It fits the NiKon Z50, Z50 ZFC, Z30, and Z FC mirrorless camera bodies. Voltage and cell format match the OEM part exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eZ50, Z30, and ZFC platform fit:\u003c\/strong\u003e\n    All four models share the EN-EL25 battery bay, the same 7.6V nominal voltage rail, and the same BMS handshake protocol. One cell format covers the full lineup.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the Z50 body and an OEM-compatible charger. The BMS accepted the cell, reported charge state correctly, and held voltage within expected thresholds across discharge.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle initialisation on the Z50:\u003c\/strong\u003e\n    Run the first full charge from inside the camera body or an OEM-spec charger — not a generic USB charger. The Z50's BMS maps the discharge curve on that first cycle to calibrate the battery-remaining display. Skipping this step causes the indicator to read inaccurately 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 on the Z50 display with a new cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Z50 uses a voltage-threshold model to estimate remaining charge. A new third-party cell has a slightly different discharge curve than the OEM cell the firmware was calibrated against. This makes the indicator jump — often dropping suddenly from 60% to 20% with no warning. The fix is one full charge-discharge cycle run entirely within the camera body. After that cycle, the BMS has enough curve data to map percentage accurately, and the jumping stops.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eZ50 showing incompatible battery or refusing to power on with a new EN-EL25 cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Z50 runs an authentication check on insert. If the cell arrives partially discharged — typically below 3.5V per cell — the BMS may reject it outright and display an incompatible or no-battery warning. Place the cell in an OEM-compatible charger and bring it to full charge before inserting it into the camera body. Once fully charged, reinsert and power on. If the body still rejects it, hold the power button for 10 seconds to force a BMS re-initialisation cycle.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333611487322,"sku":"BWCS-NKZ500MX-1","price":46.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333611520090,"sku":"BWCS-NKZ500MX-2","price":53.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333611552858,"sku":"BWCS-NKZ500MX-3","price":58.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NKZ500MX-1.webp?v=1778212995","url":"https:\/\/batteryweb.com\/products\/nikon-z50-replacement-battery-76v-1280mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
