I've bought many of these and charged them many times, in RC cars, flashlights etc. I put 3 of these in my Opus 3100 charger with a charge/discharge rate of 200mA (it can't work below that) they each measured 749,775,797 mAh. It's a 1/5.5C discharge rate (if you trust the 1100mAh class), so it's *plausible* that it's 1100mAh if you discharge at 1/10C. The capacity depends on the discharge rate. At high loads, the power must be reduced. This is the basis of the 101 battery science. So my test doesn't mean the capacitance is fake if you know what I'm talking about. They worked the same as the new Tenergy 1000mAh AAA cell I tested. So yes, I mean they work, I like them. I would buy more. i like the color It is nice that you can see from the side, even in the dark, which side is plus by the red edge of the label. Most other batteries are less convenient as you have to look up/down to see polarity. The capacity depends on the discharge rate. At high loads, the power must be reduced. This is the basis of the 101 battery science. So my test doesn't mean the capacitance is fake if you know what I'm talking about.
