Disassembling my desktop soundbar to hopefully replace its dead battery to make it work again
This its BMS.
Its controls.
The brand name is Tylex XM18
The old battery, I will scavenge its BMS and the connector plug.
My desktop speaker which I enjoyed using for sometime until apparently its battery gave-up which actually needs replacement because otherwise it will not work. I thought at first when it was malfunctioning, i.e., getting disconnected that only the power connector was getting loose and or the power charger which it was connected from all the time was not delivering power, I was wrong.
It turned out after some research on its behavior that the battery was at fault, it needs replacement. But it is not as easy as it sounds because with my weak and flimsy hands and elbows with aching joints to make it worse, opening or disassembling this desktop speaker alone will not be that as easy as shown in the YouTube video which I watched a few times in order for me to rightly fix its issue.
Fixing this desktop speaker is simple but you needed some things to make it work again. I asked my father to remove the screws for me because my hands are weak enough to turn the Philips screw out and there were lots of them. However, prior to that I managed to pry-out out the metal screen after I was able to loosen the glue which was holding it from its sides, I took my time to do it.
After my father took off the metal screws I then proceeded to pry-out the part which holds the two speakers. Then I took out the volume knob, the small nut and washer which holds it and then its cover. I took off the plugs from its connectors so that I can take off the circuitry of the desktop speaker because I will have to take out the battery which is glued tight on its holder.
The battery assembly was glued shut but I managed to take the glue from one of its sides. I loosened the sides with my box cutter knife keeping in mind not puncture the battery or it will cause a fire or I might injure myself. It didn't worked for my to pry it our by lifting it from its ends.
I then banged the whole housing like a hammer trying to hopefully pop-out the dead battery from its holder but it won't budge. But I reckon that it is wrapped in plastic so I tried to strip the plastic on the top side of the battery and I proceeded to bang the case like a hammer, after a few strikes the battery finally got dislodged from its holder, I was happy about it.
I salvaged the BMS (Battery Management System) from the dead battery to hopefully use it again for my good battery which I bought a few years ago. I was ready to solder the BMS to my battery but I have no soldering iron and I have to buy it in order for me to fix my desktop speaker so that I can be able to use it again. I want to use it again because it is louder and better performing compared to the Xiaomi desktop speaker which I bought last year.
Upvoted! Thank you for supporting witness @jswit.
Despite feeling unwell, you persevered through the pain, meticulously removing the glue and disassembling the parts. I truly admire your perseverance. Sometimes, these "old buddies" really do sound better than new ones; their richness and depth of sound quality are unmatched by today's fast-paced consumer products. Once your soldering iron arrives, this speaker will be brand new! However, when soldering the batteries, always keep your hand steady, pay attention to heat dissipation, and safety should be the top priority.
