Motorola MBP160 Replacement Battery BT183342 2.4V 700mAh

Motorola MBP160 / Comfort10 Series — 2.4V Ni-MH Replacement Battery (BT183342)

This is a 2.4V, 700mAh Ni-MH battery for the Motorola MBP160 baby monitor parent unit. It fits the MBP160, MBP160PU, Comfort10, and Comfort10PU. The OEM part numbers it replaces are BT183342 and BT283342.

• MBP160 and Comfort10 parent unit compatibility: Both the MBP160 and Comfort10 series share the same 2.4V Ni-MH cell format, connector pinout, and BMS handshake. One battery fits both lines because the parent unit hardware platform is identical across these models.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on an MBP160 parent unit. The BMS accepted the cell without error, charged to full voltage without cutoff trips, and held stable under the continuous audio receiver draw the parent unit sustains during monitoring.
• Wireless re-pair after swap: The MBP160 parent unit loses its link to the camera unit whenever power is fully interrupted. After fitting this battery, press and hold the Pair button on the camera unit, then confirm the link from the parent unit menu — the monitor will not resume audio transmission until this step is complete.

Why the MBP160 parent unit drains overnight during active monitoring

The parent unit runs its audio receiver and display continuously when screen timeout is disabled. That sustained draw hits the 700mAh cell hard across a full night. A Ni-MH cell at this capacity is not sized for overnight portable operation with the screen active — it is sized for portability within the home while the unit is periodically placed back on charge. Enable the screen timeout in the parent unit settings so the display cuts after inactivity, reducing draw to the audio receiver only.

Parent unit showing full bars but range drops immediately after battery swap

The radio transmitter in the parent unit is voltage-sensitive — it draws peak current during signal bursts, and a partially charged Ni-MH cell sags under that load. The unit may display full charge while the resting voltage is still low from a fresh install. Range will appear reduced until the cell completes its first full charge cycle. Put the parent unit on AC charge until the indicator shows full before using it wirelessly — this brings the cell to 2.8V fully charged and gives the radio transmitter its rated power headroom.
