IMR 18350 Flat Top 1200mAh 3.7V High Drain LiMn Demonfire Rechargeable Battery (2 Pieces)

These are pretty decent for small size batteries. They are comparable to an Aspire branded 18350 vape battery rated at 1350 mAh. Vaping at 15-23 watts and they last a decent amount of time for the size. I've put these through about 8-10 charge cycles each and no issues so far.

These batteries may not be compatible with all chargers. All I know is I have a functional charging unit for 18350 batteries and these batteries would not charge. Very disappointed. They may have been defective or outdated. These batteries are Made in China. I had to initiate a return.

A solid product delivered on time at a reasonable price. Not much more to say.

Great rechargeable batteries, good product, just a little shorter than similar batteries, by about 1mm.

I would like these batteries much better if the manufacturer reported honest specs, as it is now I don't really trust them. I purchased these batteries for vaping, and it seems to be the target audience. However like all ___fire batteries the specs they report are not to be trusted, as they violate principles of thermodynamics. There is only so much energy a battery can hold, if it is designed to release that energy safely at a higher rate, then the battery won't last as long. Therefore a battery can either have a high amp limit, or high mAh rating. The best 10.5 amp batteries in an 18350 size have around a 700 mAh rating, which these seem to perform around. However, to be safe I always assume these batteries have a much lower amp limit. I don't sub Ohm with these, and you shouldn't either. I've been using these batteries for about 3 months now, and while the performance has degraded, I feel I've gotten my moneys worth. If you need a cheap battery for any device these will get the job done, but be aware that the ratings reported are not reliable, and as with any battery, know what you're doing, because you and only you are responsible for your safety. If you don't follow proper battery safety procedures and take precautions, you're liable to end up with these exploding on you or starting a fire.

Batteries work fine but I got 1 with a dead cell out of 4 I purchased. The other three...the wrapper started peeling after about 2 months of use. Once the wrapper peels, it shorts the battery and it can't be used. Unfortunately I only have one left and it's about to shed the wrapper.

So Far an excellent choice for use on the SMOK Guardian E-Pipe mechanical mod recently purchased. The 1200mah for a high drain 18350 isn't seen that often either when searching for them on the web. The performance so far has been right up there! Give these a Grade A review.

My fiance uses these batteries for his E-Cig, and loves them. Says they are long lasting, and way better than other batteries he has tried.
