It is not that simple:

The charge reduction algorithm  is incorporated in any decent charger to protect the battery lifespan  

 it is simple 

Both devices need to have PD. If one of them doesn't have a PD, it works in the old way aka USB 2 (to ensure backward compatibility). Same for USB adapter.

You can use any charger, it just will take longer. But in order to charge two batteries in parallel, you need 27W on the USB port of your charger. Most multiport chargers are below that. If you are be

Are you sure the new battery (BP-SCL6) does not work with the old charger? After all, Q3 is being shipped with the new battery and the old charger, and I am confident I was charging BP-SCL6 with the o

I’m sure you are right regarding the specs. However I have had no issues whatsoever when mixing devices and USB types. Some are twenty years old. My main charging block has both USB A and USB C outlets and there adapters just work.

Likely suboptimal charging. If one wants to be on the safe side, stick with 1A and accept very long charging hours ;)

Dunno. My original M8 batteries from 2006-2007 still hold plenty of charge. The only ones that needed a rebuild were my DMR ones, but they are notorious for dying.

I "bricked" the Garmin Inreach Mini with a 2,4A charger. The device takes in only 2 watts. I got it replaced quickly by warranty. It happened to me when I was in the middle of the sea. 

Bricked Garmin Inreach is very common. 2nd version got the USB-C instead.

If one charges Leica batteries with the original charger, there is nothing to think of. Buying Chinese 3rd party chargers adds new headaches especially when you mix chargers like 2.4A but thankfully we got USB-C. 

My Epson Rd1 battery holds well. I need to remind myself to top up it sometimes. 3rd party batteries died quickly. 

The Leica charger offers to charge up to 80%  on SLC4 which is nice. I already use the charging system between 20%-80% to ensure the longevity of the batteries. Phones, laptops, whatever. 

LFP is quite nice and can take abuse, unlike Li-lion.

This is the key info.  Without the higher wattage the charger runs the batteries in sequence rather than parallel.   Took me a bit to figure out.

Charging an SL3 battery in an older SL2 or SL charger  doesn't seem to work, since those batteries had a lower capacity.

New battery delivers 18% more capacity, other then that I can not see why SL2 charge would not charge this battery.

You can kill a device with a 65w USB2 charger if the device supports max 35w.

But USB-C has a communication protocol and gives only the required voltage/wattage the connected device asks for. 

The pinout diagram of USB-C is below. USB 2 pinout is simplistic, with only 4 pins, and has no communication to a device for the required wattage delivery. 

See the yellow-colored CC1 and CC2.

Any item be it battery charger or camera that is connected to a USB C would have in its input a voltage and current regulator thus protecting the rest of the electronic circuitry.

I tried using my old SL2 charger to charge an SL3 battery and found it wasn't working.  I think it is because my SL and SL2 kits are pre-USB C

No.

The regulator is used for only sending current. How does the regulator know how much to send? The output device receives the info from the input device and then charges at the proper voltage and current. 

The receiving end has some form of protection of the circuit. It would be overheated if the desired voltage/current is not properly communicated. Thats why it has old USB compatibility.

I am referring here to the devise i.e. camera having voltage and currant regulator. Potentially you could have a power supply capable to deliver 1000A and 5 or 8 Volts and the internal regulator limiting it to down the lane to the rest of the circuit to say 8V and 1A. Refer to the Ohm Law for further study.

A new SL3 just arrived. I also purchased a USB-C Dual Charger BC-SCL6 with a second battery. I assumed the charger could simply be plugged into 120V AC, but as the name implies, the only port is for a USB-C cord. Can I simply plug the charger into one of my Apple Mac computers, using a USB-C cable?  Or, does it require an adapter of some sort – the charger instruction sheet notes a USB-C AC Adapter (Leica ACA-SCL6) but does not specify use.  Thanks!

Sure you can use an Apple charger if it is at least outputting what 27 watts.

As some have said above you can absolutely use your apple charger. I've used a small ipad charger (the 18w one I think) and it works although slowly.  

By far the worst thing about the new charger is there's no branding on it. When I'm charging at my kids events with other dad's there's no way for them to know how much better I am than them.

I’ve found that if I put a ‘4’ and ‘6’ battery in the charger together, only the ‘6’ charges. The ‘4’ will only charge if I remove the ‘6’.

Interesting. I have 2 of each. They are all full but I'll try next time I charge.
