I have a charger for a Dyson V59. The nominal output voltage is 26v.
My meter shows the actual output voltage when not charging is 23.1v

Checking the voltage without a suitable load, is absolutely meaningless.

Many chargers don't output a voltage to a battery, unless they 'see' the
voltage of a battery at the output.
I removed the battery unit from the rest of the device and tried
charging it by itself. It does not charge and I can't measure any
voltage on the ouput terminals even when I press the power on switch.

The charger now shows a voltage of 6.3v with no load.

I have a dyson V6 fluffy here, I've just checked the PSU voltage from the 2.1mm barrel conector without a load and it's 26.3V .

Thanks. The V6 works fine with a replacement battery unit which just
arrived.
