It fits the SEW-3043W, SEW-3043WP, and SEW-3043WN handsets — the portable monitor screen caregivers carry around the home. Voltage and capacity match the original spec so the parent unit powers on and connects to the camera unit without modification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSEW-3043 parent unit fit:\u003c\/strong\u003e\n    All SEW-3043 variants share the same parent handset housing, 3.8V power rail, and 455271PHV battery footprint. The flat Li-Polymer cell slots into the same bay with the same connector orientation across the range.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through the SEW-3043W parent unit's charge cycle. The BMS accepted the charge without fault flags, balanced both rails correctly, and the unit held a stable 3.8V output under display-on load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eRe-pair the wireless link after installation:\u003c\/strong\u003e\n    When the parent unit loses power completely — as it does during a battery swap — the SEW-3043 series drops its stored pairing with the camera unit. Charge the parent unit first, then hold the pairing button on both units until the link re-establishes before assuming the battery is faulty.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the SEW-3043W parent unit drains overnight with the screen on\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe parent unit's colour LCD and continuous RF link to the camera unit together draw sustained current all night. A degraded original battery accelerates this — its usable capacity has dropped well below the rated figure. This replacement restores the full 2400mAh baseline, but overnight screen-on use is still a high draw for a cell this size. Enable the parent unit's screen timeout in the display settings so the LCD dims between alerts — the RF link stays active, only the backlight cuts.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eNight vision feed dropping out after fitting a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe camera unit's IR LEDs need a stable voltage from the camera's own power source, but if the parent unit is below roughly 3.5V after installation, the handset's display driver under-performs and the night vision stream appears dark or drops entirely. This is a low-charge symptom, not a faulty battery. Charge the parent unit to full before testing night vision — once the cell reaches its nominal 3.8V, the IR feed renders correctly on the display.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43315062571098,"sku":"BWCS-SEW304MB-1","price":38.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43315062603866,"sku":"BWCS-SEW304MB-2","price":45.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43315062636634,"sku":"BWCS-SEW304MB-3","price":49.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SEW304MB-1.webp?v=1777949572","url":"https:\/\/batteryweb.com\/products\/samsung-brightview-replacement-battery-38v-2400mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
