They can take quite a while to charge, but you don't need to wait until they're fully charged to use them. They'll actually live longer (more charge cycles) if you don't fully discharge and charge them every time. It is, however, a good idea to charge them fully periodically and then check the voltage...they should be right around 4.2v fully charged...if a batt begins to vary from that it's time to take it out of service.
Also, if you happen to be unfamiliar with Li-ion batteries in general, it's a good idea to read up on them a bit...there are some risks with them that are good to know about. For example, it's a good idea not to charge them unattended, and to never leave them in a charger after they're fully charged...cheap chargers will often trickle charge batteries once they're "full", and with Li-ions trickle charging can and does make them burn, violently. Apologies if I'm telling you something you already are aware of...but better safe than sorry, as they say.

Your batteries are probably already good to go and ready to use right now. If your vape is kinda weak, or you use them and its starting to get weak, charge them. Your led will be red when charging and green when done. Takes around 4 hours for my 18650s to charge. Remove them from the charger when they are done.

With the charger that came in that kit... Your best bet is to leave one on the charger all night.. In a safe spot of course.

You'll be waiting a while. I have 2 of those chargers and charging my 18500's takes about all night, so I couldn't imagine the 18650. FYI, you should REALLY try the 4.8v NiMH batts in the bolt. Unbelievable.

unless you have an xtar/pila or similar charger i really would not leave the batteries on the charger while you sleep. Cheap chargers will continue to trickle charge a full battery and can ruin the battery or at worst cause them to explode. Is this outcome likely, no, but why expose yourself to the risk?

ok, i left the charger plugged in with the 18650 on it and after some time(i didn't keep tract of how long) the light started to blink slowly so i watched it for a few minutes. as i watched it the blinking got faster. i unplugged it and removed the battery.

so i would venture a guess that when the blinking starts the battery is done charging. it metered at 4.22 v.

it would be nice to have a little instruction sheet with any charger.( in this chargers case when light blinks the charging is done.) thank all for the assistance..

ok
