for best performance.. change them as soon as the one in the charger goes green...
a fresh off charge battery produces better results than a half flat one..
they leave the charger at 4.2 volts.. during use they lose voltage.. when they hit around 2.7 volts the protection circuits blinks and switches them off..
its obvious a 4.2 volt battery works better than a 3 volt one.. so keep them in the upper voltage range whenever possible.. like when you are sat next to the charger..

ps... for those that like exact figures.. 4.2 volts is the high cut off point... 2.7 is the low one..
Wow Trog, that makes sense. I've noticed I've gotten more vapor from a batt fresh off the charger than one I had sitting for hours. I'll try that. Thankyou so much. You are all so helpful!
It's nice to have some place to ask such intelligent ppl who understand and know about these things.
