Creative MUVO 2 Battery Replacement

はじめに

I've bought the device in 2017 and it has served me well for quite some time. I really liked the connectivity (USB, Line-In, Bluetooth) and the possibility to simply pop in a micro-SD card and play music anywhere without the need for a second device. All while being sturdy and quite water resistant.
However, after 3 years, the battery barely lasts for 15 minutes, so I had to replace it.
Luckily This turned out to be rather simple

Li-Ion Batteries can catch fire and explode if they are being mishandled! (e.g. when they are short-circuited or physically damaged).
Unplug the battery from the circuit board. You might have to use a knife or some other tool to remove the glue that is on the connector.

Cut the cable of the battery. Take extra care not to short-circuit the two cables! cut each cable individually and make sure the cable ends on the battery are slightly different in length, so they can't accidentally touch each other.
Dispose of the battery according to your local regulations. Again: Be extra cautious as Lithium Batteries are known to easily explode and catch fire.
Also very carefully remove the protective outer foam-wrapping. we will reuse it later.

Get a new 18650 battery. I bought an expensive one from Panasonic. Be sure to spend some money in order to get a genuine one, and make sure to buy one that contains extra protection circuitry and solder tabs!
Sorry for the lack of pictures: Basically you have to improvise a bit. solder the cable with the plug somehow to the battery's solder tabs. Be sure to have the correct polarity! Also use plenty of sticky tape to protect everything from causing short circuits!
Finally, take the blue cushion-wrapping and somehow try to wrap it around the battery. Then try to attach the battery to the case using the black plastic brace and the two screws.
Carefully plug the battery-plug into the main circuit board and check that nothing starts to heat up or even cause smoke. In which case you have probably messed up.
Connect the speakers and switch the device on. If everything works, put everything back together.
Please note that your device is probably not IP66 anymore, but in my case the battery again lasts for many hours.
