I got my eGo on Thursday and the first full charge for each battery gave me a glorious 10 hours of vaping each. Second time through one battery didn't charge at all — the indicator light on the charger never turned green, but I'd read these take about 3 hours to charge fully, so after like 4 hours, I removed it from the charger but it was dead. The other battery, however, gave me 8 hours of use on it's second charge.
I charged the dud battery again and it seemed to be okay after about 3 hours on the charger (giving me about 8 hours of use). After that I lost track of which batt was which and had a couple normal cycles of use. Now, however, I'm back to problems. One battery wouldn't charge earlier and the other, on a full charge only gave me about 4 hours of use.
Obviously, I've got something bad here that needs exchanging, but I'm trying to pinpoint what. My suspicion at the moment is that the charger itself is bad and simply not charging correctly (or at all) sometimes. The indicator light is no good, but even when I time the charges for at least 3 hours, it's a coin toss whether a battery will work, work for a few minutes, a few hours or for several hours.
Anyone care to trouble shoot me? Or should I just send both batts and the charger back and start fresh?
