Battery reading fluctuates

[AvaOrchid]

Okay so I did look this up and it appears that other people have mentioned this specifically with sigelei mods but I didn't see any that were more recent. I look at my mod to see what my batteries charge looks like to see if I need to go ahead and change batteries and I swear to God the thing starts jumping around as though the batteries are charging themselves and then going back to the 40%. Apparently that's a problem that the mods have and isn't something to be concerned about but it freaked me the heck out. They're doing just fine now that they're in their external charger thingy but I just want to make sure that that's not a sign of something going wrong with the batteries that it's just my mod being weird I've checked the connections and everything to make sure it was clean and that the batteries were fine and not dented or unwrapped and everything looks good. I just need some assurance that the batteries were not like failing or that a regulated mod would shut itself off if batteries were jumping around like crazy in reality if that's even possible
For clarification it was doing this when I was not firing it

Sounds to me like it's just the mod having an issue if your battery chargers aren't exhibiting this problem. I wouldn't worry much if you've done some research on your mods and it appears to be an issue for other people as well.

But I don't have much experience with regulated mods (I use them, but have only used two specific mods and never seen an issue like this) so maybe someone else will be able to shine a brighter light on this.

Thank you for your reply. It's so nice to have a forum for these sort of things to be able to draw on people's experience because when I searched on Google the absolute BS that came up was astounding.

Haha, yeah. It's good you've found ECF and that you're looking into this, because while I'm pretty confident this isn't a dangerous issue, it could be - battery safety is of utmost importance, so any issue at all needs to be investigated carefully.

By the way, do you have any other mods that don't have this issue? The more sources you can check those battery readings with, the better.

That's exactly what I plan to do since they're acting just fine in the charger I figure I'll give him a little bit of a charge and then pop them in something else just to see what they do. I have a feeling that it's been doing this and I just have never noticed. I know that you said that you prefer Mech Mods but you may have some insight on this anyhow at what point of discharge should you charge your batteries? I've been aiming at no less than 35% and preferably right around 40% but I just sort of picked those numbers out of the air

I actually do prefer regulated mods these days, but I was a mech-only user for over 3 years before I switched. As a mech user I tried to charge my batteries when they were around 3.7 volts, mostly because then I'd get a better hit.

I'm not familiar with the degree to which it varies but I believe regulated mods often do vary in what they consider to be "0%" - correct me, someone, if I'm mistaken. So it's probably a bit more accurate to decide upon the voltage at which you're best recharging your batteries (you can tie that to whatever you mods indicates as the % left).

It's been a long time since I read all about this stuff. I know that Mooch has some great blogs on the subject. Off the top of my head, though, I doubt it matters very much because I doubt that your mods will let the battery get low enough to negatively affect their lifespan. Others here are far more knowledgeable on this than I am, though, so let's see what other input arrives later.

Personally, I tend to let my batteries get as low as 10-20% on my mod which is around 3.45ish volts before recharging. Never noticed an issue with degradation, etc, as opposed to when I used mechs and recharged around 3.7 volts.

My Sigelei's and some others do that while firing.
I believe it's reading the voltage drop/sag, as it's firing.
They do stop moving after being fired tho.

 

[DavidOck]

Agree with Sloth, likely just how the mod reads the voltage, and the then current state of charge.

There's a slight voltage drop when you apply power, normal. If the mod checks it then, it may look low. A second or so later, as the battery itself recovers from that tiny drop, it may rise enough for the mod to see it as a higher voltage than moments before, so the bar may bounce a little during that time, as the battery recovers.

Reasonable numbers for when to charge

I tootlepuff, and use almost exclusively RTAs of about 4 - 5 ml. I just swap batteries when I need to refill - so I get a full tank of both kinds of juice. Never paid much attention to how low the battery actually goes, although if one does go flat before the tank is empty, it's a target for recycling

Most regulated mods will cut off when the voltage drops to about 3.6, well within the safe range for the battery. There is some variation, probably due to the individual device's calibration though, but generally not a concern if you do vape it down that low.

I have used more than a few regulated mods and I’ve never seen this behavior in a mod either. I’ve never owned a Segeli mod though. I’ve had eciggie, lostvape, eleaf, geekvape, and kanger. None of them have done this thing you describe.

 

[DavidOck]

I suspect most don't read the voltage that precisely, but I've seen it a couple times, can't remember which mods though.

IF as suspected, it being an artifact of calibration and the precise voltage level of the battery, it's not going to show up much. You'd have to be watching at a time when the battery was right at the "break point".

 

[bombastinator]

There is another factor based on coil wire. Different types of coil wire will change resistance as they heat up. This is how TC mods measure temperature. It’s a derived value based on resistance change. This number generally goes up as the heat increases.

