EFEST IMR 18350 (V2) 800Mah Battery Short Vape Time

[ROM 1]

I am new to mod vaping so maybe it's just me and not the battery. I recently purchased 2 Efest IMR 18350 (v2) 800mah battery from EBAY for about $13, which I feel was a decent price. Anyway, I recently fully charged one of the batteries and measured the voltage on a fully charged battery. The multimeter read 4.18 volts, which I believe, based on what others have stated on this forum, to be normal. I placed the battery into my KTS mod and started vaping around 10pm. Oh by the way, the clearomizer that I'm using is your basic CE4 clearomizer with a 2ohm head. The KTS mod is straightforward without any variable volt or watt adjusting feature or LED display or indicator. It worked perfectly until 3am when I noticed a significant drop in the output of smoke being emitted from the mod. Although I was able to still vape, the vape smoke was very thin and almost invisible. It seemed that the battery was dying. I removed the battery from the mod and measured the volts, which read 3.5 volts. I would say that I am a heavy vaper and probably took about 35 -40 puffs for every hour. Being that this was the first charge from this battery, is the length of the vape time, which is 5 hours, sound reasonable to you guys? Is there a break in cycle for these IMR batteries, meaning that the more I use and recharge the battery the better the battery gets (longer vape time)? Is this normal or is it just me? If I want to increase the vape time, should I get a bigger battery with a higher mah rating? I feel that even my old school EGO batteries last longer than these IMR batteries. Please, any input would be greatly appreciated.

A 18350 will last me 2 hours on a good day. I chain vape. I get 4-5 hours on a 18650.

I had these batteries. They are pretty decent. 5 hours for a heavy vaper sounds good. The actual capacity of the v2 reds, is around 730 mAh, which is not bad.

The larger the battery the more vape time you should get. My guess is that with a mech mod, increasing the resistance of the atomizer will yield longer vape times, but much weaker vapes, as you would be drawing less power. With a VV or VW device, dialing down the power does the same thing. Its a balance between vape intensity/battery run time.

I agree with the posters above. That whole 1 hour per 100mAh does not apply to me with these batteries and my setup.

I get around 2 hours of optimal vape time with a further hour of reduced performance with an Efest 18350.

(That's using it in a zmax mini with a 1.3 - 1.5ohm dual coil igo l at around 4 volts.)

I've always gotten abt 4 hours of vape time from my AW 18350 batteries. Generally speaking, the larger the battery, the higher the mah, the longer the vape time between charges. Obviously quality of batteries and vaping style come into play but a 2000 mah battery is going to give a longer vape time between charges then a 800 mah battery.

Yep, heavy vaper here, and 2 to 4 hours is what I get out of my 18350s... I have EH, eFest and AW batteries, found no discernible difference between them.

Agree with others comments above. mAh ratings are sort of dubious to begin with.

Manufacturers/vendors list whatever rating that they wish as far as I know, no set standards for this in the battery trade. Some are more realistic than others, and some manufacturers of lesser brands list an unrealistic and inflated high mAh rating just to push more sales (Trustfire, Ultrafire, etc).

The mAh rating is supposed to be based on using a 3.7v battery device. Using higher voltages than that would obviously lessen the battery time because of the increased demand on power.

I've always used the red AW IMR class of batteries exclusively in both my regulated and mech mods. When making a new order for batteries for my daughter's new mechanical mod for her birthday, I decided to go against my usual practice and try some Efests. I got two Efest 14500 IMR for my daughter's mod, and two Efest 18350 IMRs for myself.

Mine were added to my 18350 battery rotation. All was fine for about two weeks, as the Efests were performing as well as the AW's. However, after that point I began noticing a drop off in battery time with the Efests, and it got progressively worse. My daughter also brought up that her batteries were not lasting as long as when new.

I ended up getting her some new AW IMR 14500 batteries and told her not to use the Efests any longer. I did the same with my Efests. Did I get a bad batch? Who knows, but I found it interesting that the same thing happened with two sizes of batteries. Efests did not make a favorable impression on me. These two sizes were both charged on Nitecore Intellichargers and purchased from RTD Vapor, a trusted vendor, BTW. Just my personal experience shared.

According to your post it seems well within expectations. 5 hours Heavy Vaping = less recovery time.
Even on an average day an 800 will only last me 3.5-4hrs

I truly thank each and everyone of you for responding so quickly and with so much great information regarding these Efest Batteries that I purchased. I thought I bought some bad batteries, but after reading your posts and what you've experienced with these same batteries, these batteries are performing normally.

WOW! I thought I was bad, I can get 7 hrs 6 1/2 with an 18490

 

[toughguitar]

I get about 2-3 hours out of an 18350. Great for stealth mode when on the go. I'll carry an extra if needed.

 

[bluehaze013]

If im at work an 18350 will last me 7-8 hours easy because im keeping busy not vaping so much but if i'm sitting around the house being bored I can kill an 18350 in 2-3 hours easy lol

A lot depends on whether using SR or LR delivery devices, and VV or no VV, and your "style" of vaping, but normal vaper times "technically" are supposed to be :

14500 @ 600 about 3-4 hours (more like 2 for me)
18350 @800mah= aprox 5-6 hours vape time (more like 3 for me)
18490 @ 1100 about 7 hours (more like 4-5 for me)
18650 @ 1600 about 11+ hours (depends)

I have NEVER gotten 7 hours on an AW 18490 but I use 1.7ohm cartos

I get all day on a 18350 900mah icr and that's chain vaping all day. I'm also just using standard ohm tanks. 2.0-2.8. Why such a huge discrepancy?

I had a zmax mini with the same type of battery and would easily get 2 days out of it and feeling like I vaped all day. At the same time my brother in law and drain a 2200mah 18650 in a single day.

The discrepancy is our definition of chain vaping is much different then theirs.
