It slots into the same battery compartment as the original cell and powers the camera body, display, autofocus, and image stabilisation systems. No OEM part number applies to this unit — fit is confirmed by voltage, form factor (70.80 × 38.50 × 21.00mm), and connector position.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVM720 and VM7200 compatibility:\u003c\/strong\u003e\n    Both models share the same battery bay dimensions and voltage rail. The BMS in each body expects a 7.4V nominal cell with this physical footprint — swapping between the two models with this battery works without modification.\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 a VM720 body. The BMS accepted the cell, percentage reporting tracked correctly after the first full charge cycle, and no cutoff events occurred during continuous video capture or burst shooting.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use charge cycle on VM720 \/ VM7200:\u003c\/strong\u003e\n    Insert this battery and charge it fully inside the camera body before your first shoot. Some NiKon camera BMS systems map their battery-remaining display to the discharge curve during the initial in-body charge — skipping this step can cause the indicator to read inaccurately for several cycles.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the VM720 shows a dead-battery icon on a partially charged replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe VM720 battery indicator reads voltage thresholds mapped from the original cell's discharge curve. A new third-party cell has a slightly different curve profile, so the camera body can misread remaining charge on early cycles. This shows up most often as a sudden \"battery empty\" icon when actual cell voltage is still above 7.0V. Charge the battery fully in-body once — the BMS recalibrates its threshold mapping against the new cell's behaviour and the indicator stabilises.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically mid-shoot\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eErratic percentage jumps — for example, 60% dropping to 20% then recovering — point to the camera's voltage-to-percentage lookup table not yet aligned to the replacement cell's discharge curve. This is separate from a dead-battery false alarm and persists for two to three charge cycles on a new cell. Run two or three full charge-to-discharge cycles in the camera body. After that, the BMS stabilises its readings and percentage display tracks the actual cell state accurately down to approximately 3.5V per cell (7.0V pack).\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333925470298,"sku":"BWCS-F550-1","price":37.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333925503066,"sku":"BWCS-F550-2","price":41.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333925535834,"sku":"BWCS-F550-3","price":45.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-F550-1.webp?v=1778213575","url":"https:\/\/batteryweb.com\/products\/nikon-vm720-replacement-battery-74v-2000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
