Li-Ion Batteries - THE TRUTH

[Keef]

P4CO if you have a battery that is good for say 1000 full re-charges then it should be good for 2000 half charges and so on.

But remember these little batteries are being hammered with the constant charging and discharging.
The mAh starts to drop off pretty quickly.
You will notice in the first week they give good vapour for a much longer period of time than they will in the following weeks.
They will also take longer to charge when new, once they start showing fully charged after a much shorter period it is time to replace them.

Thanks Keef,

So, better not to charge unless it's necessary

I don't think Keef is saying that.

See:

Welcome to Battery University
How to prolong lithium-based batteries

eg.:

"Avoid frequent full discharges because this puts additional strain on the battery. Several partial discharges with frequent recharges are better for lithium-ion than one deep one. Recharging a partially charged lithium-ion does not cause harm because there is no memory. (In this respect, lithium-ion differs from nickel-based batteries.) Short battery life in a laptop is mainly cause by heat rather than charge / discharge patterns."

Why are they not packing all their batteries with the new lithium-ion ?
LiFePO4
LiFePO4 Li-Ion batteries:


Rechargeable LiFePO4 3.0V 750mAhBattery
Life cycle: 2000 times (Traditional Li-ion: 500 times)
Never explode or catch fir
Capacity: 750 mAh
Maximum discharging rate:< 550 mA
Maximum charge current: <550 mA
Cell's dimension: 17mm Dia. x 34.5mm H.
Weight: 0.6 oz (18 grams).

You will be hard pushed to over discharge an e-cig battery with the atomiser.

That said it is still better not to continuously run the battery down until there is no vapour.

It is also better to keep them cool and not store them fully charged and unused for long periods.

Bummer, I have three dogs. Would have been kinda nice to have some batteries around to catch fir.

Thanks Kent,

I just got the 510, the manual says that I should give each batteries an initial 8 hours charge, I didn't do it, I just put it on the charger and when the light went green I started using it... it last for about 20 minutes or so... then I recharge it for 3 hours.

The manual says that it must be charged for 1 hour no matter what the light says, so I supposed the red/green light doesn't do much....

(silly question: are we sure that this batteries are lithium and not nickel?)

I'm charging one battery right now, I'm playing close attention to it, just to see when the green light goes on, if it goes on at the same time, then the charger must have a type of timer or something like that... anyways I just noticed that about ~15 minutes charging the red light started to blink one time to green (it's a really short blink red-green-red) every ~10 seconds!

Is this normal? maybe the charger is checking the battery charge? It's close to 20 minutes complete an hour in the charger and the light is still red... should I wait for the hour? or remove it when it goes green?

How long do you charge 510 batteries? 1 hour? 3?

I don't know about anyone else, but it takes 2 hours to recharge for my 510 batteries.. I can do it by clockwork... About the blinking red light, that is normal, mine does it all the time.. Remember to make sure you are screwing in the battery tightly when you recharge it, because I went to charge one the other day, thought it was tight enough, then after awhile the green light went on, thought it was fully charged, and it was dead.. I guessed that the battery was dead, but decided to recharge again making sure it was tight, after 2 hours it was fully charged and a.o.k.

~Now I'm out of breathe since I said that basically all of that in one long sentance *LOL*~

I'm guessing you have the corded usb charger. That's the red/green blinking light - stupid idea - should be either red or green - but it still works. Once you see green (even though blinking red) the battery is charged. As far as time goes, mine charge off my monitor usb ports and take about an hour. The charging cycle is not based on time, it monitors the actual charge and indicates when that charge is reached.

And they're lithion ion not nickel.

Well I have the charged that came with the kit, the manual says it's usb but it has nothing to do with usb as far as I can tell, it's just the charger and a really small power cord to plug it into the wall outlet, it also have a small jack on the side for 12v input (for car adapter, but there's no car adapter on the kit)

The thing is that I'm not really sure that this charger is really monitoring the battery or not, I mean the first time I charge it it went green in about 30 minutes or so... but it only gave me like 10 puffs... Then I charge the other one for 3 hours without caring about the green light and it last from 6pm to 1am.

But now I know that it takes around 2 hours to charge, so if I got a green light i will wait for at least one hour, after one hour on the charger if the light goes green i will unplugged it... this makes sense right?