Here is just one of many describing the phenomenon with Sigelei's:
Does anyone have a Sigelai 20W?

Never owned a Segeli but all regulated devices reads battery voltage as the battery voltage sag comes into play during it being fired. How that gets displayed on the screen will be dependent on the design of the device. Through the use of Escribe we can see this in action with DNA devices, but yet the device does not display the voltage sag, nor does it display the voltage stabilizing after being fired. Perhaps there is a DNA Theme that can display this…not sure, never looked into it.

The Segeli may just be displaying real time voltage by showing the voltage sag, along with the voltage stabilizing after the device has been fired.

Quote from thread:
"It's completely normal for the voltage reading to drop while the fire button is pressed. It's just showing what your battery is doing under load. The static voltage reading is what the battery is putting out according to your set wattage and the Ω of you atty. The one that fluctuates slightly is the overall charge of your battery. Mine fluctuates a couple hundredths of a volt even when not firing."

Well now I'm a little bit more concerned it's definitely not the battery because my other set of batteries are doing it and neither set of batteries is doing it in my other mods. It's keeping the screen on so the screen will not time off. Even when I turn it off the battery readers coming up and showing the battery changing around its charge in both the little picture of a battery with the filled in area and the numerical percentages. So while it's still working I'm just really not happy with the idea of the screen being on 24/7 until I remove the batteries completely. What a shame I'm on a tight budget I'm trying to stock up and the product I've had for less than 2 months is making me really nervous to use. I don't really know how much the screen is going to eat away at the batteries but I feel like it's losing charge quicker than usual. It's just so frustrating and with all the stuff going on with the law knowing that I have a limited amount of time to get myself prepared and having already run through my miscellaneous spending money savings I'm almost to the point of giving up going back to smoking even though I've been off of it for 3 years and genuinely have zero desire for cigarettes. It's just so much stress with the limited time frame that no one even really can know and there's just no way to be prepared considering I only have at the very latest till May. I mean I know things break but I really anticipated having more than two months with this mod. I got away from the all in ones because for one who knows how long coils are going to be available so I wanted to be able to wrap my own and my all-in ones were only staying workable for like 4 months and that ticked me off because I'd have to buy dozens of them in order to have any sort of stockpile but at least I got four months off of those before the charging port would go bad this thing I only got two months. Well now that I vented my frustration does anyone have any advice on a really cheap basic mod I don't need it to go over 35 40 Watts I do need it to be usable with an RTA and I do need it to be regulated because I'm scared of mechanical mods. I want to say really cheap I mean really cheap...

I'm not really sure I understand most of the replies. When I look at the mod and the batteries are in the thing that shows you how much percentage you have left on your battery its literally moving all over the place constantly until I take the batteries out. It doesn't have seem to have anything to do with when it's being fired or when it's not it's just doing it constantly even when I turn it off with the five clicks it's still doing it it's just showing me a screen of a battery with the reading going all over the place. And it's keeping my screen completely on... it will not timeout. Maybe to give a better perspective I didn't fire it for 10 minutes and the battery still consistently kept moving around with the screen on I think the screen might be having a glitch but it's not doing it with any other factors just the battery. I guess I don't really understand how it even determines what amount the battery has been used or whatever so I'm utterly confused I just know it won't stop moving around and my screen can't shut off as long as it's doing that maybe I should try it with a different tank I don't really know how these things relate.

If your charger indicates 4 volts, and your device represents that as a percentage (lets say 80% for simplicity). Does the battery meter on your device go above 80% or below or both? And does it happen with use or just when the mod is just idle?

Moving constantly is not normal.
Sound like it's malfunctioning.

Well I took a video but I don't know how to do that or even if I can post that but I did do an experiment. I put the batteries back in with the atomizer unattached and it wasn't doing the fluctuation I put the atty back on it and it instantly started moving without being fired at all like the battery fluctuation started immediately. And then I fired it and the percentage went down from 96% to 88% and then once I stopped firing it it went right back up to the 96 percent even though the actual picture of the batteries is still moving around it's not like flying all the way to the bottom and then back up to full it's just moving a lil and constantly. The percentage number doesn't seem to move as much but it has a couple times. I feel like it's just tweaking out. My voltage is staying the same my ohms are the same it's just the picture of the batteries and occasionally the number with the percent next to it. When I fired it just now the voltage went from 2.86 volts to 2.82 and danced around between 2.80 + 2.85 while I was firing it. And it's doing the same thing no matter what tank I put on it. I wouldn't have a problem with it so much except it's going to keep my screen on permanently and I'm not sure how much power that uses but I feel like it probably uses some this device doesn't seem to have a way that I can turn that off
