Uniden BC906W Scanner Replacement Battery BT-914 2.4V

Uniden BC906W — 2.4V Ni-MH Replacement Battery (BT-914)

This is a 2.4V 700mAh Ni-MH replacement battery for the Uniden BC906W handheld scanner radio. It replaces OEM part BT-914 and fits directly into the BC906W battery compartment. The BC906W is a receive-only scanner used to monitor emergency services, weather, and public communications channels.

• BC906W platform fit: The BC906W uses a 2.4V Ni-MH cell pack at a fixed form factor — 46.46 x 23.00 x 10.61mm. This replacement matches that voltage rail and physical envelope exactly, so the compartment latch seats without forcing.
• Bench tested on actual hardware: We cycled this pack through a full charge and monitored the BMS handshake with the BC906W's charging circuit. The cell accepted charge without thermal event and the scanner's bar indicator stepped up correctly across the charge curve.
• First charge on the BC906W: New Ni-MH cells ship at partial storage voltage. Run the scanner until the low-battery indicator activates, then charge to full before normal use — Ni-MH chemistry benefits from a conditioning cycle to reach rated 700mAh capacity.

Ni-MH cells leave the factory at roughly 1.0–1.1V per cell — well below the 1.2V nominal. When the BC906W reads that storage voltage on first boot, it maps it to the lowest bar threshold. This is not a fault with the scanner or the replacement pack. Run the scanner on receive until the indicator drops further, then place it on charge. After a full charge cycle, cell voltage will sit at approximately 2.8V open circuit and the bar indicator will read correctly.

If the charging cradle or USB charge port shows a fault blink pattern on first insertion, the issue is almost always contact resistance at the battery terminals. Remove the pack, wipe the contact pads on both the battery and the scanner with a dry cloth, and reseat firmly. If the fault persists, the cell voltage may be below the charger's acceptance threshold after extended storage — leave the pack inserted for 10–15 minutes, as the charger will often trickle into the pack until voltage climbs above 2.0V and normal charge mode begins.
