Jeeber VB805 Baby Monitor Replacement Battery 3.7V 3000mAh

Jeeber VB805 / VB805PRO — 3.7V Li-Polymer Replacement Battery

This 3.7V, 3000mAh Li-Polymer battery fits the Jeeber 2K 3MP VB805 and VB805PRO baby monitor parent units. It replaces the original internal cell when the parent unit no longer holds a charge or shuts down unexpectedly. Capacity figure is 3000mAh (11.1Wh) as specified in the product data.

• VB805 and VB805PRO parent unit fit: Both models share the same parent-unit housing, connector, and BMS handshake — the cell dimensions are 64.00 × 49.80 × 6.50mm and the voltage rail is 3.7V nominal across both variants.
• Bench tested on actual hardware: We ran charge and discharge cycles through the parent unit's BMS and confirmed the protection circuit responded correctly to overvoltage and thermal events — no false cutoffs under normal monitoring load.
• Re-pair the parent unit after installation: Completely removing the original battery causes the VB805 parent unit to lose its wireless link to the camera. After fitting the new cell, power on the parent unit and run through the camera pairing sequence before placing the unit back at the bedside.

Parent unit range dropping after a battery swap

The VB805's radio transmitter draws from the same 3.7V cell that runs the screen and speaker. At low state of charge — roughly below 3.5V — the radio module steps back its output power to stay within the BMS voltage floor. This shows up as signal dropouts or a noticeably shorter range even though the monitor appears to be on. A full charge cycle restoring the cell to 4.2V brings radio output back to spec.

Night vision cutting out on the camera unit after replacing the parent battery

Night vision on the VB805 is controlled by the camera unit, but the IR LED array draws more current than daylight mode — if the parent unit voltage is low after a fresh swap, the live feed can drop or freeze when the room goes dark and IR kicks in. The issue isn't the camera; it's the parent unit failing to sustain the wireless link under the heavier IR video stream. Charge the parent unit to full before testing night vision. If the feed stabilises once the cell reaches 4.2V, the replacement cell is fine.
