Samsung BrightVIEW Parent Unit 3.8V 2400mAh Li-Polymer Compatible Battery

Samsung BrightVIEW / SEW-3043W Series — 3.8V Li-Polymer Replacement Battery (455271PHV)

This 3.8V, 2400mAh Li-Polymer battery replaces the OEM 455271PHV cell in the Samsung BrightVIEW parent unit. 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.

• SEW-3043 parent unit fit: 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.
• Bench tested on actual hardware: 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.
• Re-pair the wireless link after installation: 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.

Why the SEW-3043W parent unit drains overnight with the screen on

The 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.

Night vision feed dropping out after fitting a new battery

The 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.
