Battery not lasting & E-Liquid intake.

[Flawed]

Hi everybody. I'm new (just started two days ago) to EC's and have several questions to ask.

I bought 2 AW IMR 18650 2000 mAh and have been using it for two days. I noticed that I need to recharge often. I read online that we should recharge batteries when it reached 3.6 volt. I vape at 5.5 watts, wonder if that is draining the battery fast. I've read people chain vaping on a single battery for a whole day. Also if the charge is like what my battery has then sub-ohm vaping will probably last for just one puff. How is that possible? I expected this battery to last longer than that. Maybe I have a fake AW battery? I hope it's not. Can somebody enlighten me on how long a AW 18650 2000 mAh typically last?

Another question is about e-liquid intake. I've read people who used to smoke 1PAD only vape 1.5ml - 2.5ml. But I vape like 3ml in only half day. If I vape like I normally smoke then I would probably need 6ml. Haha and I am not even 1PAD smoker. Maybe around 0.5PAD a.k.a one pack two days.

My experiences are similar to yours. I read of people getting a day or more from an 18650 but that's not how it works for me, and I use at least 5ml per day. I doubt your batteries are phoney or dud, and I'm sure it's a matter of how long you hit the fire button for and how often you do it. Carry on as you are, I don't see a problem.

AW 18650's, the red ones at 2000mah, in my experience, were never that great at holding a charge for very long. A quick glance at its discharge rate curve seems to second this. It'll basically dump all the amps at once, run itself down to 3.8 to 3.7 volts pretty quickly, and then fall off altogether, needing a recharge to perform again. I ditched all my AW's and moved on to sony vtc4's and vtc5's and have had a much better experience.

In terms of liquid intake, I have, at one point, gone through 20mL in one day. Then again, I vaped all day on my cloudchasing build, a Tobh v2 Atty, with a ridiculous coil build at roughly 0.14 ohms, which is a really, really, really bad idea. So to each their own, and there is certainly no standard on either of these things, battery consumption or liquid consumption.

A word of caution however, as I have no idea how long your battery does last, and nor do I know exactly what your setup is. If you do have a DOA dud of a battery, it would be wise to chuck it (i mean recycle it) and replace them. Vaping on dud batteries does suck. Let me know how long your battery actually lasts, how you vape, and what your setup is before you chuck those batteries. It may be user error.

I have 4 18650 batteries. 2 AW IMR and 2 eFest IMR and get a solid day + out of all of them. All used in a Provari with Kayfun Lite + V2. I vape about 5-6 ML a day and have never had them not last a whole day +.

You still have plenty of vape time when the battery reaches 3.6 volts. You are charging way before you need to.

Without over discharging the said batteries, at what remaining resting voltage level do you suggest charging the said?

I'm a chain vaper if I'm at PC/TV and so I use much lower nicotine juices when I do - so its not about getting my nicotine hit,its just a nice habit for me, so I wouldn't worry about daily amount as its probably more about nicotine strength with amount

I can sometimes go through 10ml but its normally 4-6ml in a mix of nicotine strengths to suit what I'm doing and whilst you're at this early stage, don't worry too much about intake as you are doing well getting off the ciggies! You will settle into a routine as the weeks go on.

Oh, and ignore all that stuff about nicotine eliquid equating to a specific amount of cigarettes.... its not something that can be measured simply. You would know if you overdo things, just keep up your water/liquid intake as your body is flushing out toxins and if you dont have enough fluid you may get headaches from dehydration.

I do spend my life battery swapping but you soon get used to it, you are still forming a brand new habit to replace your smoking so its a massive learning curve but well done on taking that step!

Thanks everybody for answering my questions!

@amtseung : Sure I will jot down how long my batteries last for you. Gonna full charge them, fill full tank then test their endurance. I don't really have any fancy setup, vaping on a iTaste SVD at 5.5 watts. About how I vape, I have no idea... first time I tried no vapour was coming out. Then I tried slower draws and the vapour improved, but not very much.

@Shootist : Can you recommend when to charge my batteries? I'm scared about over-discharging them and causing them to die.

 

[amtseung]

certain death of one of these 18650's tends to happen when it drops below 3.2, at least from my experience.
I feel like I asked the wrong question, because when I asked how you vape, I intended to ask what your vaping habits were, like how often you take a drag and how long your drags are.
Sorry for the unclear question.

You are recharging your AW IMR batteries at the proper remaining level.

I recharge all of AW IMR 350, 490, and 650 batteries at some 3.6/3.7 volts, whether they are used in my ProVari Minis or my mech mods.

Your always better off going for high quality batteries like Sony V4 or V5.

How long of a draw has a lot to do with battery life, longer draws reduce battery life your get. Also higher voltage/wattage setting reduce battery life.

It becomes obvious that high wattage/voltage settings and long solid draws will result in less battery power adding chain vaping into the mix will also cause another reduction in battery life. It becomes a give or take issue. Passthrough device is an option that could overcome the battery life issue as long as you can get to electricity.

On the liquid try increasing your nicotine level about 2 mg, it should help.

So many e liquids mann

remember too that heat and humidity play a part in how efficient batteries perform. Being in Malaysia.... you have BOTH. Telling us you are at 5.5 watts, is helpful, but it only provides half of the puzzle... at what ohm's are your coils?

Ah okay no problem. My vaping habit is still linked to analogs. So I would say vape break every hour. How long? Hmm... every drag probably like 5 seconds.

I see. I went and got AW's because everybody on the internet says that's the best batteries. Even the instruction booklet that came with my SVD recommended AW so yeah... that's why I went and got them.

Is the Sony V4 or V5 the hybrid chemistry type?

It used to read 2.0 but after I cleaned the atomizer it increased to 2.1. No idea why... I probably didn't screw it tight enough.

 

[eratikmind]

AW IMR Batteries are some of the best batteries money cab buy.

I will use the Sony VTC batteries on certain mech mod builds. Most people never need the 30 amp max continuous discharge rate of the VTC.

Without over discharging the said batteries, at what remaining resting voltage level do you suggest charging the said?

I believe the SVD has battery over discharge protection, it won't fire once the battery has drained down to certain point. Usually that is around 3.3 volts (+/- .1 volt). So try using it until it doesn't fire anymore or until you see the battery get to around 3.3 or 3.2 volts. Then recharge all the way to 100%, 4.2 volts (which your charger will take care of. Turning off when the battery is fully charged).

True . . . But then again, I'm the type of person that does not wait for the "check oil" light to flash to change the oil, as well.

Is this safe?

Recharge empty batteries ( resting voltage below ~3.6V ) as soon as possible. Leaving LiIon batteries in discharged state will incur irreversible damage ( capacity / cycle loss )

So.... 5.5watts with a 2.1ohm coil means it needs to fire at 3.4volts to get that 5.5watt.... I believe the SVD does not have true step down, so there is where you are "wasting" some of your battery life. Because until the battery voltage actually drops to 3.4v it is firing at whatever voltage the battery has.

Wow I never knew it worked that way. Oh my I really need to learn more about using APVs. I'd thought that just because I went online and get a chart then put the volt and wattage in the green area it's good to go.

BTW when I first started I put the watt at 15watts. The whole thing heats up like crazy. Hurts my throat. Then I realized I've burned my atomizer. Stupidly went and try again on 6 volts. Same thing. Silly me! xD
