Hey all, I just stumbled across this thread as I am seriously thinking about buying a GLV. Just for the record, my Ultrafire charger would always show my AW 17670 batteries as fully charged suspiciously early in the charging cycle. When I put them in my PV, they fagged out quickly or did not work at all. I sent it back for a second charger which did the same thing. I was so frustrated at this point that I just threw the second one in the trash and bought a Pila charger which works flawlessly on the AW16760's.
In retrospect, I wonder if the Ultrafire chargers work better with safe chemistry batteries than AW protected batteries. Just a thought.
