This replacement cell runs at 7.4V with 1020mAh (7.55Wh) capacity — matching the original cell's output for the sensor, autofocus, and LCD systems. It fits the 1 V2 body directly with no adapter or modification needed.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eNiKon 1 V2 compatibility:\u003c\/strong\u003e\n    The 1 V2 uses the EN-EL21 form factor exclusively — the voltage rail and connector pinout are specific to this model. No other NiKon 1-series body shares this cell, so there is no cross-fit risk with other cameras in the 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 1 V2 body and the MH-27 charger. The BMS completed handshake on first insertion and battery-remaining indicators tracked consistently across full discharge. No false-low readings appeared during testing.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle charge in-body:\u003c\/strong\u003e\n    Seat the new cell in the 1 V2 body and run one full charge via the camera before heavy shooting. The 1 V2 BMS maps its percentage display to the cell's discharge curve during that initial in-body charge — skipping it can cause the indicator to read erratically from the first session.\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 1 V2 display after fitting a new cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe 1 V2 tracks charge level by mapping voltage thresholds to percentage steps. A new cell's discharge curve does not always align immediately with the camera's stored reference — especially on the first partial cycle. This causes the indicator to skip steps or drop suddenly between shots. Running one full charge-to-discharge cycle inside the camera body recalibrates the threshold mapping. After that cycle, the display stabilises and tracks the actual cell state accurately.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eShot count lower than expected during continuous AF or burst shooting\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe 1020mAh rating reflects steady-state draw, not peak-load conditions. Continuous autofocus, burst mode, and LCD-on shooting each pull additional current beyond the baseline spec. The 1 V2's phase-detect AF system draws particularly hard during tracking sequences, compressing the available shot count noticeably versus single-shot use. Switching the EVF off when shooting in bright conditions and limiting continuous AF to active tracking sequences reduces per-shot draw and extends the charge between swaps.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333763825754,"sku":"BWCS-ENEL21MC-1","price":18.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333763858522,"sku":"BWCS-ENEL21MC-2","price":19.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333763891290,"sku":"BWCS-ENEL21MC-3","price":20.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ENEL21MC_1.webp?v=1778213068","url":"https:\/\/batteryweb.com\/products\/nikon-1-v2-replacement-battery-74v-1020mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
