GHB UU24 Baby Monitor Replacement Battery 3.7V 1000mAh

GHB UU24 / UU24RX — 3.7V Li-Polymer Replacement Battery (Bat-UU24)

This is a 3.7V, 1000mAh Li-Polymer battery replacing the original Bat-UU24 in GHB baby monitors. It fits the UU24 and UU24RX parent units — the handheld receiver you carry around the house while the camera unit stays in the nursery. Capacity matches the original at 1000mAh (3.7Wh).

• UU24 and UU24RX compatibility: Both models run on the same 3.7V single-cell Li-Polymer platform and share an identical connector footprint and BMS handshake. One battery fits both.
• Bench tested on actual hardware: We cycled this cell through the UU24 parent unit's charge controller. The BMS accepted the cell without fault flags, balanced correctly at 4.2V, and the low-battery LED cleared within the first charge cycle.
• Wireless re-pairing after swap: Baby monitors store their camera link in volatile memory on the parent unit. A full power-down during battery replacement clears that link. After fitting the new battery, hold the pair button on both units until the camera feed reappears on the parent screen.

Parent unit battery draining overnight during nursery monitoring

The UU24 parent unit runs its screen, radio receiver, and speaker simultaneously during overnight monitoring — that is a sustained draw on a 1000mAh cell. If the screen stays on all night at full brightness, the battery will not last until morning. Use the screen timeout setting in the menu to switch the display off while audio monitoring stays active. The radio link remains live with the screen off, so you will still hear alerts. This single change cuts overnight draw significantly.

The camera unit's IR LEDs are powered independently by the camera's own supply — but the parent unit needs adequate voltage to drive its radio receiver at full sensitivity. If the replacement battery is not fully charged before first use, the parent unit's receiver runs below its rated voltage threshold and drops the IR video stream first, since that channel requires the most bandwidth. Charge the parent unit to 4.2V (solid green charge indicator) before switching on. A partially charged cell at 3.6V or below will not maintain a stable video link from the camera's night vision mode.
