Battery for laptop Lenovo S10-2 IdeaPad

I bought a battery for my laptop Lenovo S10-2 IdealPad. Shipped quickly, reached about a month. Works without complaints, you can take.
Declared capacity - 5200mAh
The number of cells - 6.
Check for compliance do not know how, but the duration of the work does not cause suspicion.
For clarity, I insert only the video, because about the rest there is nothing more to add. There is no sound on the video, because shot with a camera that has a broken microphone.

Ps. The new one is therefore ready to listen to any constructive criticism.
PPS. The video is not published, for some reason, so I post a link to it:
