I just recently went out and bought a 1300 mah Ego-VV and the first time I used it, the battery guage had full bars. Then I used it until it said low, and I put it on the charger. I woke up the next morning and took it off the charger and saw that it had 1 bar. WTF? So I plugged it back into the charger and it said full with one bar on the battery guage. Has anybody else had this problem before? I don't know if this is common with this model or if I got a faulty model. Any help is greatly appreciated.
