ultrafire vs. trustfire

[Eyyitsclay]

i use two ultrafires for my 5v box mod. the ultrafires last a hell of a lot longer than the two trustfire. they are both 14500, 900mah bats. why is this? did i receive faulty bats?

Hard to say, in my experience TF is always a better choice than the UF.

You didn't provide links to the actual cells or said who you got them from.

i have those above,,the regular trustfire,aw high drain and ultra fire...
when i first got the ultra fires they were a major pain,,,would not hold a charge for very long till after about three cycles
mine are all 14500 also ,,now they all seem to hold charge about the same,,although i think the high drains aren't not doing as good as the others

I just purchaces 3 18500 3.7v 1600mAh Ultrafire batteries from Battery Junction. 2 were in shrink wraped and one of them was loose. The loose battery has some of the outer shell peeling off. I am an electronics guy (sort of) and just did a battery / Charger check because the 2 batteries that were in shrink wrap don't take a charge. I had them in the included Ultrafire charger overnight....

1. The loose (peeling) battery had a DCv of 3.9v and I have been using it since last night.
2. The 2 shrink wrapped batts that were in the charger have 0.0v/0.4v of charge
3. The (trickle) charger has a pole voltage of .84v which is normal as per factory spec.
4. I was sold 2 non-chargeable dead batteries.
5. Glad I can Vape, Regretting not buying AW Batteries.

Lesson: Buy what ECF Veterans Reccomend

BTW, 400 mAh < 900 mAh.

mAh = Milli Amp Hours....the more the better imo
