Recent ultrafire 880 mah 3.7v were actually testing at 380 - 390 mah, that's what drove mike to get the battery test equipment, I and others were seeing nowhere near the expected run time.
If you want to borrow a pair of powerizers to try, give me a shout. I have 3 pairs, no problem sending one set out for a while.
