Shure BP 6001 DIS Receiver Compatible Battery 2.4V 1800mAh

Shure DIS Digital IR Receivers — 2.4V Ni-MH Replacement Battery (BP 6001)

This is a 2.4V 1800mAh Ni-MH battery for Shure DIS digital IR receivers. It replaces the original BP 6001 cell when the existing pack can no longer hold a full charge. These receivers are used in professional wireless infrared audio systems paired with microphones and headsets.

• DIS IR receiver compatibility: Shure's DIS digital IR receiver line shares a common 2.4V Ni-MH cell architecture across the range. The BP 6001 footprint, connector position, and voltage rail are consistent across these units, so one replacement cell fits the platform without adapters or modification.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on a DIS receiver, monitoring BMS response at full charge and during active IR signal processing. The cell reached rated capacity by the third cycle and held voltage across sustained receive loads.
• Ni-MH cycling on IR receivers: Unlike Li-ion packs, Ni-MH cells benefit from full charge-discharge cycles early in their life. Run the receiver until it signals low battery before recharging for the first three cycles — this lets the cell chemistry fully condition and reach its 1800mAh rated capacity.

Why a DIS receiver shows full charge but cuts out after short use

A freshly installed Ni-MH cell typically arrives at storage voltage — around 1.0–1.1V per cell. The receiver's charge indicator can read this as near-full before a proper charge cycle completes. Under active IR processing load, the cell voltage sags below the receiver's cutoff threshold quickly. Charge the new battery to full before the first use session and the receiver will behave as expected.

DIS receiver dropping signal or cutting out mid-session

Mid-session dropouts on a new cell are almost always a voltage sag event, not a range or interference problem. The IR receive circuitry and signal processing together draw enough current to pull a partially conditioned Ni-MH cell below the cutoff threshold. This is more common in the first five cycles before the cell reaches full capacity. After three full charge-discharge cycles, measure resting voltage — a healthy 2.4V pack should read 2.5–2.6V off charge.
