Cosmo Communicator - Hardware / Re: Successfully replaced the battery with a third party one
« on: April 05, 2024, 12:11:24 pm »
Thanks for the hint with the batteries!
I successfully replaced my bloating battery with this one.
2 things I want to add:
- There is no need to keep the board "live" with connecting a PSU or auxilliary battery. The Cosmo will fully function after being left without a power supply for more than 48h
- You can desolder the small protective PCB of the replacement battery, clip the battery contacts a bit and directly solder the original PCB to the battery instead of the red and black wires. They have matching contact spacing
A small bit of kapton tape and the replacement looks exactly like the original, albeit a bit shorter.
