For a battery charger, you do NOT want a silicone rectifier, you want
a SELENIUM rectifier. Silicone diodes are far too flimsy and cant
handle the current load. Selenium rectifiers are made to handle all
the current you can pump thru them. and are made to be abused without
failing.

Good Lord, what ****ing rock have you been asleep under for the past
fifty year?

Are you saying the advice to use selenium rectifiers "stinks"?

Well then, are you insinuating that the advice to use silicon rectifiers
"stinks"?
Hmmm, I'd love to know where he recommends BUYING brand-new Selenium
rectifiers?

The powerhouse alternators that run without slip rings have a 10,000 Amp
rectifier mounted on the exciter. Yes, it is cooled by the hydrogen
atmosphere in the alternator, but that's a pretty hefty rectifier, less than
1 cubic foot, i think.

(For those who can't see the comma, that is 10 thousand amperes.)
