It fits the GF2, GF2CK, GF2CS, GF2CR, and over 58 additional Lumix variants that share the same battery bay and connector. Physical dimensions are 51.83 × 36.27 × 13.83mm — identical to the original cell.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGF2 series compatibility:\u003c\/strong\u003e\n    Every model in the DMC-GF2 line uses the same 7.4V battery rail, BLD10-format connector, and BMS handshake protocol. One replacement covers the entire camera variant range without any modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the GF2 body and OEM charger. The BMS accepted charge from both, reported accurate state-of-charge after one full cycle, and held voltage above the camera's low-battery cutoff through sustained burst shooting.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use charge cycle for GF2 BMS calibration:\u003c\/strong\u003e\n    Charge this cell fully inside the camera body or OEM charger before your first shoot. The GF2's BMS maps remaining battery percentage against the discharge curve of a fresh cell — skipping this step causes erratic percentage readings from the first frame.\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 on the GF2 display after fitting a new cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe GF2 body maps its battery indicator against fixed voltage thresholds calibrated to a known discharge curve. A new replacement cell can have a slightly different internal resistance profile, so the camera misreads mid-discharge voltage and shows erratic percentage jumps. This is a calibration issue, not a faulty battery. Run one complete charge-and-discharge cycle through the camera body — the BMS relearns the curve and percentage display stabilises from the second cycle onward.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eGF2 showing dead-battery icon on a replacement cell that has charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSome GF2 bodies trip a low-voltage lockout if they detect cell voltage below 6.0V on first contact — common when a new battery has been sitting in storage at partial charge. The camera refuses to power on and shows a depleted-battery animation. Pull the battery, place it in the OEM charger until the indicator shows a full charge, then reinsert. The body accepts the cell once it reads above the 7.0V threshold on power-up.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333751373914,"sku":"BWCS-BLD10MX-1","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333751406682,"sku":"BWCS-BLD10MX-2","price":35.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333751439450,"sku":"BWCS-BLD10MX-3","price":38.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BLD10MX_1.webp?v=1778213068","url":"https:\/\/batteryweb.com\/products\/panasonic-lumix-dmc-gf2-replacement-battery-74v-1050mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
