uxcell Power Supply DC 3.7V 300mAh 502530 Li-ion Rechargeable Lithium Polymer Li-Po Battery

Battery is working great for me.I replaced the dying battery in my headphones.Although the dimensions of this battery aren't an exact match for the original, this battery works great in my Modal bluetooth headphones (a Best Buy model).Original battery had markings for size: 462430. I could not find a battery with this exact size.This battery is 502530, so 5.0 mm thick instead of 4.6mm.However it fit in the case no problem. Same voltage and capacity.NOTE - my headphones required soldering of the battery leads. Simple enough to trim off the connector thatcame with this battery.

Worked great in my Skycaddie watch.
