Direct replacement for HP Bluetooth headphones

This Cameron & Co DS-CS-HPB303SL battery fits HP Bluetooth Stereo Headphones using part numbers 365830-001, FA303A#AC3 or FA303A#AC3-NR. It supplies 3.7V and 500mAh capacity in a lithium-polymer cell. The pack measures 42.13 x 30.00 x 4.20 mm and arrives new with 100% OEM compatibility.

Simple two-wire installation frees the headset

The cell connects with the existing two-wire harness inside the ear cup, so no soldering or adapter board is required. Its slim 4.20 mm profile leaves the original cavity untouched and preserves the headband geometry. Swapping the pack restores wireless freedom without modifying the headset shell or adding external bulk.

Steady output through a full listening session

Lithium-polymer chemistry delivers a flat discharge curve at 3.7V, keeping volume and Bluetooth link stable from start to finish. The 1.85 Wh rating supports extended playback before the headset signals low power. Users who need multi-day runtime between charges or a higher-capacity cell will need a different solution.
