How does a lead acid battery charger (or car alternator) know
when to
switch to trickle charge? I can understand it noticing a drop in
charging current if the battery is on its own, but what if a random
changing load is connected, as there is in a running car?

The voltage perhaps.

Why would the voltage change?

That's the way batterys work, the battery voltage does change as its
charged.

That's determined by the alternator or charger.

Nope.

Yip.

Nope.

I can put any voltage I like across a battery's terminals.

Nope.

The battery then chooses how much current is drawn.

And that current changes depending on the how charged the battery is.

Let's say the charger/alternator gives out 14.4V initially, to
charge the
battery quickly. It'll just sit at 14.4V forever, providing the
charger
can give out enough current to charge the slightly flat battery
and power
any connected loads.

Its more complicated than that with the current going to the
battery and the
battery is charged.

If the battery had no loads connected, it would take a lot less
current
when it became full, but the voltage would stay the same.

No it doesn't even with a very crude battery charger.

For example, I'm currently keeping my car's battery topped up with a
bench supply overnight. It's set to 13.8V, with a current limiter
only to prevent overloading the supply.

It actually specify the current being supplied.

The voltage stays at 13.8V all the time, sometimes 100mA is drawn,
sometimes up to 4A. The only way I or the supply can tell the
battery is full, is by the current dropping to 100mA. But it's
actually always full, as when 4A is drawn, that's going to a load.

What load ? There no load with a battery being charged with a bench
supply.

Correction

Nope.

the *battery* is the *load*.

Not when the battery is fully charges and is being charged
with a bench supply that is delivering 4A to the battery.

Take the case of an alternator charging a battery at ~4 amps. The
battery is the load and it also provides, as part of that function, the
reference *voltage* that the alternator *must have* in order to control
the output.

You are 100% correct.

You do realize who you are dealing with here, right? Here is some of
the other BS he posted and then just continued to lie about, refuse
to acknowledge it was all wrong:

How can one dope be wrong on so many things?



The 737 MCAS doesn't rely on just one AOA sensor (It does)

The FAA would never approve that design (They did)

[snip]

You've already posted all that ****e. Repeating yourself is a sign of illness.

No, arguing with the Aussie troll who has a track record of BS and lies
is the illness. Maybe you don't care about anyone's credibility and
will debate nuclear physics with the village idiot who lies about most
things. Do so at your own risk.

He may be an argumentative prick, but he does know a fair bit about a lot of things.

And you're the one that keeps going on and on about things he's said. You're trolling him, I'm arguing and discussing with him.

Feel free to get a room with the asshole. He's the troll, not me. Arguing
is exactly what the troll wants. There is nothing to argue about. Rod
made some specific claims, I asked for any references to back it up, he
has come up with NOTHING. Capiche?

What's this obsession with references? FFS grow up.

Yeah, better to just make stuff up on the fly, like you and Rod.
Now go **** yourself.
