Both models share the same 53.00 × 35.30 × 11.00mm form factor and single-cell 3.7V power rail. Slot it into the OEM battery bay and it connects directly to the existing contacts.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMovieline SD-10 and Powerflex 350 WiFi compatibility:\u003c\/strong\u003e\n    Both camcorders draw from an identical 3.7V single-cell architecture with matching physical dimensions and contact layout. One cell fits both without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the Movieline SD-10's charge circuit and confirmed the BMS accepted the cell, completed a full charge, and passed protection-cutoff checks at both high-voltage and low-voltage thresholds.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle conditioning on camcorder BMS:\u003c\/strong\u003e\n    Run the first full charge through the camcorder body itself, not a universal third-party charger. The Movieline SD-10's onboard charge controller needs to complete one full charge cycle internally before the battery-level indicator reads accurately during recording and playback.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Movieline SD-10 shows a dead battery indicator on a new replacement cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe SD-10 maps battery remaining using a voltage-threshold table calibrated to the original cell's discharge curve. A new replacement cell at resting voltage can sit outside the expected range the firmware considers \"charged,\" triggering the low-battery icon even when the cell is at 3.9V or above. The fix is to place the cell in the camcorder and run a full charge via the OEM power adapter. After one complete charge cycle through the body, the threshold mapping resets and the indicator tracks correctly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically during recording on the SD-10\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the camcorder's voltage-based fuel gauge samples the cell mid-draw during recording. The sensor, codec processor, and LCD backlight pull simultaneously, causing a momentary voltage sag that the firmware reads as a sharp capacity drop. The indicator then recovers when the draw stabilises, producing the jumping readout. It is a display artefact, not a cell fault. If the behaviour persists after two full charge cycles through the camcorder body, check that the battery contacts are clean and seated — oxidation on the contact pins increases resistance and amplifies the voltage sag the firmware sees.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333869240410,"sku":"BWCS-NP120FU-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333869273178,"sku":"BWCS-NP120FU-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333869305946,"sku":"BWCS-NP120FU-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NP120FU-1.webp?v=1778213403","url":"https:\/\/batteryweb.com\/products\/rollei-movieline-sd-10-replacement-battery-37v-1800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
