Hardware Need help with something on my ps3 gamepad

[NoNAND]

Hii . I've always been a nintendo fan but i needed a gams controller for my pc. I got this ps3 CECHZC2U for just 25$
It looks good and feels good on my hands but it clearly is a fake because sometimes you have to mash the right dpad button to make it work. Other than that it works fine. I'm surprised it even connected wirelessly to mt galaxy s6.
The controllee did not come with an USB cable so i had to use a random one.
Now i'd like to know whether it will charge properly or not. I don't have a real ps3 so i had to connect it to my laptop. The 4 lights flash on and off.

Is this a sign that it is charging. How do i know when it fully charges?
I haven't paured it with my pc i just plugged it in

Yes, the four flashing lights mean it's charging, and iirc when they stop the gamepad is fully charged

Or the button is dirty, or the "connector" between buttons and board...

All 4 flashing slowly = off and charging (it requires being plugged into a compatible device to charge, btw)
1/2 flashing slowly = on and charging
1/2 flashing quickly = on battery, only some hours left
