You said something about watching the polarity across
the output of the charger -- what exactly did you mean?

The plus output of the charger goes to the plus terminal
of the battery.

I'm aware of that. I was asking about how the polarity of
the AC output affects how the capacitor should be placed?

AC has no polarity.

Exactly my point. So does it matter how the capacitor is
placed across the output leads?

You wouldn't normally place a capacitor across /any/ device with an AC
output. The only obvious uses that come to mind would be for stability, or
to mop up high-frequency junk. Neither would be likely in a charger.
