It fits the VL-NZ80, VL-NZ50S, VL-NZ155, VL-NZ105, and over 27 additional Sharp MiniDV camcorder models. Same voltage, same connector, same BMS handshake as the original pack.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVL-NZ series camcorder compatibility:\u003c\/strong\u003e\n    These models share a common 7.4V two-cell Li-ion architecture with a matched connector and BMS communication line. That uniform power rail is why one pack covers the full range without any adapter or 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 a VL-NZ80 body. The BMS accepted the pack on first install, reported accurate charge state, and held voltage through sustained recording load without triggering a premature low-battery cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use charge cycle on MiniDV camcorders:\u003c\/strong\u003e\n    Run one full charge cycle through the OEM charger or inside the camcorder body before your first shoot. Sharp's BMS on this series maps the battery-remaining indicator against internal cell data — skipping this step can cause the display to read inaccurately for the first few sessions.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the VL-NZ80 drops to \"low battery\" warning early on a new pack\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eSharp's battery gauge on the VL-NZ series uses a voltage-threshold map calibrated to the original cell's discharge curve. A fresh replacement cell with a slightly different internal resistance will cause the indicator to trigger the warning at a higher state of charge than necessary. The camcorder isn't actually low — the gauge hasn't yet learned the new cell's curve. After two or three full charge-discharge cycles through the camera body, the readings settle and the warning aligns correctly with actual remaining charge.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCamcorder shows no battery or powers off immediately after inserting new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the replacement cell ships at a low storage voltage — typically below 3.0V per cell, or around 6.0V total pack voltage. The VL-NZ80's BMS interprets this as a dead or invalid battery and refuses to power the device. Place the pack in the OEM charger for a full charge cycle before inserting it into the camcorder body. Once the pack reaches at least 7.2V, the BMS re-evaluates and accepts it normally on the next power-on.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333862129754,"sku":"BWCS-BTL445-1","price":28.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43333862162522,"sku":"BWCS-BTL445-2","price":32.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43333862195290,"sku":"BWCS-BTL445-3","price":35.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BTL445-1.webp?v=1778213290","url":"https:\/\/batteryweb.com\/products\/sharp-vl-nz80-replacement-battery-74v-2000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
