JSLBtech Video Baby Monitor Compatible Battery 3.7V 2000mAh

JSLBtech Video Baby Monitor — 3.7V Li-Polymer Replacement Battery (AHB653860)

This 3.7V, 2000mAh lithium-polymer battery replaces the AHB653860 cell in JSLBtech Video Baby Monitor parent units. It restores power to the parent unit when the original cell has degraded or failed. Dimensions are 63.10 × 39.70 × 6.60mm — measure your existing cell before fitting.

• JSLBtech Video Baby Monitor parent unit fit: The parent unit runs a 3.7V single-cell Li-Polymer pack with a compact flat profile to fit the slim housing. This cell matches that voltage rail and physical footprint, so the BMS can read charge state correctly after installation.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on the bench. The protection circuit engaged at both low-voltage cutoff and overcharge threshold, and capacity read within expected range at 2000mAh.
• Post-swap wireless re-pair: Baby monitor parent units lose their stored camera pairing when the battery drops to zero. After fitting this battery, hold the pair button on both the parent unit and camera module until the link indicator confirms connection — skipping this step leaves the screen active but showing no feed.

Parent unit not connecting to camera unit after battery swap

When a Li-Polymer cell in a baby monitor parent unit fully discharges, the unit loses all stored settings — including the wireless pairing data for the camera. Swapping the battery does not automatically restore that link. The camera and parent unit need to re-establish their encrypted channel from scratch. Hold the pair button on the camera module first, then hold the pair button on the parent unit until both units confirm the connection with a steady indicator light or on-screen prompt.

Night vision stops working immediately after battery replacement

The IR LEDs in the camera unit draw power from the camera's own supply, but the parent unit's display brightness and IR reception both depend on sufficient voltage at the 3.7V rail. If night vision appears dead after a battery swap, the new cell is likely still at a low resting voltage from storage. Charge the parent unit to full before testing night mode — IR illumination requires the cell to be above approximately 3.6V to sustain the display and radio simultaneously. If night vision still fails after a full charge, the fault is in the camera unit, not the battery.
