Hi everyone!

Any reason why AC can't be used to charge a car battery? Reason I'm
asking is that I have an old Fedtro Powerhouse charger
which is outputting AC.

If this thing is ac, you need a rectifier. Need more info. You also
might need current limiter.

I'm reminded of some old chargers we had in the army, in the battery
room. Big box with switched levels of pulsating voltage to control
charge rate. I think the transformer had multiple taps. Charged and
cycled batteries about the size of motorcycle batteries. These were
for RCAT's , remote controlled aircraft targets.

you want to regulate the charge voltage,too.
go too high and you boil your electrolyte away,ruin your battery.
