Anyone not charged the first time for 12hrs?

[Myk]

I've never used Lithium Ion before so I was reading about them and came across this,

[FONT=Verdana, Arial, Helvetica, sans-serif] Lithium-ion is a very clean system and does not need priming as nickel-based batteries do. The 1st charge is no different to the 5th or the 50th charge. Stickers instructing to charge the battery for 8 hours or more for the first time may be a leftover from the nickel battery days. [/FONT]

Charging lithium-ion batteries

Sounds like if 4hrs is good for the 2nd charge it would be good for the first charge.

It also says they don't accept a trickle charge and if they did it would be bad.
When these chargers go green are they putting anything out? I know my Nimh charger lets the batteries get cold once it goes green.

I did charge for 12 (or was it 8?) hours and my batteries are going strong after some 7 weeks of nonstop use,. so I think there might be something in that. Batteries are said to die much sooner...

 

[GabbyD]

I didn't. And I've also wondered if those chargers are doing anything once the light goes green. I've never understood where the 12 hours and ignore the light info came from.

 

[Frankie]

I believe it came from the manufacturer.

 

[Myk]

The manufacturer says 8 hours for the first charge.
But if that means the charger is trickling once the light goes green it would be bad for the batteries to over charge them according to the above link.
At least that's how I read it, maybe someone who's more of a battery tech would read it differently.

I wonder if setting the batteries to charge and then having them trickle until you can get around to unplugging them is why some seem to die early (when that death isn't attributed to the switch).

I routinely leave my batts plugged in overnight.

I've been BAD with batteries. I've short-charged them, left them on chargers over the weekend, exposed them to cold/freezing temps, and generally been a poster child for "Assault on Batteries". I've never had any issues beyond switch probs, which are often (though not always) resolved with banging them repeatedly on my desk.

I've noticed they last longer on a charge if I don't pull them off immediately after the light goes green, but I think we may be overstressing the importance of initial charge. But hey, it's better safe than sorry since it's just a one time thing.

Overcharging shouldn't be an issue as they are supposedly protected cells, which shouldn't be affected.

On a related note, the above post says that Lithium batts don't need "priming", but I'm pretty sure I read the mini-fogger batts should be charged for 4 hours, used for 20 min, then charged the final hour (initial cycle only). Is this more battery misinformation?

Where do you hang them? I thoughts batts were nocturnal. Is that why you plug them in?

And there you are. One rodent talkin to another. ;~)

Good question wise one. If they say you can, trickling shouldn't hurt unless they want to make more money by killing the dang thing.

Take my cell phone. The guy said it can stay plugged in all night so it gets the trickle and lasts a little longer. That was 2 years this coming March and I still have the same battery. I just don't use it that much now that my mom passed so I unplug it when it says charged. Or if I fall asleep, I don't worry.

This would be a good question for Einstein.

I got a new battery yesterday but I could'nt wait the 12 hours so I just started vaping immedietly. I left it charging overnight tho.

It seems to be working a lot better than yesterday, but thats not surprising.

I think this whole longer initial charge thing is a myth.

The first 6 901 batteries I bought were charged for no more than three hours. One of those is now 3 months old, is in daily use and is still going strong (another 3 month old one has died, tho).

THe last two I bought were put through the 12 hour charge routine. No difference in performance at all, though they might yet prove to have a longer lifespan.

I strongly believe that is the case. I've never done it. It sounds like a hangup from the old days with ni-cad batteries with their memory effect and so on.

My understanding of LiIon batteries is limited, but they shouldn't really be too susceptible to this. Some have circuitry which monitors battery level independently of manufacturer specifications on what the voltage should be at different charge states, which calibrate themselves based on when they are completely emptied and completely full, thus not charging them the full time and not allowing them to fully discharge can initially decalibrate the level indications (but not harm the battery itself)

With most devices (though possibly not these ones) batteries are routinely fully charged and discharged in testing in the factory anyway.

I am currently cycling through 3 batteries. Two of them I initially charged for 12 hours, and one of them was only charged for 3 hours before I used it. I can not tell ANY difference between the three batteries and if you were to ask me which one had 12 hour initial charge neglect, I wouldn't be able to tell you. Now take in account that I have been using them for only about 1.5 weeks.....so who knows if there will be any long term affect. As far as I see it now though....the 12 hour charge is a myth.

I'm not sure about the whole 12 hour thing but it cant hurt so i advise all my customers to do it. The worst thing you can do to a li-po battery is drain all the juice out. That is why the have a voltage cut off(when it blinks 30 times).

That's the thing, if it's doing anything it can hurt by causing plating in the battery.
Best case scenario is that the cheap little chargers actually do shut down and it does nothing, worst case is they continue to trickle and damages the battery.

I use usb almost exclusively now. But until short ago, I was on batteries like everyone else. My batteries last anywhere between 3 and 6 months, some more, and a few duds inbetween too of course ('last' meaning: minimum of 1 hour power in them just before I throw them out; more, like 2 or 3 hours, in an earlier stage of course) (and I vape almost constantly so not a light user). I had 8 chargers in use at almost all times.

The way I charge the battery's? I only take them OFF the charger when I am going to use them; otherwise they simply stay on. With the charger on the power, just to be clear. Can be a whole night, a few days, or on occasion even a few weeks that they remain like that... and never seen this handling hurt them.
Do see that taking off a battery as soon as it turns green, versus leaving it on for at least a few hours after charger turns green, gives me a battery with a low load of power versus a battery with a considerbly larger load of power.

So whatever the books say... well... I've read the different theories and explanations too; but frankly I'm more interested in the practical results, and these are just mine... and I doubt I have 'special battery's' (or special chargers for that matter) - just like most anyone here would have I think (Oh one thing I always tried NOT to do: empty them completely - that does render them useless quickly I have found)

So well... don't know what anyone makes or wants to make out of this way of handling... but it worked well for me, so bar the usb coming along I wouldn't have changed that handling any, except the occasional testing/experimenting with a single one perhaps.

Never charged for 8+hours first charge and never will muahahahaha!!!!

 

[Keef]

Green = Go .

When the light in the charger turns green it is finished charging so I dont see any point leaving it there for 8 - 12 hrs on the first or any other charges.

The Chinese instructions I think are confusing the Lithium ion batteries with the Nickel ones.
The guy that wrote the booklet probably knew diddly about batteries.
He saw it written somewhere and copied it.

Same as the auto clean, they just copied it without question and decided it would be easier to programme it to trigger on every x amount of puffs.

I've never charged more than 6 hours, initially. I typically charge 4 hours on the batteries in my rotation - no problems with any of them so far and performance is good.

The risk you run when you leave 'em on the charger for extended periods is that if you have a faulty charger or defective battery control circuit an overcharge rate can cause Li-ion batteries to catch fire. You may remember the stories in the news about faulty laptop batteries exploding/burning due to defective charging circuitry. Best to err on the side of caution, I think. I know I never leave batteries charging when I'm out of the house or sleeping. Just my 2c.
