Charger Assistance.

I've just gotten a VV box mod and I'm loving it. The batteries ,14500(s), died so I stuck them on the charger which is 1200mA and The red light, which indicates that the batteries are charging, turned green in maybe 15-30 minutes. So I think, "this can't be possible..." I put it into my device and they seem charged but weak. Again the light is green in 5 minutes. Does it just charge that fast? should I leave it on while they're green? (my intuition is no).

I've ego chargers go green too early and that usually meant the battery was screwed on a little tight. I turn it left until it turns green and then stop as soon as it is red. Since there are no threads on these batteries obviously. So I have no clue

Is it just that fast?

You need to get a multimeter, they have very cheap versions available at harbor freight, or a local hardware will have one as well, or maybe you can borrow one from a friend or family member. That way you can test your batteries and find out what is going on. Here is a site that can bea great tool when it comes to li-ion batts and most other batts as well.

Well, what batteries are you using, and what charger are you using? Sounds to me like something is very wrong, batteries simply do not charge in 5 minutes. Put a meter on those batteries. If they are already at 4.1-4.2v, they do not need charging, and that's the only way that what you are discribing would be normal.

That's one heck of a charger, seldom have I seen ones that charge at that high a rate, which in general is much too high for 14500s. Something in the 400 - 600mA range seems more appropriate.
