So far I don't have any issues with the ones I have. But now I only run .7ohm builds.
I just got a few to try, I still have my Sony VTC5. But vie had zero issues with the eFest 35amp while testing them out with a .7ohm build. Battery duration is decent as well.
i noticed a good battery life as well. it could easally last me into the next day
Well, there's a strong possibility that this battery actually has only a 20 amp continuous discharge rate rather than the advertised 35 amp rating that Efest claims.
An independent reviewer of batteries removed the purple wrapping and found a LG18650HE2 battery cell. LG states that battery is only a 20 amp battery. So, who you gonna believe? The original manufacturer of the cell or the company who is just rebranding it, and has a past history of exaggerating their battery specifications?
I find this disconcerting, as the people buying this battery expecting 35 amps for extreme sub-ohm vaping are only getting a 20 amp battery.

The purple "Efest 18650 2100mAh 30A" are rewrapped Sony US18650VTC4. Again, quoting Dampfakkus.de:

wow that very ballsy. how do they avoid lawsuites doing that?
There is no overseeing agency which governs the authenticity of battery specifications. A manufacturer can list whatever specifications they like. Most companies are pretty truthful of their specs, if they list them at all. What is happening with Efest, is they are listing what is actually the "pulse" rating as the "amp rating"; the "continuous" rating is the standard spec when comparing batteries from one brand to another. The pulse rating is typically much higher than the continuous rating. Efest has had a history of exaggerating their battery's specs in the past. I consider this rather deceiving.

very true. this is my first battery. as soon as i have a better finalcial stability im definatly gonna go pick up some sonys.
I have problem with efest imr 35A. This time I charge using intelicharge Chinese made for about 6 hours. The indicator change from red to green after 7 hours and thinking that fully charge. But surprisingly after insert into my sigelei, it doesn't fire it up. I've checked with multimeter and shows 0.3v.
Is there anyway how to revive the imr battery? I've use it for about 4 times.

Did you actually mean 0.3 volts, or 3.0 volts? What setting did you use for your voltage meter?
A battery with 3.0 volts should charge up to 4.2 volts with any decent quality charger. If it only has 0.3 volts that's a dead battery.

Yes, I guest the battery dead after recharge using stupidicharger that claim intellicharger.
EH IMR 18650, 30amp, 1600mAh, Flat Top, is from a reputable company. Also have other choices with more mah etc...
I've been using (2) Effest purple 35 amp batteries for 2 months now. I usually have a .18-.20 ohm dual build setup. With the amp limit being 20 amp you can run it at .21 ohms. From what I've seen, cloud contest and build are around .20 ohms now with ppl just doing low builds for personal reason. I perfer a .20 build on my dripper. And with my russian 91% I run a .6-.7 ohm build that has the battery lasting most of the day. Probably picking up some sony vtc's later for comparison. My friends run sony batteries and I've use there's not that big of a difference to me. Never had a warm battery!
