    TRUSTFIRE 18350 3.7V 1200MAH Rechargeable Lithium Batteries with Protection...
  

*by D***S on Reviewed in the United States on March 18, 2014*

I used these batteries in a ecig varible voltage Innokin SVD. They lasted less than 8 puffs before dying. My 183650 batts last for 4+ days with heavy usage. In conclusion  it can be safley said these are NOT recommended for ecig applications. Did not test in a flash light but the Trustfire 26650 batteries I do use in my lights work just fine.

    DO NOT BUY
  

*by A***S on Reviewed in the United States on July 3, 2014*

I got them for my cool fire II hookah vape, they didn't work. Needless to say I wouldn't recommend these batteries or any batteries ending in fire. This generally means they're made in china and of a poor quality. You would be better off going with an AW batteries.

### ⭐⭐⭐ 3.0 out of 5 stars







  
  
    Good batteries at first but only a few months in and one dies prematurely
  

*by B***D on Reviewed in the United States on March 29, 2013*

Like the title says. I bought these to go in my E-Cig Mod because my old ones started crapping out on me. For a couple months now they had been working well but now for whatever reason one of them just keeps dying out after just half a days use, whereas my the other will last up to a day and a half depending on how much I use my E-Cig.So yeah, that is a bit disappointing.
