Philips Fidelio B5/12 Battery Holder

thingiverse

This is a replacement part for the battery case inside the detachable end speakers of the Philips Fidelio Soundbar B5/12. The batteries in these soundbars are known to swell up after some years. I had mine for 6 years before the batteries became so degraded that they did not last through an entire movie. The batteries are so swollen that it is hard to remove them from their original case, especially since they are fastened with some kind of double-sided tape, I did not dare to remove them.The case is designed to accommodate potential swelling in the future, which is why the walls are thin. To keep the battery in place and prevent vibration, I added pieces of a 4mm thick rubber training band.The replacement battery I used is: "CS-PFB500L" 7.4VDC 2500mAh.Keep in mind that there might be regional differences or similar soundbars that might use different batteries than what I used.
