My Bluetooth speaker (Tribit Maxsound Plus) would no longer charge after a more than 3 years. So I opened it with a screwdriver and soldering iron… Maybe there is a spare part.
After watching a few videos, I realized how easy it actually is. The protective grille can be opened with a screwdriver:
And then you can open the box with eight screws. (Yes, it got wet a few times. The white dirt is chalk).
You may then have to leverage a little with the screwdriver.
And already you can see the insides.
What was broken in my case?
Since the Tribit no longer charged, I first suspected the battery. After a few measurements on the battery and the circuit board, it turned out that the charging electronics must be defective. I could charge the battery with a 7.5V power supply and then everything worked again.
Except for the charging electronics. I still could not charge it via the USB socket. So I bought an 8V power supply and put the connectors of the battery and the connector on the PCB to the outside (At the place where the holding loop was). So I can run the speaker either in battery mode or in mains mode. I can also charge the battery in this way (ALWAYS measure the voltage to avoid overcharging the battery) without having to screw the box back on.
The loop just fit in:
Of course, the Tribit is no longer waterproof. But that’s better than throwing it away or leaving it in the drawer for years.
