Help ID Lithium Battery

I'm trying to find a replacement for this rechargeable lithium battery that came out of a Bluetooth headphone adapter. It's a 3.6 V battery with wire leads.
Dimensions:
Length: 28mm
Width: 9mm
Thickness: 4mm
Can anyone point me to a part number, or generic type number?

Cells of that style are numbered by the dimensions; thickness in tenths of mm, width & length in mm.

That could make it a "401030", as a common size size?

Thanks. I figured there must be some kind of logic to the numbering system. That should make it easy to find something that will fit.
