Akku ersatz von Sony SRS BTX300

Die Batterie wurde ersetzt, lädt sich jedoch nicht auf oder startet nicht.

Obwohl es startet, wenn es an ein Netzteil angeschlossen ist, ist das Ladegerät nicht kaputt

Könntest du mir bitte weiter helfen?

eng. version:

The battery has been replaced but will not charge or will not start.

Although it starts up when plugged into a power adapter, the charger is not broken.

Could you please help me?

Hmm you could try a few things:

  • Disconnect and connect the batterie -> Observe the status LED if it charges (change colour or so…)

  • Meassure the voltage accross the battery (min 3.0V or more)

  • Check the connection between batterie and the PCB

Tahnk you for your answer.

The LED is becomming red as it is charging, and after a few seconds it turns of, like it is charged already. But when the power cord is disconnected, the speaker dies.

I will try to open it and check the connections between batteries and PCB, also measure the voltage of the batteries and keep you posted. Weird is that I bought two sets of batteries and it does the same with each one. Unforntunately, I do not have the old battery anymore, because I have dissasemble it because I tought it is not good anymore, but apparently the batteries work fine.

Thank you again :)
