It fits the C-LUX1, D-LUX2, D-LUX3, and D-LUX 4 compact cameras. The cell matches OEM voltage and capacity to keep the camera's metering, autofocus, and LCD functions running correctly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eC-LUX1 and D-LUX platform fit:\u003c\/strong\u003e\n    These four models share the same BP-DC4 form factor, contact layout, and 3.7V rail. The BMS in each body expects the same charge termination voltage, so one cell covers the entire range without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on a D-LUX3 body. The BMS accepted the cell on first install, reported battery level correctly, and held charge termination at 4.2V as expected.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use charge cycle on C-LUX1 and D-LUX bodies:\u003c\/strong\u003e\n    Run one full charge inside the camera body or OEM charger before your first shoot. Some D-LUX BMS firmware maps battery-remaining percentage by learning the new cell's discharge curve during that initial cycle — skipping it can cause erratic indicator readings.\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 4 battery indicator jumps during continuous shooting\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe D-LUX 4 uses a voltage-threshold system to estimate remaining charge. During bursts or sustained LCD-on shooting, current draw spikes and momentarily drops cell voltage below a threshold, causing the indicator to step down suddenly. When the load eases, voltage recovers and the reading jumps back up. This is normal behaviour with any Li-ion cell — it does not mean the battery is faulty. After the first full charge cycle, the camera's firmware maps the new cell's discharge curve more accurately and the jumps reduce.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCamera body shows dead battery on a cell that still has charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the BMS has not yet accepted the replacement cell's resting voltage as a valid starting point. The camera reads the open-circuit voltage against its internal map and flags it as depleted if the two don't match. Place the battery in the OEM charger or the camera body and run a full charge cycle to 4.2V. After one complete charge, the body recalibrates its reference and the indicator reads correctly from that point forward.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333908463706,"sku":"BWCS-NP70FU-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333908496474,"sku":"BWCS-NP70FU-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333908529242,"sku":"BWCS-NP70FU-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NP70FU-1.webp?v=1778213591","url":"https:\/\/batteryweb.com\/products\/leica-c-lux1-replacement-battery-37v-1150mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
