As far as I know, lithium ion batteries will not overcharge unless your charger is malfunctioning.

And I may be wrong about this, but if they are getting overcharged, you would know it because they will pop.
So I doubt you are overcharging them.

What kind of batteries are they, how long are they lasting, and how much juice do you go through in a day?
That will tell us if they are really not lasting as long as they should be.

I have been vaping for over a year....and have left my batteries on the chargers overnight ever since I started. I read on a thread when I started that today's batteries cannot be overcharged.....I have never had a problem with batteries not lasting as long as the stated amount of time....I have used 808s, egos, and epower batteries....all left on the charger overnight.

That has been my experience.

I use ego-T 1000 Mah. They simply deteriorate fast, at first one battery lasts me a whole day, even more, then less and less and less... by the end of the month a fully charged battery only lasts like 1 hour.
I thought about it because I know you are not supposed to do it with a laptop battery. If your laptop battery is fully charged, you are supposed to take it out, not leave it in, while a laptop is plugged in, or you'll be ruining it.
I thought it worked the same with e-cigs batteries.

My understanding is this...

It does not hurt the battery to leave it charging, as long as the charger is functioning properly.

But if the charger is not working right, and lets the battery overcharge, you have a problem
And if the battery protection circuit stops working right, and the battery happens to "get hosed" then you have a problem.

And when you have a problem the battery explodes/catches fire.

I am sure a battery expert will be along in due time, and can clarify these matters.
And more importantly, will correct me if I'm wrong.

I agree with most others. Sure you can leave them charging overnight, I even did tonight by accident. I usually take them off as soon as I see green. For extra safety it's just best not to. Its really rare something might happen with your battery, especially a protected battery like an eGo. However, freak accidents of that 1 in a million exist being able to keep a watchful eye in case that 1 becomes you will prevent damages from becoming bigger then they could. I dunno about you guys, but I sleep like a rock so I really try not to forget it on the charger!

My guess is that you can but you really shouldn't. As long as you don't make a habit of it it should OK.

*lol* sort of look at it like the gas tank analogy. If you let your car's gas tank get down below an 1/8 of a tank you have the chance of sucking up the muck & sediment in the bottom of the tank and ruining your fuel lines and fuel filter. But the gas tank doesn't know the concept of being broke till pay day :). It's not wise to do it, you're told not to.... but some times you do it anyway.

Always better to be safe than sorry.

The only real issue with modern batteries is internal damage, which can be catastrophic while charging or discharging. Since there is no way to easily tell if a battery has been damaged, I try not to leave any battery charging overnight unless I can't help it. Any time I know a battery has been dropped or overheated, I take it for a spin on the multimeter before charging or using it.

I try not to let mine charge overnight, sometimes I forget...but rarely. Even in the day when I am near them, I put my charger and batteries in a metal empty coffee can ( yes they still make metal coffee cans, Chock Full Of Nuts). I know it may seem like overkill but I have seen some bad battery pics here on ECF. *shivers*

If the charger is doing what it should be doing, it shouldn't hurt to leave a battery on the charger after it is fully chargered.

But...

Most e-Cig chargers are Mass-Produced with Questionable Quality Control.

The danger to me is not so much Shortening or Killing a battery. The danger is a Fire.

This forum has numerous threads about people Batteries Exploding and Chargers catching on Fire. Yes it is rare. And yes you are going to read posts where people say that they have never had a problem. But that Fact is it can and Does happen.

So if I was the OP, I would charge there batteries in a Metal or Glass Pan and I would never, Ever, EVER leave a battery charging when I went to sleep or have left the house.
