It fits the M11, M11 Glossy, M11M, and M11P rangefinder cameras. The cell powers the imaging sensor, metering system, and electronic controls throughout a shoot.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eM11 platform compatibility:\u003c\/strong\u003e\n    All four M11 variants share the same battery compartment dimensions and voltage rail. The BP-SCL7 footprint and contact layout are identical across M11, M11 Glossy, M11M, and M11P — one cell covers the full line without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell on an M11 body and monitored BMS handshake at insertion, charge acceptance via the camera body, and discharge behaviour under continuous shooting load. The BMS registered full capacity and did not trip at any point during the test cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use charge cycle on the M11:\u003c\/strong\u003e\n    Insert the new cell and charge it fully through the camera body before your first shoot. The M11's BMS maps battery-remaining percentage against a charge curve it reads during that initial in-body cycle — skipping it can cause the indicator to read low or jump erratically until the first full cycle completes.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the M11 battery indicator reads inaccurate on a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe M11 uses a voltage-threshold system to estimate remaining charge. A new cell has a discharge curve that doesn't match the depleted original the camera learned from. Until the BMS completes one full charge-discharge cycle with the new cell inside the camera body, the percentage display can lag or jump. This is firmware behaviour, not a cell fault. One full in-body charge cycle recalibrates the display.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eM11 showing dead battery symbol on a replacement that isn't discharged\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSome M11 bodies flag a new BP-SCL7 replacement as depleted on first insertion — the camera sees an uncycled cell's resting voltage as below its internal threshold. Power the camera off, remove the cell for 30 seconds, reinsert, and power on again. If the symbol persists, place the cell on charge via the camera body until the charge indicator clears, then recheck. The body accepts the cell after the first completed charge cycle.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333549555802,"sku":"BWCS-BDM110MC-1","price":50.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333549588570,"sku":"BWCS-BDM110MC-2","price":59.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333549621338,"sku":"BWCS-BDM110MC-3","price":66.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BDM110MC-1.webp?v=1778212934","url":"https:\/\/batteryweb.com\/products\/leica-m11-replacement-battery-74v-1800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
