For a battery charger, you do NOT want a silicone rectifier, you want a

you can pump thru them. and are made to be abused without failing.

Good Lord, what fucking 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"?

Perhaps I was just asking him to confirm or otherwise expand on his statement against using selenium in this application, or (more likely) was that I was tweaking the old guys in this forum who remember exactly what odoriferous emanations a selenium rectifier provides as evidence of it's failure..

Golly I hope we can get this all cleared for peoples state of mind !!

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.)
