It replaces OEM part numbers HRMR03, GP80AAAHC3BMX, and GP80AAAHC3BMXZ. When the original battery swells, stops holding charge, or cuts out during the night, this is the direct swap.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMBP481 \/ MBP483 parent unit fit:\u003c\/strong\u003e\n    These models share the same 3.6V three-cell Ni-MH pack format, connector orientation, and physical footprint — the parent unit's battery bay accepts all variants in this family without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through charge and discharge on the MBP483 parent unit. The BMS accepted charge without fault flags, and the unit maintained stable RF link to the camera module through the full voltage window.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eWireless link after power interruption:\u003c\/strong\u003e\n    When the parent unit loses power completely — as it does during a battery swap — it drops the paired link to the camera unit. After fitting the new battery, charge the parent unit first, then hold the pair button until the camera unit confirms connection. Skipping this step is the most common reason the monitor appears dead after a swap.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the MBP481 parent unit drains overnight with the screen on\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe MBP481 parent unit runs the LCD backlight, speaker circuit, and 2.4GHz radio simultaneously during night monitoring. That sustained draw against a 700mAh Ni-MH pack is significant. At 3.6V nominal, Ni-MH voltage drops noticeably as capacity depletes — the unit can shut off before the battery reads fully flat. Enabling the screen timeout in the monitor's settings reduces backlight load and extends the charge cycle through the night.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eParent unit shows low battery immediately after fitting a new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells ship in a partially discharged state — this is intentional for safe transport, not a defect. The parent unit reads resting cell voltage on startup, and a freshly unpacked pack sitting at around 3.3V will trigger a low-battery indicator before any charge is applied. Place the parent unit on charge for a full cycle before drawing conclusions. Once the pack reaches 3.6V under charge, the indicator clears and the unit operates normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43315068698714,"sku":"BWCS-MTP481MB-1","price":21.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43315068731482,"sku":"BWCS-MTP481MB-2","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43315068764250,"sku":"BWCS-MTP481MB-3","price":26.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MTP481MB-1.webp?v=1777949695","url":"https:\/\/batteryweb.com\/products\/motorola-mbp481-replacement-battery-36v-700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
