TET doesn't specify exactly which Japanese cell it uses

I just bought the charger from Thermovape. I don't like stressing over little details.

Just slower. This is not rocket science, though from the discussions here it seems like a lot of people think it is.
The TET factory supplied battery provides about 3000mAh. If your charger can supply 1A of current, it will take approximately 3 hours to charge a depleted battery (while the charge process isn't 100% efficient, the battery also won't be totally dead, so for a "pretty much" depleted battery will take about 3 hours). If you charge it at a 500mA rate, it will take about 6 hours; 600mA rate, about 5 hours. If you charge it at a 2A rate, it will take about an hour and a half; 3A rate, about an hour.
There are lower and upper limits to the amount of current you can supply when charging a battery. If you supply too much current, you will reduce the number of cycles you get out of the battery; if you supply way to much current, and you're not using a protected battery, you'll blow up the battery. If you supply too little current (say .1C or less, or 300mA or less for the battery we're talking about), it will take forever to recharge the battery (10+ hours), and depending on the design of the charger, may fool it into not recognizing the end of charge cycle properly (though this does NOT generally happen with lithium based batteries, only NiMH batteries).
Keeping in mind that TET emphatically says that you MUST use a protected battery, it's not likely that you can overcharge their battery to the point of it venting (exploding). TET doesn't specify exactly which Japanese cell it uses, nor does TET exactly specify what the values are for the protection circuit it incorporates. The protection circuitry for a lithium battery is designed to prevent the charger from supplying too much voltage and current and from letting the battery discharge at too great a rate, or to too low a voltage. That's its purpose in life.
Also typically for lithium cells of the type that TET supplies, you can discharge at a rate up to 2 or 3 C (i.e., 6 to 9 amps for the cell in question). Charge rate maximums, however, vary greatly depending on the cell's exact chemistry and physical design, so it's not wise to speculate without knowing exactly which cell TET is going to settle on. Some lithium cells (not the one that comes with the Cera!) are designed to be charged at up to 15C. In no case do you have to worry about charging at .5C, which in this case is 1.5A. There is also no safety concern that I've read about charging at the 1C rate, which is 3A; charging at the 1C rate likely reduces the number of charge/discharge cycles slightly compared to charging at .5C rates. That said, the real answer for maximum charge rate should come from TET, not from me or anyone else here. The protection circuit they use will also impact the maximum charge rate, as that's one of the parameters it's "protecting".
I use one of those "complicated computer controlled charger/dischargers" that Noah mentioned, and so I can program what rates and voltages and methodology are used. Unless Noah tells me otherwise, I plan on charging my Cera battery at the .5C rate (1.5A) if I'm in no rush, and the 1C rate (3A) if I am. Before I charge it at the 1C rate, I plan on getting permission from Noah.
Speaking of which, why speculate...
Hey Noah: What is the recommended and maximum charge current for the new Cera cells?
OK
In Noah's reply to me here is a link to a listing for the Pila IBC charger. Is there another Pila charger?
I seem to recall he only specified "Japanese", not "Panasonic". He also mentioned (somewhere) that TET had found some good Korean manufactured cells, and that as cell technology improved, TET would keep up on providing the best cells that money can buy.
SIDE NOTE:
Chargers. BTW a note on chargers. The Tenergy charger we sell works very well for charging the Japanes cells. It works better then a wf-188 or equivelent. If the PC is tripped the Tenergy charger reliable resets the PCB instantly upn insertion in the charger bay.
If you want the "best" charger for vaping IMO, without going really crazy with programmable/configurable chargers is the Pila brand.
Batteries: AW batteries are the best batteries, made in China. Panasonic cells from Japan, and Samsumg Cells from korea both outperform AW cells. ANY CELL/BATTERY USED IN THE CERA MUST BE PROTECTED.
IMHO it is best to avoid purchasing the newest. highest capacity battery. They tend to not outperform the cell just below (largely because of optimization wit continued production). So what I mean is that if you can get a 3300 mAh panasonic, or a 3100mAh, or a 2900mAh. There will be very little/if any perceived performance improvement.

Allright, everything is blurry... closing eyes.

I believe this was the post in question. Way back on page 46.
Was a pain to find but I remember he said Tenergy in there somewhere.
Well, just bit the bullet and got a Cera on order...the Mrs is buying, for Christmas....so may the wait be short and sweet.
For the TET guy's...any rough idea on when my Cera would be built and ready for shipping if the first builds do start tomorrow ??
Sorry, I don't think I understood your post correctly...did you say YOUR WIFE is buying this for you? I sure hope you bought her one hell of a Christmas present
I'm buying my wife lots of really nice gifts, in preparation of her finding out I bought the Cera.
How do you order just the charger it wont let me. When i try to order the charger only it makes me order another cera .I just bought the charger from Thermovape. I don't like stressing over little details.

Although never tested, my guess is Cera will perform just as well in dog houses. just make sure you have a couple extra batteries.
So I guess what I really want to know here, is what will happen, if I use the Xtar WP2 to charge the TET battery. Will it blow up, kill the battery, just charge slower etc... that's what I am trying to work out at this point.
Not any slower, I would bet the same or maybe faster:Just slower. This is not rocket science, though from the discussions here it seems like a lot of people think it is.
Nope, the USB setting is an output for charging your phone from a battery:Yep, they're talking USB port output, not charger output. It's 600mA (or less) it seems there (where it counts).
If that's OK for you will have to remain your call, I've no free advice for your situation I'm afraid.
Actually it seems like a input rating, the changer is powered by a USB port, there'd be no reason to have a USB charge port on it.
