Money down the drain

As it is useless to hold forth for hours on the quality of batteries when one does not have the hardware required to run tests that would give precise figures, I'll give you my example of use is concrete. I use these batteries for a mod for several actually.

In this case I tested them in a Z-max and Provari, info for connoisseurs. With the batteries I was using before they tired and they are failing to replace the (reputed Brand - 2300mAh I do not give voluntarily for we can not think that I am writing a comment for make advertising) I stood with 18650 between one and a half to two days.

I am a very big steam. With UltraFire 4000mAh (4000 mAh that's the biggest blague- I will not revive the controversy about the fact that these values ​​do not want to say anything anyway since we do not know the test stresses) it I took two a day the first 4 or 5 days of use.

From about the fifth day it is no longer possible to evaluate these batteries so they can be described as batteries. All charged up, they deliver an intensity that allows to properly run the mod for 5 to 10 minutes, after this one has the same effect as a valid but battery end of discharge.

In short, I highly recommend this purchase. There is no mystery finally, I will push the door open. All relatively expensive batteries are not good; but all those who are not are bad. There are areas where want to save money is to throw money down the drain. I return to safe values, admittedly a bit more expensive, but safer.
