Levana Astra Baby Monitor Compatible Battery 3.7V 1800mAh

Levana Astra / Ovia Series — 3.7V Li-Polymer Replacement Battery (055070)

This is a 3.7V, 1800mAh lithium-polymer battery with OEM part number 055070. It fits the parent unit of the Levana Astra, Ovia, 30018PU, and Keera baby monitors, plus three additional compatible models. When the original cell degrades and the parent unit stops holding charge through a night shift, this is the direct swap.

• Astra, Ovia, Keera, and 30018PU parent units: These models share the same 3.7V battery platform, connector pinout, and BMS handshake protocol on the parent unit board. One cell covers all four variants without modification.
• Bench tested on actual hardware: We cycled this cell on a Levana parent unit and monitored BMS charge acceptance across three full cycles. The protection circuit engaged correctly at both low-voltage cutoff and charge termination — no anomalous behaviour at any stage.
• Wireless re-pair after swap: The Astra parent unit stores its camera pairing in volatile memory backed by the main battery. A full power loss — which happens during any battery swap — clears that link. Run the pairing sequence from the monitor menu immediately after fitting the new cell.

Parent unit battery draining faster overnight with screen on

The Astra parent unit runs the LCD backlight, wireless receiver, and audio amplifier simultaneously during active monitoring. That sustained draw is significantly higher than standby. A degraded original cell may have masked this by showing a false full charge before collapsing mid-session. With a fresh 1800mAh cell, enable the screen timeout function in the monitor's display settings — this cuts the backlight after a set interval while keeping audio and wireless active, which reduces the overnight draw substantially.

IR night vision dropping out shortly after battery replacement

The camera unit's IR LEDs pull a brief current spike when night vision activates. If the parent unit battery is below roughly 3.5V when this handshake fires, the radio link can drop and night vision won't initialise. This is a voltage floor issue, not a pairing fault. Charge the parent unit to full before first use — confirmed full charge on the Astra is indicated by a solid green LED on the charging dock, not just the on-screen bar, which can read prematurely high.
