V-Tech BP1763 Baby Monitor Replacement Battery 3.8V 2100mAh

V-Tech RM5754HD / HD Smart Wifi Video Monitor — 3.8V Li-ion Replacement Battery (BP1763)

This is a 3.8V, 2100mAh Li-ion replacement battery for the V-Tech HD Smart Wifi Video Monitor parent unit. It fits the RM5754 and RM5754HD models, along with the 5" Digital Video Baby Monitor and eight additional V-Tech variants that share the BP1763 cell format. Swap it when the original battery no longer holds a charge or powers the parent unit through a full night.

• RM5754 / RM5754HD parent unit fit: These models share the same 3.8V single-cell architecture, connector pinout, and BMS handshake. The BP1763 cell format slots into all of them without modification to the charging circuit.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the parent unit. The BMS accepted the charge handshake correctly, and the unit powered the 5" display, Wi-Fi link, and IR night vision at normal operating voltage without tripping any protection cutoff.
• First charge after installation: Plug the parent unit into the cradle and charge it to full before placing it in use. The BP1763 ships in a partial state — the parent unit's BMS calibrates its charge gauge on the first full cycle, so a short first charge will give inaccurate battery level readings on screen.

Parent unit not connecting to camera unit after battery swap

When the parent unit loses power completely during a battery swap, it drops its stored wireless pairing data. This is normal behaviour — the unit doesn't retain the camera link without continuous power. After fitting the new battery and charging, press and hold the pairing button on the camera unit until the parent unit rediscovers it. The link restores in under 60 seconds on a fully charged cell.

Battery level indicator showing full but parent unit shutting off early

This happens when the BMS charge gauge wasn't calibrated on the first cycle. The parent unit reads a surface voltage after a partial charge and reports 100%, but the cell isn't actually full. Run one complete charge from flat to full without interrupting it. After that first full cycle, the gauge tracks accurately and the unit holds charge as expected.
