Top battery with super power and capacitance values ​​... but does not fit all

The battery itself, I'm 100% satisfied. He has more capacity than any other batteries of the type of building 18650 that I know. A bit disappointing but I found that in the product description is not that it is Flattop batteries. If the description was correct, I would have awarded full 5 stars. So I have now for the first time sort that my equipment can be operated with this battery. But the performance of this battery is very convincing. So I'm going to soon again just to buy for devices that only work with Button Top of the same model ... just with Button Top.
