It powers the imaging sensor, processor, and LCD display. Dimensions are 44.44 × 35.92 × 6.44mm — same footprint as the original cell.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eD-LUX platform fit:\u003c\/strong\u003e\n    The D-LUX uses a single-cell Li-ion pack at 3.7V with a three-contact connector that carries both power and BMS data. This battery matches that connector layout and voltage rail so the camera body can communicate charge state correctly.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through the D-LUX charge circuit and confirmed the BMS handshake completed on first insertion. The protection circuit held cutoff at the correct low-voltage threshold and the camera body reported charge level without fault flags.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle charging on the D-LUX:\u003c\/strong\u003e\n    Charge this battery fully inside the camera body or OEM charger before your first shoot. The D-LUX BMS maps its battery-remaining display against a charge curve it reads during that initial cycle — skipping it causes the indicator to read inaccurately for the first few uses.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the D-LUX shows a dead-battery indicator on a partially charged replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe D-LUX uses voltage-threshold mapping to estimate remaining charge. A new third-party cell has a slightly different discharge curve than the OEM cell the camera was calibrated against. On first insertion, the camera may misread mid-charge voltage as critically low. One full charge cycle inside the camera body resets this — the BMS recalibrates its thresholds to the new cell's actual discharge profile.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically during a shoot\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eErratic percentage readouts happen when the camera's indicator firmware maps voltage steps to charge percentages using OEM cell data. A replacement cell discharges along a slightly different curve, so the same voltage reading lands at a different percentage point. The display catches up in jumps rather than smooth steps. Run two full charge and discharge cycles through the camera body — by the second cycle the indicator stabilises against the new cell's actual curve.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333897683034,"sku":"BWCS-BCA7-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333897715802,"sku":"BWCS-BCA7-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333897748570,"sku":"BWCS-BCA7-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BCA7_1.webp?v=1778213575","url":"https:\/\/batteryweb.com\/products\/leica-d-lux-replacement-battery-37v-700mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
