Compatible replacement battery

This lithium-polymer pack replaces the original power source in Babysense BBM01, BBM03, Bonoch BBM05 and HD S2 Video Baby Monitor units. It matches the factory specifications of 4000mAh capacity and 3.7V voltage. The 5-pin connector aligns with the original design for direct fitment. A fully decoded chip ensures the monitor recognises the cell immediately.

Upgrade from depleted original cells

The jump is worth it when the monitor no longer holds a charge through a full night or shuts down during nap checks. Swapping the worn cell restores the original runtime without modifying the device. The new pack arrives ready for the recommended two to three charge cycles to reach peak capacity. Installation videos are widely available for guidance.

Fits inside the existing battery compartment

The 61.60 x 54.70 x 8.70mm footprint slides into the same cavity as the factory unit. No case modifications or adapter cables are required. Built-in protection guards against overcharge, over-discharge, over-voltage and short circuits. Shock-absorbing foam in the packaging protects the cell during transit.

Questions about this item

What are the exact dimensions of this 61.60 x 54.70 x 8.70mm battery pack?

The lithium-polymer pack measures 61.60mm long, 54.70mm wide and 8.70mm thick, matching the original battery footprint for Babysense BBM01, BBM03, Bonoch BBM05 and HD S2 monitors.

How do I install the 5-pin connector correctly on the first try?

Align the 5-pin plug with the monitor socket, press straight in until it clicks, then secure the battery in the compartment; the most common error is inserting the connector at an angle, which bends pins and prevents charging.

After how many charge cycles does the 4000mAh capacity stabilise?

The manufacturer states the new cell reaches its best performance after 2 or 3 complete charge-discharge cycles, so run it from full to empty and back two or three times before relying on full runtime.
