The connection plug was not the same as my controller's. I had to cut the plug of the old battery and transfer it to the new one. That's how it worked. Before you get it, somehow find the type of battery that your controller uses, so you don't have the same problems as me.

You need to make a patent for the battery to attach to the circuit board. It shows that it is charging, the light on the dual shock turns on, but the controller still doesn't work. Another Chinese product.

It didn't work for me, but it turned out that the problem was with my controller, so first make sure that the battery is the issue and not the controller (I changed my rating from 1 star to 5 because I was unfair to the product)
