It slots into the same battery compartment as the original BP-DC15 and powers the camera's sensor, image processor, and LCD display. Use it as a direct swap when your original cell no longer holds a usable charge.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eD-Lux Type 109 fit:\u003c\/strong\u003e\n    The Type 109 shares its battery platform with the Panasonic LX100 — same 7.4V rail, same physical footprint, same BMS handshake protocol. This cell meets those electrical requirements for the Leica-branded body.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through full charge and discharge cycles on a Type 109 body. The BMS accepted the cell without error flags, voltage delivery held steady across shooting, playback, and LCD-on idle states.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use charge cycle on the Type 109:\u003c\/strong\u003e\n    Before heavy shooting, run one complete charge cycle through the camera body or OEM charger. The Type 109's BMS uses that first cycle to calibrate the battery-remaining indicator to the new cell's discharge curve — skipping it leads to inaccurate percentage readings from the start.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping around on the D-Lux Type 109 display\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Type 109 maps its battery indicator to a voltage-threshold table tuned to the original BP-DC15's discharge curve. A new third-party cell may have a slightly different curve — the camera's indicator then misreads where it sits in the discharge cycle. You'll see the percentage jump from 80% to 50% or stall at a fixed value until voltage drops into a range the camera recognises. Running two or three full charge-discharge cycles through the body corrects the mapping. After those cycles the indicator tracks the new cell accurately.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCamera shows dead battery icon on a replacement cell that just came off the charger\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSome D-Lux Type 109 bodies reject a new cell on first install with a low or no battery warning — even at full charge. This is a BMS authentication check, not a faulty battery. The fix is straightforward: insert the cell, let the camera attempt to power on, then place it in the charger for a short top-up charge via the camera body's charging circuit. That handshake resets the BMS flag. After one charge cycle this way the camera powers on normally and the warning clears.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333653135450,"sku":"BWCS-BLG10MX-1","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333653168218,"sku":"BWCS-BLG10MX-2","price":35.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333653200986,"sku":"BWCS-BLG10MX-3","price":39.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BLG10MX-1.webp?v=1778213016","url":"https:\/\/batteryweb.com\/products\/leica-d-lux-type-109-replacement-battery-74v-980mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
