They reset by themselves.... au naturel. But I usually talk to my dibby in a calm reassuring voice....
Here's my contribution for today; step one of follow-up on my really great idea that absolutely no one commented on. (so . . .. I know it's a big hit 
)
Was in sufficient proximity to a hardware store (or two) that the vortex sucked me in. Looking for "off-the-shelf" brass contact, disposable, or buy ten and rotate them. Wanted something that needed nothing done to it; just screw it in and go. I couldn't help myself tho. I gave it a quick swirly-rub on some 2000 grit laying on a flat surface.
#8 x 32 thread, 3/8" slotted flat head brass machine screw. 23¢. 20 second swap time. Proverbial freight train.
I had the brass screw in the background in there before (a pan head that I flattened). Surprisingly, 2 days of use on the first screw, popped in the 2nd . . .. . noticeable difference. Kin'a like this: Freight train → Passenger train [swap] Freight train. This'll keep me happy until Mundy's silver bullet arrives.
Step two will be, after repeating this experiment a few times, toss the used screw in the pickle and see if "unleaded" holds up as long as "factory" (with thin lead film)
oh, Lowe's did not have them. ACE did.

I didn't read the whole thing (I'm not that good). But, it left me wondering if resistance wouldn't increase right in the range we're wanting the lowest resistance. Like, if it's a 6A fuse and I'm driving through it at 5.8A . .. . is it thinking funny thoughts and starting to realign it's little particles?
I'll be honest with you and tell you I'm not that familiar with 'em. I'm sure there's more specific data available but it's getting late here on the east coast and my brain is slowly shutting down.
So, here's a 10A . . . . wait . .. what's a "hold current"? I read what the trip current was. Why does the 10A trip current fuse have a 5A hold current? Is that the level down to which it stays "tripped"? Or is the "hold current" the same as the "leakage current"?

The force is strong with this one
LOLZ!!! I don't know why but that made me laugh so hard!! I'm going to try it next time I'm in Best Buys... LOLOLOL! (I think it's the skipping... LOLOL!!!)

No idea what you're talking about. What I want to know is... why does the bottom of your dibi look like a ruler
? Can mine look like a ruler too?
Here's what you're looking for and I think your fuse is a better option:
Reviewing product specifications indicates that similarly rated PTCs have about twice (sometimes more) the resistance of fuses. Time-current characteristic: comparing the time-current curves of PTCs to fuses shows that the speed of response for a PTC is similar to the time delay of a Slo-Blo® fuse.

I think its a square? Do I win?
LOL! Mundy you are funny
. Does yours look like a square too then? What a great idea! Can use the bottom of your dibi to measure small things!!!

Would noalox keep the freight train running longer?
No idea what you're talking about. What I want to know is... why does the bottom of your dibi look like a ruler
yours also looks like a ruler. I just bought a new ruler for this batch. (pssssst . .. . in the industry.. . . of industriusness . .. .it's called a framing square
) Sometimes they happen to say something cute.
I didn't mean to imply that after two days the vape was weak. Just that there was a difference. I'm sure that Noalox would do something. Point of this effort was, instead of cleaning, perhaps a quick swap when swapping batteries. For those who don't like the idea of cleaning. Real world is that we almost none of us care enough about a 100% vape vs a 98% vape to be addressing this stuff on a daily basis. It's just that, if we figured out that it's all in the make/break contacts, and you could just as well use rabbit droppings for the rest of the circuit, and it's the micro-arcing-buildup of tarnish that really makes the biggest difference . .. . . . . well, I just wanted to offer a no-brainer, easy as pie, alternative.
AHA!!! perfect excuse for me to not work. Good.
Seriously, tho, I like as close to instant as possible. The less time that battery is percolating, the better. I was trying a number of fuses before settling on the one we're using. One of them was a "fast acting" glass fuse (AGC?). Anyway, I was shorting out the battery for 10 and 15 seconds, and although it started to melt, it never finished. Battery started getting warm. Looked it up. I think it said 2-4 minutes at 300%.
And that was just a different version of "fast".I think you mean that the current config is good for its purpose. It cheaper, readily available, requires no soldering and works. Better option...not so sure.
The parallel PTC fuse setup I used has a overall resistance of .02ohms. The trip rating at 8 amps is .5 seconds. Hire amps trip it faster. These are slightly slower than the Busman 10 amps, but if you get a hard short and put the battery max through your system, I am not sure if the 1/100 of a second is gonna make that much of a difference. The point of the fuse is to trip so if you do get an uncontrollable hard short, your battery doesnt go full discharge for a extended period of time.
But I am not the expert. Its a workable solution and it working great. Next best alternative for me at this hour was to go bare back with the berylium copper strip......
So to fuse or not to fuse, that was the question.
I was just about to say, that I'm sure one can select the Amp (trip) rating that does blow fast. It just wouldn't be a 10Amp one. (on the pptc)

I want you guys to know that I have been reading all this with great interest. I assume that by osmosis, I'm going to one day wake up and say... "EUREKA! I know what they're talking about!". I just don't know when that will be...
Meanwhile, I'll look at the pretty pictures
