What will you have to face in the process of replacing the battery in a usb device?

Question

Electronics

There is a gamepad with a bad battery. I would like to replace it with a more capacious one.
How difficult is it? What to pay attention to?

As far as I understand, it will be necessary to replace the charge controller. Is it possible that the lack of its integration into the circuitry of the gamepad itself will become a problem?

Answer 1

The most difficult thing is to assemble it back :)
In general, until you unwind it and see the filling live - it is not known.
Well, or by model, find photos of the disassembled device. Perhaps there will be an ordinary battery on the wiring, which is glued somewhere. The task is to disconnect a couple of wires, pull out the old battery, take a new one, connect and fix it so that it doesn’t rattle.
A significantly more capacious battery will most likely not fit. You can not touch the charge controller, it will just take longer to charge (I doubt that there is something smart there that will see the difference between conventionally 400 mAh and 800 mAh).
In general - first disassemble, and there it will be seen what can be done.
Or find information on the model that is inside.

First, let's take a look at what we need. Then we search on Alik or in local stores. We learn that buying a new one will be 30% more expensive than repairing it. Buying a new gamepad.
