking and connecting a DVM to the croc clips shows around
12.06v or 6.02 on the 6 volt setting. I shall give it a test on a
battery tomorrow.

Is your meter reasonably accurate?
These voltage readings seem rather low.

I think the battery charger voltage increases when connected to a
battery,

That would be a clever trick. ;-) Unless there is some form of
electronics
regulating the output the open circuit voltage should be very much higher
than that. Have you measured the AC voltage direct across the transformer
- ie the input to the rectifier?

I will check it out tomorrow. cheers.



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.
