fixing a NOCO GB50 - replacing buttons?

Like many I have an issue where the NOCO GB50 won't power on. It appears to be the buttons on the GB50. NOCO for whatever reason uses cheap parts that fail after just a few button presses.

Another ifixit showed the buttons here:

NOCO GB50 Power Button

My question is, how do I disconnect the battery from the circuit board? It seems to be hard soldered on. I understand I can't desolder/solder the buttons without taking off the battery first otherwise I could seriously damage the device. Any advice on this?

Thanks!

@ztwrhk3g6luccw6 double check that. The battery should only be held in place with some double sided tape. Use a small thin metal scraper and see if you can shim it in between and separate the battery from the board that way.

I found a good video here: https://www.youtube.com/watch?v=bwVRovIF...

It shows that the white connector should be removed and its safe to solder/desolder the button.

desoldered and added 3 new buttons. The NOCO charger works fine now. I also had to sand down the plastic case so the buttons had some room to move. Seems the button space is too short for this case. Now the buttons can toggle properly and the device works as expected. NOCO do better next time with yhour design.

The post you linked showed the battery connection to the board. It is not soldered, it is using a standard connector. Check the second picture in that post.

I just uploaded pictures from my board. The black connector is soldered to the board (back of board) as you can see in the picture.
