Is that clear?

Yes, so why have the semiconductor fuse at all?

FUCKHEAD !!

Look at the circuit diagram. The positive of the battery is only connected through a capacitor. How can a capacitor possibly pass DC current to allow the battery to charge?

What else might that yellow thing be, other than a capacitor?

A thermistor or a VDR, to provide current limiting.
Regarding operation, power diodes tend to have a higher Vf than small
signal diodes or transistor junctions, so once the diode goes into
conduction it produces a large enough voltage to turn on the
transistor and the red LED, indicating that charging is taking place.
The green LED merely indicates that power is applied to the circuit.

My (probably futile) hope was that he might answer it himself,
or at least try to...

I didn\'t expect two completely different devices to look identical. So how the fuck am I supposed to tell which one is?

Try an ohmmeter.
Not so easy when in the middle of a big circuit.

One end of it is connected only to the battery which I believe you can remove.

In this case yes, but I was talking generically in other larger circuits where the capacitor/limiter could be in the middle of loads of other components.

You could

Think hard about it

or

Ohm out all around it and solve the puzzle

or

Unsolder and measure

or

Maybe look up the part number, if it\'s public. Lots of part numbers
aren\'t.

Maybe it\'s an AC battery? They are very useful for grid
storage applications as long as you can control the phase.

What makes you think that component is a capacitor? I\'m
assuming you drew the schematic.
I\'ve learned from someone on Quora that it\'s actually a PTC Fuse
- a resettable semiconductor fuse.

The second image in the link shows a brown disk, which I thought
was a ceramic capacitor. Looks like it\'s to stop a busted battery from
being overcharged when a cell has died.

It won\'t do that. It is simply a fuse that prevents too high a
current from flowing, such as if you connected the battery backwards.
Surely a higher current would flow if the battery became 9 cells
instead of 10 because one failed and became zero volts? Ever tried
charging a car battery with 14V when it only contains 5 working cells?
The others boil.
I\'m not sure what this circuit is supposed to do. It doesn\'t look
right to me.
It\'s the (5 hour) charger for a very cheap cordless drill. The
input is a 14.4V wall wart. The output is to a pack of NiCad cells.
It\'s worked fine for years, until I can no longer find replacement
NiCad cells, so I\'m converting the battery packs to LiIon.

My point is this circuit isn\'t setting the voltage or limiting
current other than through the fuse.
It will be limited by the wall wart, which is a basic transformer and
diodes. Since it\'s a 5 hour charge, it won\'t harm the battery to just
keep going.
It appears to be a couple of LEDs that indicate the battery is
charging and/or has power.
Yes, the battery is basically just charged through the diode and fuse.
The diode will prevent the transistor from ever turning on more than
a tiny amount, but with the gain of the transistor the red LED is
turned on with a small current in the transistor BE path. It could be
more clear if you redraw it with the base on the right, the resistor
to the right of that and the diode across the two. The two resistors
and the green LED probably should be on the left, where power comes
in. That\'s all they do is indicate the presence of power.
Yeah it was just a quick sketch to try to understand it.
In any event, it is the wall wart that would seem to be doing all
the work of charging the battery, setting the max current and the max
voltage just by having a significant series resistance most likely.
Ah, you beat me to it.
That\'s why the fuse is not needed for a shorted cell. Being at 11V
instead of 14V isn\'t enough to make the current jump so much. A short
or reversed battery is a different matter.
Unless NiCads are vastly different to car batteries, one shorted cell
makes a hell of a lot more current flow.

THE WALL WART LIMITS THE CURRENT AND PREVENTS ANY ISSUES FROM A SINGLE
SHORTED CELL.

Is that clear?

Yes, so why have the semiconductor fuse at all?

In case the jumper leads going to the battery being charged are shorted
together, stupid.

Oh, you use google groups. My god man get a newsreader program.

As I said, when you reverse connect the battery, you double the voltage in the circuit. Rather than having a difference of a couple of volts in the EMF opposing the current, you now have a voltage that is perhaps 10 times that total. Yeah, that\'s going to push some unreasonable current though the power pack, so the fuse is needed.

Since the battery pack, like any cordless drill, has a semicircle shaped connector, it cannot possibly be connected backwards.

[Brian Gaff (Sofa)]

Its called a lossless charger. I encountered something like it in an old
pifco charging circuit in a torch. From what I could see one rectifier one
large capacitor and a small bleed resistor across the mains pins was all
supposed to charge two flat Ni-cads, and it was fine until the capacitor got
leaky, and the room filled with nasty smelling smoke.

I\'m just guessing here, since I cannot see your circuit, but it used to be a
very common practice for small rechargeable devices.
