Help me identify these lithium battery

I need help identifying capacity and brand of these cell. I got them from Zoltrix Z-Cyber Slot FX mp3 player but I didn’t see anything that showed capcity and voltage.

The information on the cell:
HW043450
20051123
ZI651EL

Thank you.

Pictures of the top, bottom, & a side are best, all of those pictures should have the battery next to a ruler for size comparison, that would be better than a generic code.

These smaller cells can be tricky (I am guessing it is a small Li-Po cell, 4x34x50mm?). The part number sometimes includes the dimensions. Can you post dimensions of the cell? That might help finding a suitable alternative.

I had to source one recently to repair a Sandisk Clip mp3 player. No protection circuit, 300mAh capacity.
