The Platinum 2 is the handheld receiver you carry around the house while the camera stays in the nursery. When the original cell loses capacity, this direct swap restores the parent unit to working order.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePlatinum 2 parent unit fit:\u003c\/strong\u003e\n    The JS803438 cell is specific to the Platinum 2 receiver. The compact 39.70 × 33.65 × 7.40mm footprint matches the battery bay exactly. The 3.7V nominal voltage matches what the parent unit's charging circuit and display board expect.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through the Platinum 2 charging cycle and confirmed the protection circuit trips correctly on overcharge and over-discharge. The BMS held stable voltage across screen-on, wireless receive, and IR illumination loads simultaneously.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eRe-pair after fitting:\u003c\/strong\u003e\n    After replacing the battery, the parent unit loses its wireless link to the camera unit when it fully powers down. Once charged and powered on, run the pairing sequence from the Platinum 2 setup menu — the camera unit will not appear on screen until the link is re-established.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Platinum 2 parent unit drains overnight with the screen on\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eRunning the Platinum 2 through the night with the screen active is a sustained high draw — the display, wireless receiver, and IR detection all pull current simultaneously. A degraded original cell cannot sustain this load, and the unit shuts off before morning. A fresh 1000mAh cell handles the combined draw, but enabling the screen timeout in the display settings extends charge life significantly. Check the Platinum 2 menu for the auto-screen-off option and set it to the shortest interval you can tolerate.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eNight vision not working after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Platinum 2 camera unit uses infrared LEDs that require stable voltage from the camera's own supply — but the parent unit's receiver IR detection circuit also has a minimum voltage threshold. If night vision appears absent immediately after fitting a new parent unit battery, the cell likely needs a full charge before the IR display circuit operates correctly. Plug the parent unit in and charge to 100% before testing night mode. If the camera-side IR LEDs are the issue, that is a camera unit power problem, not the parent unit battery.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43315069943898,"sku":"BWCS-LNP200MB-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43315069976666,"sku":"BWCS-LNP200MB-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43315070009434,"sku":"BWCS-LNP200MB-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LNP200MB-1.webp?v=1777949695","url":"https:\/\/batteryweb.com\/products\/luvion-platinum-2-replacement-battery-37v-1000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
