It fits the Panasonic Lumix DMC-F7-B, DMC-F7-N, DMC-F7PP, and related F7 compact cameras. Cross-references include CGA-S101A, CGA-S101E, CGR-S101A, and DMW-BC7.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eF7 series compatibility:\u003c\/strong\u003e\n    All Lumix DMC-F7 variants share the same 3.7V single-cell architecture, identical connector pinout, and the same BMS communication protocol — so one cell fits across the entire F7 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 through charge and discharge on an F7-B body. The BMS accepted the cell without error flags, voltage hold under flash load stayed within the camera's operating threshold, and capacity readout stabilised after one full charge cycle completed inside the camera body.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use charge cycle on F7 bodies:\u003c\/strong\u003e\n    Run one complete charge cycle from within the camera body or OEM charger before heavy shooting. The F7's battery-remaining indicator maps voltage thresholds to a known discharge curve — a new cell needs one full cycle before the display reads accurately.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFlash output dropping mid-shoot on a new CGA-S101 cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe F7's built-in flash pulls a sharp capacitor recharge current after each shot. A cell under partial charge may sag below the camera's minimum voltage threshold during that recharge draw, causing the flash to fire at reduced output or skip entirely. This isn't a defective cell — it's a voltage sag event. Keep the cell above 3.5V during extended flash shooting to avoid it.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically on the F7 display\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe DMC-F7 maps its battery indicator to a discharge voltage curve calibrated during the first full charge cycle. A replacement cell that hasn't completed that cycle presents a slightly different open-circuit voltage profile, so the camera misreads the state of charge and the percentage jumps. Charge the cell fully in the camera body once, then discharge it through normal use. After one complete cycle, the indicator stabilises and tracks accurately.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333886935130,"sku":"BWCS-PDS001-1","price":22.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43333886967898,"sku":"BWCS-PDS001-2","price":25.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43333887000666,"sku":"BWCS-PDS001-3","price":27.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PDS001-1.webp?v=1778213591","url":"https:\/\/batteryweb.com\/products\/panasonic-lumix-dmc-f7-b-replacement-battery-37v-700mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
