Which 8650 do I own? Cause I need a battery!

[chastings]

I bought an 8650 from ebay - $20 - works great on a charger, dies when disconnected.
Where can I find a battery?
Also, the tablet came with a charger... 12VDC. I thought it was kinda weird, since every other tablet I own has 5 or 5.5VDC.
Is that the right charger?
And where can I find a manual?
TIA,
C
