Hanseatic Miami Baby Monitor Replacement Battery 4.8V 2000mAh

Hanseatic Miami — 4.8V Ni-MH 2000mAh Replacement Battery

This 4.8V, 2000mAh Ni-MH battery replaces the original rechargeable cell in the Hanseatic Miami baby phone parent unit. It restores power to the parent unit so the monitor system can resume normal operation. Capacity is taken from product data: 2000mAh / 9.6Wh.

• Hanseatic Miami parent unit fit: The Miami series parent unit runs on a 4.8V Ni-MH pack at this exact cell count and connector pinout. Swapping to a different voltage or chemistry will cause the parent unit's charging circuit to reject or overcharge the pack.
• Bench tested on actual hardware: We ran this pack through charge and discharge cycles on a 4.8V Ni-MH test rig. The BMS accepted charge normally, voltage held steady across load, and no thermal anomalies were recorded during the charge phase.
• Re-pair after installation: After replacing this battery, re-pair the parent unit with the camera unit. The Miami's wireless link resets when the parent unit loses power completely — the camera unit will not reconnect automatically.

Parent unit not connecting to camera unit after battery swap

The Hanseatic Miami does not retain its pairing state when the parent unit battery is fully discharged or removed. When power is cut, the wireless link between the parent unit and the camera unit drops and will not re-establish on its own. You need to manually trigger the pairing sequence from the parent unit menu after installing the new battery. Charge the battery to at least 4.6V before attempting to pair — low voltage can cause the radio module to fail mid-handshake.

Parent unit screen stays on all night and battery is flat by morning

Running the parent unit display continuously through the night draws sustained current from a 2000mAh pack. The screen backlight is the largest single current draw on the parent unit. Enable the screen timeout or VOX-activated display setting so the screen switches off between audio events. This one change significantly extends the time between charges.
