I got the Chichitecs 2 x 1800's plus charger today, didn't even notice the slightly thicker batteries until it was pointed out in this thread. The case does take slightly more effort to close, but it's not noticeable at all on either of my DIncs.
I charged mine through the USB cable plugged into my laptop. Waited till the green light(Came at 66%, took about an hour wasn't really paying attention), turned phone off, continued charging both until green light again which took about another hour, probably less.
Now 88%, 7 hours standby, 30 mins uptime including installing gingerbread keyboard, playing with keyboard, sending texts and taking/sending picture.
