Battery replacement? (Soldering, series of questions, detailed)
So my Marshall Mid Bluetooth headset stopped working abruptly today. It turns off immediately and will not charge. I’m assuming this means the battery has kicked the bucket.
I’m trying to see if it’s possible to replace the battery, but unfortunately there is almost nothing on the subject. The only source I could find is replacement battery for Marshall’s MID Bluetooth headphones? which was unfortunately left dormant before the important questions could be answered.
Therefore, I’m making this thread in the hopes that I can get an answer to the question: "How can one replace the battery on a Marshall Mid (bluetooth)?”
As I have no experience with soldering, I have a number of sub-questions to this topic just to make 100% sure that I’ve covered all my bases. I apologize for my lack of knowledge, but I just like to be as careful as possible. Also, please feel free to explain everything as in-depth as possible, as if I’m a five year old.
Above is a picture of the battery of a Marshall Mid (bluetooth). From the thread I linked, I understand the importance of correct dimensions and voltage, along with how to find these. I’ve looked around on the web and found this:
'''Would this battery work with the Marshall Mid?'''
I read in the other thread that the three wires are “negative”, “positive”, and “ground”. I kind of understand “positive” and “negative” (as all batteries have these), but I have no idea what “ground” is, and all the battery in the link tells me is that it’s got a “thermistor” (which some Googling did not help me understand in regards to this question).
Cette question est-elle utile ?
I’m having a strange problem guys. After a complete discharge of my marshall mids, i tried charging it, and it charged it 100%. But the phones stayed on for seconds, then it turned off. Tried 5 times and same results, it’s really strange… And now it won’t even turn on at all. When i press the power button, a red led blinks for half second. Now it doesnt even charge the battery. What can it be? Is there a possibility to buy a Marshall Mid Motherboard? (used a tester to test every wire and everything works fine. Also tried with another battery, and it didn't work)

@Dmitry Reznikov hello,
It's been quite a while so I can't remember all details 100%, but the tl;dr is that they did not get repaired.
I bought the battery that I linked to and got a friend who was experienced at soldering. We attempted to replace the battery of the Mids, but the new battery didn't work at all.
I don't know if it was an issue with the soldering or the battery. But I think it is the latter.
Good luck with your issue.
I have been used solution with PCB replacement posted earlier and seems it's really work
