I've had a little problem with my Efest 2000 18650 battery and Trustfire charger. The red light never seems to go off. Its only the second time I've charged the battery. I left it charging for well over 12 hours. I had an Efest 18350 battery in the charger at the same time and this one went green light after a couple of hours.
I checked the 18650 in my vamo, after the 12 hours, and it was registering at 4.2v. There is a switch on the Trustfire charged with 3.6v and 3.0v, I have it set at 3.6v, the green light comes on straight away if I set it to 3.0v.
I have another 18650 is the charger now, which is also only on its second charge. If this one doesn't green light then I think its the charger at fault. If it does green light then it must be the other battery at fault. Unless these batteries can take over 12 hours to charge?
EDIT : The first time I charged the battery, straight from the shop, it went green light.
