{"title":"Baby Phone \u0026 Baby Monitor","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eWhen you put your baby down for the night, the last thing you want to think about is whether the monitor is going to stay on long enough to do its job. Baby monitors and baby phones run around the clock — through nap times, overnight stretches, and every quiet moment in between — and the battery in the parent unit or camera takes the full brunt of that continuous use day after day. Over time that constant demand wears the battery down, and what used to last through a full night starts cutting out in the early hours when you need it most. A fresh replacement is a small fix with a big impact on the peace of mind that a good baby monitor is supposed to deliver in the first place.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eWe carry replacement batteries for a wide range of video and audio baby monitors and baby phone handsets from the brands parents trust most — Motorola, VTech, Infant Optics, Nanit, Angelcare, Philips Avent, and more — covering both camera units and the portable parent handsets that travel room to room with you while your baby sleeps. Whether your monitor battery drains before morning, the parent unit won't hold a charge between uses, or the camera keeps dropping offline overnight, finding the right replacement here is quick and specific to your exact monitor model. Get the right battery in place and go back to sleeping soundly knowing your monitor is going to stay on as long as your baby does.\u003c\/p\u003e","products":[{"product_id":"heimvision-soothe-3-baby-monitor-replacement-battery-37v-3000mah-li-polymer","title":"HeimVision Soothe 3 Baby Monitor Replacement Battery 3.7V 3000mAh","description":"\u003cdiv class=\"bpw-desc\"\u003e\n  \u003ch2 class=\"bpw-desc-h2\"\u003eHeimVision Soothe 3 — 3.7V Li-Polymer Replacement Battery (BAT-HV3-A2)\u003c\/h2\u003e\n\n  \u003cp class=\"bpw-desc-lead\"\u003eThis 3.7V, 3000mAh lithium-polymer battery replaces the OEM pack in the HeimVision Soothe 3 baby monitor parent unit.

Most overnight drain complaints trace to the screen timeout being disabled. Go into the parent unit display settings and set the screen to auto-off after 30–60 seconds. The unit continues transmitting audio with the screen off, so you lose no monitoring function. This change alone significantly reduces overnight draw on the 2100mAh cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eNight vision feed not appearing after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe SC850 camera unit's IR LEDs are powered independently from the camera side, but the parent unit requires adequate voltage to render and display the IR feed correctly. If night vision appears blank or scrambled immediately after a battery swap, the new cell may not yet be at sufficient charge. Charge the parent unit to full on the base station before testing night vision — the display-side processing needs a stable voltage above 3.6V to handle the IR signal.
