It powers the sensor, autofocus system, and electronic viewfinder at the same voltage and capacity as the original cell. A direct fit for the 1 V2 body with no modification required.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e1 V2 compatibility:\u003c\/strong\u003e\n    The EN-EL21 is exclusive to the NiKon 1 V2 — no other NiKon body uses this form factor or connector pinout. The cell voltage and BMS communication protocol match what the 1 V2 expects on first insertion.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on the 1 V2 body. The BMS accepted the cell, battery-remaining display updated correctly, and the camera powered the EVF and continuous AF without triggering a low-voltage cutoff prematurely.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle calibration on the 1 V2:\u003c\/strong\u003e\n    Charge this battery fully inside the 1 V2 body or OEM charger before your first shoot. The 1 V2 maps its battery-percentage display against a discharge curve — one full charge cycle from within the body lets the BMS anchor that curve correctly and show accurate remaining capacity.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the 1 V2 battery indicator drops faster during continuous video than stills\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe 1 V2 draws significantly more current during video recording than single-frame stills. The sensor runs continuously, the processor handles real-time encoding, and the EVF stays active throughout — combined, these loads pull more current than the shot-count spec assumes. The EN-EL21's 1400mAh capacity is rated against a standard stills cycle, not sustained video draw. If you shoot video frequently, carry a second cell rather than relying on a single charge.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping or resetting to 100% mid-shoot on a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the 1 V2 BMS hasn't mapped the new cell's discharge curve yet. The camera uses voltage thresholds to estimate remaining capacity — a fresh cell that hasn't been calibrated can read incorrectly because its resting voltage sits outside the camera's stored reference points. Run one complete charge-to-full, shoot until the camera gives a low-battery warning, then recharge fully. After that cycle, the percentage display should track the actual charge state accurately. If it still jumps, repeat the cycle once more before assuming a fault.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333763956826,"sku":"BWCS-ENEL21MX-1","price":19.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333763989594,"sku":"BWCS-ENEL21MX-2","price":21.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333764022362,"sku":"BWCS-ENEL21MX-3","price":22.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ENEL21MX-1.webp?v=1778213068","url":"https:\/\/batteryweb.com\/products\/nikon-1-v2-replacement-battery-74v-1400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
