Creative E3

Hi,


I have the Creative E3 that was not used for at least 1 year due to COVID.


The battery has bloated, and I changed the battery. However, after changing the battery (the protection board is unchanged), the unit gets very hot and I am not able to power on.



I then removed the battery, and just plug into a USB port. The whole thing just cannot power up.


Can someone advise what have I done wrongly?


Regards.
