AOR AR-DV10 Replacement Battery BP-10 7.4V 2000mAh

AOR AR-DV10 — 7.4V Li-ion Replacement Battery (BP-10)

The BP-10 is a 7.4V, 2000mAh lithium-ion battery for the AOR AR-DV10 handheld receiver. It slots into the AR-DV10's battery bay and connects via the same multi-pin contact strip as the original pack. Voltage and BMS parameters match the AR-DV10's power rail spec.

• AR-DV10 platform fit: The AR-DV10 runs a 7.4V nominal rail with a BMS that validates pack voltage before the radio powers on. This replacement carries the same voltage floor and charge termination thresholds, so the radio's protection circuit accepts it without throwing a fault.
• Bench tested on actual hardware: We cycled this pack through charge and full-draw discharge on a load tester set to the AR-DV10's typical current draw. The BMS held cutoff at the correct low-voltage threshold and did not trip during simulated scanning loads.
• First-insertion contact check: If the AR-DV10 does not power on after inserting this pack, remove it and wipe the gold contact pads on both the battery and the radio with a dry cloth. Storage voltage on a new cell can sit just below the radio's power-on threshold — a clean contact cycle lets the BMS handshake complete and the radio accept the pack.

The AR-DV10 reads pack charge state from cell voltage alone — it uses simple voltage-threshold bar steps, not a fuel gauge chip. A new BP-10 ships at storage voltage, typically around 3.7–3.8V per cell, which sits in the middle of the voltage range. The radio correctly reads this as partial charge and displays fewer bars. Run one full charge cycle in the dock first and all bars will appear.

This usually points to high contact resistance between the battery's gold pads and the radio's spring pins. Even a thin film of oxidation or debris raises impedance enough to cause a momentary voltage dip when the AR-DV10's processor spikes current during active scanning. The BMS reads the dip as a low-voltage event and trips. Clean both contact surfaces, reseat the pack firmly, and confirm resting voltage reads above 7.2V before powering on.
