Most battery chargers of the type used in e-cig kits with Lithium batteries will shut the charge voltage/current off once the LED changes to green. The LED is used to indicate that the chip inside has done its thing and aint agonnna do any more until it detects another battery in need of a jolt-o-juice. IOW, You can leave it on as long as you want - It won't charge any more than it already is once it reaches its preset trigger point. In the old days, with Nickel Cadmium batteries, cheap chargers were pretty primitive and would keep dumping current until you took it off. They got plenty warm too!

Modern stuff is pretty sophisticated and protection circuitry is nearly universal in both the chargers and the new battery designs.

Thanks! Great info! Is there something to be said about letting batteries drain to 0% before recharging?


I suggest putting one on the charger and vaping the other one immediately. The Li-Ion batteries are shipped with about a 90% charge, so you should be good to go.

Yep, that's exactly what I did :)

You don't actually drain them to 0%. Once they drop below a certain voltage (forget what it is...2.8v?) they shut themselves off. This is to prevent overdraining them. However, their ability to product vapor falls off quite a bit before that, so when they start getting anemic, throw them on the charger and grab a fresh one.

Also note that LiIo batteries have no "memory" issue, so it doesn't hurt them to recharge if they aren't fully drained. HTH

Thanks! Glad we have so many physicists on this forum!! :)

LOL! Heck, I'm just an engineer - we're not even supposed to be able spell physinteratist, ummm, physishmist...bah!... what you said up there. :facepalm: But thank you!

Antique Puffer is right on target though. There is a lot of misunderstanding associated with the care and feeding of batteries and such. The technology has come a long way since the days of Nickel Cadmium cells and primitive charging systems. The circuits have been designed to be nearly fool proof. Provided there are no manufacturing quality issues or just plain bad luck, you can do fiendish things with Lithium based batteries and they'll give you very reliable service. Just don't throw them down a flight of steel stairs or drop them in the toilet accidentally. (don't ask me how I know this)

I got my eGo kit today too! :toast:

I basically vaped one batt while the other charged, and then switched them over when it was done charging..

One thing about lithium-ion batts: they like a shallow charge more than a deep one. True, they don't have 'memory' like ni-cads, &c., but you'll experience an overall longer life-span if you put it on the charger well before it needs it.

FYI: this goes for laptops, too...
