It fits the Lumix DMC-GF2 mirrorless camera body, including the GF2CK, GF2CS, and GF2CR variants. Voltage and cell chemistry match OEM spec, so the camera body accepts the cell without modification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGF2 series fit:\u003c\/strong\u003e\n    All GF2 variants share the same battery bay dimensions, contact pin layout, and 7.4V BMS handshake. The DMW-BLD10PP and DMW-BLD10E part numbers are regional variants of the same cell — same connector, same authentication logic, all covered by this replacement.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell in a GF2 body through charge and discharge under mixed photo and 1080p video load. The BMS communicated correctly, and the camera displayed battery status without error flags across all test cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge cycle on a new GF2 cell:\u003c\/strong\u003e\n    Run one complete charge from inside the camera body or OEM charger before your first shoot. Some GF2 bodies require an internal charge cycle to calibrate the battery-remaining indicator against the new cell's discharge curve — skipping this can cause the percentage readout to behave erratically until the 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 GF2 battery percentage drops suddenly rather than gradually\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe GF2 maps its battery indicator to a voltage-threshold table tuned for the original cell's discharge curve. A replacement cell with slightly different mid-range voltage characteristics can cause the indicator to hold at a high percentage, then step down sharply as voltage drops through the threshold points. This is a calibration mismatch, not a fault. One full charge-discharge cycle in the camera body allows the BMS to re-map the indicator against the actual cell behaviour. After that cycle, the percentage steps should track normally.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eGF2 shot count lower than expected with continuous AF and stabilisation active\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe rated shot count for the GF2 is measured under CIPA standard conditions — fixed focus, no image stabilisation, minimal LCD use. In real shooting, continuous autofocus, in-body stabilisation, live histogram, and frequent EVF use all draw current simultaneously. At 850mAh and 7.4V, that combined draw depletes the cell faster than the spec figure suggests. Reduce EVF brightness and switch stabilisation off on a tripod to recover capacity. If the body still cuts out early, check that cell voltage at end of charge reaches 8.2–8.4V using a charger with a voltage readout.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333807079514,"sku":"BWCS-BLD10MC-1","price":26.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43333807112282,"sku":"BWCS-BLD10MC-2","price":29.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43333807145050,"sku":"BWCS-BLD10MC-3","price":32.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BLD10MC-1.webp?v=1778213125","url":"https:\/\/batteryweb.com\/products\/panasonic-lumix-dmc-gf2-replacement-battery-74v-850mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
