transformer battery charger

Anyone desired to build this transformer

Any opinion to what voltage the 1 microfarad capacitor will be charged ?

[fritznien]

about 340 volts.
your turns ratio is all one to one.
so v in = v out.
a battery charger has no need of filtering,
what it needs is voltage and current limiting so you don't cook the battery.

I don't think he has to worry about cooking the battery.
When the 240 volts hits the battery there won't be any pieces left big enough to cook. 
Where in the world did that schematic come from?

@fritznien

thanks a lot. one of the best style answers I've got at all.
lets assume battery can handle enormous charging current.

and lets assume there is some resistance on "the battery side"

charged capacitor voltage is = ... 340 Volts again ( around 340 Volts) ?
