Are you sure about that? This goes against everything I have learned about Lithium batteries. They don't have memory. They don't develop "cycles," and really don't like to be fully discharged--letting them fully discharge is actually harmful.

Top em off early and top em off often. :)

It will keep them happy and will prolong their lifespan.

Ask Ars: What is the best way to use a Li-ion battery? | Ars Technica

Check the Battery University also...

A partial discharge reduces stress and prolongs battery life. See Table 2...

How to Prolong Lithium-based Batteries - Battery University

If you choose to not take my advice, that is perfectly fine. I have been working with batteries of this chemistry for many many years, and know from personal experience how they behave. I have also had nothing but success using my methods, as well as all my loved ones.

You are right, a fully discharged battery is not good. But, these devices have a built in "low voltage cutoff," usually hovering around 3.7. Therefore, no matter what you do, you will not be able to over discharge your battery to where it would be effected negatively or rendered useless. Topping them off early and often is a recipe for disaster.

You can throw all the facts at me you want, I am just stating my tried and true experience with my years of working with battery chemistry in hopes to help others extend the life of their batteries.

Just like op22222 said about his laptop and letting it fully discharge before charging when he got it, look what he said about his results. I do not get on here to spread rumors or tell stories, I get on this forum to spread quality knowledge and experience. Take my advice or not, those who do will see promising results.

From one good hearted person to another.

No disrespect intended toward anyone who believes they fully understand lithium/lipo battery technology, but I've read far toooo much conflicting info from supposed experts on batt tech that I've completely given up trying to figure out who to believe anymore.

So I just run my batteries till the over-dicharge protection shuts it off or near to shut-off, then with no topper and the Istick turned off, I charge it till full and the over-charge protect shuts it off.
And so far after a month with 2 Istick and vaping about 2 mls a day on 1.8 - 2 ohm coils at 3.4 - 3.6 Eleaf volts, I get between 3 - 4 days of vaping on each Istick before all bars on the battery icon are gone or the icon is flashing.

You learn something new every day here. I always thought that the old nickel cadmium were the last generation of rechargeable batteries to be susceptible to the "memory" thing. Nickel metal hydride came next I believe and the claim was no memory. That's been eons ago and so I thought the whole memory thing was a long forgotten malady of rechargeable batteries.

Ryan, I didn't mean to offend you. I have no professional experience with batteries so I go by what the Battery University folks are recommending. I provide links to trusted sources. I also try to remember what other experienced vapers taught me--our modders and battery experts are really smart--I read and listen and learn from them. You are of course free to disagree.

I've had several laptops--so did my kids and my husband. We never performed that procedure, nor were we advised to perform it. We never had any problems with battery life off the charger even after several years of use. Does it prove anything? :)

I am right there with you. Back when I got into working with this type of battery chemistry, there was all sorts of "good information" on the subject. However throughout the years I found out differently. Why study on something, when you can learn from your own experience. Don't get me wrong, you always want a certain amount of research into potentially dangerous subjects, but after that, go with your own methods and do what have proved to work for yourself and pass it along.

You are going about your charging habits perfectly, and you will always see good results in the lifespan of your little iStick.

I have been through way to much in life to be offended over something of this matter. :)

I simply wanted to pass along good knowledge from personal experience in hopes for some individuals out in this crazy world to try my advice, and see great results.

As far as your pc goes, I guess you will never know at this point. Perhaps maybe if you had properly broke in your battery, you would see even better results than what you are currently getting.

And to SthrnCelt, you are correct about the memory thing with newer chemistry. I use that term very loosely. It is more common sense. If you don't show your battery what it is like to go through a FULL cycle before it hits it's low voltage cutoff, than after so much time it adapts to this. Just think about it. Not saying that it is gonna ruin your "uptime" of your charge, but through my testing and experience, over time you will see a significant decrease not only in how long it goes between charges, but also how long the battery will last all together.

Like I said, take my advice or not, I am only here to spread personal knowledge from positive results. Not to argue my point, and get scientific.

Happy Vaping :vapor:

Katya....I am not an electrical engineer nor a chemist by any means. I am only stating a personal experience that I had and the results. Also, when I post things on this forum I try to be factual. I do not add things to them just to make them sound better or anything like that. I feel that I have learned a lot from ECF and I try to give back to the community if I can. You very well could be right about my laptop, or, maybe not, I don't really know? But, I have been practicing this method with new batteries ever since the laptop incident, and have been getting great results. Just stating the facts as I see them.

So I went and did some more research, and look what I found.

3: Allow partial discharges and avoid full ones (usually)
Unlike NiCad batteries, lithium-ion batteries do not have a charge memory. That means deep-discharge cycles are not required. In fact, it's better for the battery to use partial-discharge cycles.

There is one exception. Battery experts suggest that after 30 charges, you should allow lithium-ion batteries to almost completely discharge. Continuous partial discharges create a condition called digital memory, decreasing the accuracy of the device's power gauge. So let the battery discharge to the cut-off point and then recharge. The power gauge will be recalibrated.

I had no idea!

How cool is that? :D

You learn something new every day. :thumb:

Right. I'm here to help new vapers and myself. I don't like to argue--I want to learn. That's why I started my post with "Are you sure about that?" and not with "You don't know what you're talking about." :p

It's all good.

I was gonna see how people were getting along with the isticks but apparently the thread has been hijacked.

No, just skip back a few pages to where everyone was complaining about the Chinese Holiday and delivery times.
Then it was connector issues, and now it's just bickering about battery life, and manual dexterity. Not much different than any other ECF thread.
It is generally a good device, but this is what happens when the thread slows down.
FWIW, I love mine.

We vape about the same amount. I'll need to experiment with different juices to establish a pattern about the longevity of these coils.

One thing to note is that it is the original coil that came installed with it. I have replacment coils but have not had to use them yet. Also, from past experiences I have noticed that butterscotch and similar flavors shortened the life of my other attys.

This is why I said it is only crucial to fully discharge the battery for the first 4-5 charges in my original post! It develops the battery to know it's full extent from the get go, for those times when you do go all the way to cutoff. Only other thing I would change is the number 30 to 10. Then that information would be solid gold!

This is my last post about the battery life issues, since clearly talking about battery life on a battery thread is borderline hijacking! :blink:

Hope everyone had a spooky Halloween! :party:

Ok, Halloween night, I was standing on my front porch, happily vaping with my Nautilus mini + iStick and watching the steady stream of the little ones picking out their favorite candy from the bowl I put out. Then this cute little crab (that was her costume) walked up and said, "thank you for the KitKat mister. I like that .... you are smoking from, it's so shiny!"

A "...."?!!!! :blink:
