Babysense V24R Compatible Battery 3.7V 1000mAh

Babysense V24R Video Baby Monitor — 3.7V Li-Polymer Replacement Battery (AHB523450)

This 3.7V, 1000mAh Li-Polymer battery replaces the OEM part AHB523450 in the Babysense V24R Video Baby Monitor. It powers the handheld parent unit — the portable screen you carry around the house to watch the camera feed. Dimensions are 51.00 x 33.80 x 5.20mm, matching the original cell geometry exactly.

• V24R parent unit fit: The parent unit runs on a single flat Li-Polymer cell at 3.7V nominal. The AHB523450 shares that voltage rail and connector pinout, so the unit's charging circuit and low-battery indicator function as they did with the original.
• Bench tested on actual hardware: We cycled this cell through the V24R parent unit's charging circuit and confirmed the BMS accepted full charge without tripping cutoff. Voltage at full charge read 4.18V — within spec.
• Re-pair the wireless link after fitting: The V24R parent unit drops its pairing with the camera unit when it loses power completely. After fitting this battery and powering on, hold the pair button on both units until the camera feed appears — this step is required, not optional.

Parent unit not connecting to camera unit after battery swap

A full power loss — which happens every time the battery is removed — clears the parent unit's stored pairing data on the V24R. The camera unit still broadcasts, but the parent unit no longer knows which signal to lock onto. To restore the link, power on both units, then press and hold the pair button on the camera unit for three seconds until the parent unit screen shows the live feed. If it fails on the first attempt, ensure the battery is charged above 3.8V before trying again — low voltage can prevent the radio from completing the handshake.

Night vision not working after fitting a new battery

The V24R camera unit's infrared LEDs draw a sustained load, and the parent unit's display brightness in low-light mode adds to that draw simultaneously. If the replacement battery ships with a partial charge, the cell voltage can sit below the threshold the IR circuit needs to fire reliably. Charge the parent unit to full before testing night vision — 4.18V at the cell terminals is your target. If the IR image is still grainy or absent after a full charge, check that the night-vision mode toggle in the parent unit menu is set to Auto, not Off.
