With this purchase, I clicked the wrong button faster than my brain reacted.I should have passed on this item.I knew that 2800mAh claimed capacity is unreal for 16340 (aka CR123A) Li-ion rechargeable battery.They are typically between 600mAh to 800mAh of real capacity.The non-rechargeable CR123A has much higher capacity, around 1500mAh, but they are single use only. Despite having lower capacity, rechargeable 16340 can deliver more amps with high drain models.When I did capacity test, 3 showed capacity below 300mAh and one refused to be graded.I set the current to 250miliamps for such a small battery.I am going to repeat this test again just to be sure.Perhaps I will get better results.Despite the false capacity claim, the batteries do work on my performance 16340 flashlights.I set them to the maximum brightness and they kept the brightness level for about 15 minutes before they fell down to medium level, and then to dim/low level, and stayed that way for about 1 hour.Glad that at least I can find some use with that 300mAh capacity.
