Sanitas SBY 98 Replacement Battery 3.7V 900mAh

Sanitas SBY 98 — 3.7V Li-Polymer Replacement Battery (1ICP6/30/48)

This 3.7V, 900mAh Li-Polymer battery fits the Sanitas SBY 98 baby monitor parent unit. It replaces the original 1ICP6/30/48 cell when capacity fades or the unit stops holding charge. Dimensions are 50.10 x 30.00 x 6.00mm — confirm against your existing cell before fitting.

• SBY 98 parent unit fit: The parent unit runs on a single flat Li-Polymer cell at 3.7V nominal. The connector, cell footprint, and BMS communication protocol are matched to the SBY 98 circuit board — no modification needed to seat the battery.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on the SBY 98 parent unit. The BMS accepted the cell, regulated charge termination correctly at 4.2V, and held voltage under sustained audio transmission load without cutoff.
• Post-swap re-pairing: After fitting a new battery, the SBY 98 parent unit loses its wireless link to the base station — complete power loss clears the pairing state. Press and hold the pairing button on the base station, then follow the link sequence on the parent unit before use.

Parent unit not connecting to the camera unit after battery swap

When the parent unit runs flat and is then replaced, the radio module loses its stored link address. The SBY 98 does not retain pairing data across a full power cycle — this is a firmware behaviour, not a fault with the new battery. To restore the link, power on both units, initiate pairing from the base station first, then select scan or pair on the parent unit. Once linked, the connection holds through normal power-off cycles as long as the battery does not fully discharge again.

Parent unit battery draining overnight with screen active

The SBY 98 parent unit screen draws significant current during night-time operation, especially with backlight on and audio monitoring active. A 900mAh cell under sustained screen-on load will deplete faster than users expect compared to a fresh OEM cell. Enable the screen timeout function in the parent unit menu — the audio channel stays live while the display sleeps. Check the unit is sitting below 3.5V at wake-up; if so, the screen timeout is not activating correctly and the setting needs to be saved again after the battery swap.
