Are people buying it as the "open end wire" option and then terminating it themselves (using the Digikey parts linked above)? Or will one of the two listed JST options work? Thanks.

I re-terminated mine.  I thought that I did something wrong as I would not charge the Tinybox but my charger just died.  I just got mine back from Jon today and this is the replacement charger that he recommends with the 5.5mm x 2.1mm barrel connector. (Currently Out of Stock)

Thanks for the info on the battery charger!

I soldered the end onto a new connector for the guy I just sold my tiny box v1 to. 

Can someone please through a voltmeter onto their charger and confirm + center and - outer with 8.39v across the two?

Ahhh, the 120+ days warning.
I know I'm on to something when I see that.

Well I've finally gotten around to replacing tinybox batteries!
And I picked the month that Jon is taking a break (I think) so I've come here to ask for advice.

I've dismantled the thing and pulled out the old battery, which is connected with a Molex connector which looks nothing like anything the new batteries came with. Here you can see how the fork fits into the old connector, which is still has the old battery wires locked in it and I can't pull it out. At least I haven't succeeded yet. I'd like to reuse that connector-- because I can't find one anywhere-- but those wires are push-locked in.

What I need is where to find the longer molex connector or how to get those wires free so I can shove the new battery's wires in there.

You need to use the old plug on the new battery!  The batteries don't come terminated.

Check!

But how do I get the wires OUT of the old plug without breaking it?
They lock in there tight!

Cut the plug off the old battery leaving some wire attached. Strip a 3/4 inch length of all wires. Splice the new to the old. Solder it and wrap with heat shrink.

Okay, now bear with me here...

I understood the assignment, and heat shrink is just beyond my capabilities right now, but here's what happened:

I managed to pull the wires out of the old plug and found this.
When pushed in all the way, this is the only metal that connects to the fork on the tinybox.
It's tiny, too, so I doubt seriously my ability pry it apart and reuse it, but its clear where the solder goes, at least, and I know I can do that part.

What is this meta piece called and where would I look for it?
