Short life of battery

[danibanani]

Hey folks!

My batteries suck. But maybe I'm vaping too much? They last at most 12 hours. My the end of the day I'm really toking my silver bullet to get a vape. This is my battery:

Your Online Electronic Cigarette Store

When my batteries first came I made sure they were completely charged before use. I only keep them on the charger until they are done charging, not all night while I'm sleeping. My mod is the silver bullet.

Any advice? I have 2 and have just ordered my third one.

Take care,
Dani

Good morning. Check out the post in my blog with the table quoted from Battery University, should be on the second page. There is a link to the information right from the source... if I wasn't mobile, I would just repost the info...

Basically though... we would need to know more information to know how well these batteries are working such as your atty resistance, how often you vape, etc...

I'd need to know what atomizer you're using to really know for sure, but I'd guess that the coils are just burning off energy faster than expected. Those batteries really aren't designed for heavy loads. Hopefully you're not sub-ohming with them.

More info if possible

As an anecdote to give you a basis for comparison, I'm using a vamo 35 watt most of the time, running around 20 watts usually on coils ranging from .9-2.0, some single and some dual, battery is a sony vtc3.

I carry a spare battery and by the end of the day i've usually swapped it out at least once. (especially if its my day off)

My gosh, I have no idea about any of those things. I know I'm an all-day vapor with the exception of being in school and my internship, so about 16 hours a day? Maybe not that much, but it's an estimate.

I called altsmoke about a different issue and Mason over there told me I was using an outdated atomizer. I'm waiting for my gentitank Mega to come any day now, maybe that will make a difference?

Where is your blog? I'd love to read it.

Thanks,
Dani

Dani,

By 'my blog', I just meant the one here on ECF. If you look under my avatar to the left... <--- You should see a link for the blog.

I haven't dealt with altsmoke, but I am not a fan of calling most vape equipment 'outdated', probably just meant it is an old design like a CE4 or such.

What device are you putting that battery in?

Either way... your run time is going to basically be based on the battery, battery connection quality, output power and/or atty resistance along with a little play caused by how often you vape.

 

[JimmyDB]

I see you said the silver bullet mod... I'll check that out. For some reason I had an issue being able to edit my last post.

I don't see anyone getting 12 hours run time out of any single battery on any PV any kind of problem at all. I'm not sure what your expectation is, but 12 hours is darned good in the big vaping picture.

Israfil,

I just emailed altsmoke to see what atomizer I'm using. I'll let you know as soon as I get the info.

Thanks,
Dani

So, 12 hours is to be expected? That makes me feel better. Thanks.

Take care,

Dani, yeah, if you are using the straight mechanical silver bullet with the LR510 atty they include in the starter kit (along with that battery), then you should be getting 1000+ five second puffs off of it. I'm basing that on it being a 1.5Ohm or greater atty as they suggest and that battery actually yielding something close to the 3100mAh as advertised.

With vaping, it's not how many hours you can have the device and vape... it's how many seconds you actually vape off of it. My average vape is a 5 second draw and the battery is resting the rest of the time, until I vape again. So, battery and atty aside, it's going to end up being about how long/often you use the device.

Either way, if the battery lasts from when you leave the comfort of recharging until you return, that sounds like a win. I would suggest having some sort of backup plan though, and it sounds like you already do.

JimmyDB,

Thanks for going out of your way to help me out and help me understand more about it. I really appreciate it. I didn't know if I had being buying crappy batteries or if this was to be expected. I vape all day long. I was a chain smoker, too. That darn oral fixation! Freud would have a blast.

Thanks and take care,
Dani

Dani, no one mentioned it, but that's a 3100mah lithium-ion unprotected cell. You really should be using lMR (lithium manganese) batteries. Li-on cells are prone to sudden meltdown in a high current situation. I know you aren't pushing them hard if you get 12 hours of vaping, but you'd be better off in terms of safety with the one below. I get about 8 hours on a 1.8 ohm coil out of the battery below and that's usually vaping it down to 3.5v level. You'd get much more than I just because I'm vaping it constantly and you apparently aren't hitting the vape that hard if you are getting 12 hours.

Thanks, DaveP. I will be putting those on my list to buy. I appreciate it.

The Efest 3100 is actually an IMR cell. There's a LOT of confusion on these frankly.. Now I don't want anyone to take what I'm about to say as a promotion for these particular cells, or a suggestion in any way. But... I do own a couple of these that I use occasionally depending on application. In typical E-fest style they are overrated and there's no doubt the 20A rating is a pulse rating. I'd guess that their continuous rating is probably 10-15A. I can tell you that I've personally (in a safe shielded environment) discharged one of these cells from 4.2v down to 2.8v at a continuous 10A draw. The battery wasn't even what I'd consider warm by that point. Even after giving it another 15 minutes or so to equalize the temp had not raised a whole lot above room temp. I then tested it at a 15A draw. It did heat up, but not abnormally so. It also ran from the entire 4.2v to 2.8v without any disastrous results. As I said, it got pretty warm at 15A, but nothing worse than I've done to any battery including my VTC4s and VTC5s when hitting them hard. The point is... If these were truly a 4A continuous rated battery with 6A pulse current as these tests claim, there is no chance I would have seen the results I did.

For what it's worth, that same cell I used for testing is still a cell I use. Would I ever use it as a "20A" battery like it's supposedly rated? No... But do I have any qualms about using it as a 10-15A battery? Not at all. And they do actually perform admirably in terms of battery life.

I've seen the reports of the german tests. I don't know to be honest. I almost wonder if the original cell he tested was somehow a fake. A cell with a 4A continuous rating would have pretty serious voltage sag at 10A. The cell I tested did have sag at 10A, but no more than I would expect from any other 10-15A rated cell.

Anyway, the point is, it is an IMR battery. (BTW... lithium batteries, lithium cobalt, lithium manganese, and the other variations and hybrids are lithium ion batteries.) I just don't want her to feel like she's walking around with a super unstable ready to blow any minute battery in her hand. The battery she has given the use she's using it for is just as safe as anything else. And given her desire for maximum battery life it's probably a pretty good choice.

So, my batteries are safe? I can scratch them off of my list?

Thank you SO much,
Dani

For what you are running they are absolutely safe. No worries at all! Now if you decide to throw a Stillaire on there with a dual coil .15 ohm build then you might have some issues.

From what I could find the Purple Efest 3100mah is an lMR cell. Everywhere I search, the black and silver Efest 3100mah is described as a Li-ion protected cell. Personally, I'd choose the purple Efest lmr 3100mah 20A battery.

Im wondering now.... I have a high powered flashlight... burns through a 18650 in about an hour. . Ill have to check the specs on those batteries see if my mod can run them. Never fear ill check the specs before I throw them in

Good call. I didn't even know they made another 3100. I assumed she was talking about the purple one. If it's the black and silver one you have, then it would be much better to get an imr cell. If it's the purple one then you are fine.

The 3100mah efest is 6amp continuous. Tested in Germany, verified by Baditude.
Never trust efest's advertised specs. They lie.
