Beolit 12 battery = Beolit 15 battery ?

The replacement battery for the Beolit 12 loudspeaker is not available any longer.

However, I have read on an battery vendor homepage that Beolit 12 and Beolit 15 use the identical battery.

Can someone please confirm if this is the case? Thank you very much! 

I don’t know for sure but by powers of deduction it might work

This is the battery for the BL15

If it’s the same as the one in your BL12 then it should work

Good morning Michael, thank you for posting your picture, I will open the Beolit 12 and verify.
