I have chosen this battery, because I have found that the previously purchased identical batteries from China cheap PRODUCTION, ever had almost none of the capacities indicated. In a few minutes they were empty. I run the batteries in flashlights: SecurityIng (40,00) with 4 batteries, then the Lorenz Revolution 3100 (130.00) with 3 batteries, the Armytek Wizard LED 1120 lumens with a battery and several others. All work with the 18650 batteries. Everywhere the same result: after a short operating time / battery / n are exhausted. In addition, the cheap China batteries have no protection circuitry against overload, low voltage, temperature. Since lithium-ion batteries can be very dangerous, they are like little bombs, security and real and true capacity to me is more important than that, what it print at the Chinese lies. Conclusion: buy low was again a flop. Too bad about the money thrown away! Well, I think that others who read this, are also willing to take 4 rather 15 per battery to invest, because in the end they come to the same conclusion. This here: ENERPOWER + even come from Germany. They are a bit thicker, but still fit well in the Armytek Wizard (75,00). But the Armytek flashlight also works with 2 batteries 123A depending 3Volt. Adjust tuts with these new batteries, but tight, anyway, the battery can be easily seen from the Armytek. These batteries are the driving Lorenz Revolution 3100! 106,50 for 6 batteries is of course a house number, admittedly, but against each matched all aspects, the OK is a delight, how much and how long the ENERPOWER + battery converts its capacity in light. In the SecurityIng and in the Lorenz 3100 these good little thicker batteries have sufficient clearance.
