It fits the Panasonic NV-DX100 camcorder. Voltage, capacity, and connector position match the original.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eNV-DX100 compatibility:\u003c\/strong\u003e\n    The NV-DX100 uses the VW-VBD815 battery rail at 7.4V nominal. The connector layout and BMS communication protocol are specific to this platform — this cell matches both the physical footprint (70.44 × 57.99 × 38.26mm) and the voltage curve the camcorder's power management expects.\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 NV-DX100 body. The BMS accepted the cell without error, maintained stable voltage under sustained video recording load, and triggered protection cutoff correctly at cell depletion.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-install charge cycle on the NV-DX100:\u003c\/strong\u003e\n    Run the first full charge cycle through the OEM charger or inside the camera body itself before heavy recording. The NV-DX100's BMS maps its battery-remaining indicator against a calibrated discharge curve — one full charge cycle from inside the body gives the system accurate data for the percentage readout going forward.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the NV-DX100 shows a dead battery indicator on a partially charged replacement cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe NV-DX100 builds its battery-level map during the first charge cycle it observes on a new cell. If the cell is installed mid-charge or discharged below 3.0V per cell before first use, the camcorder's indicator can lock onto a skewed reference point. This causes the display to read empty even when the cell holds significant charge. A full charge from flat — carried out in-body or in the OEM charger — resets this reference. After that cycle, the indicator tracks accurately against the 7.4V discharge curve.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically during recording on the NV-DX100\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eErratic percentage jumps during active recording usually mean the camcorder's fuel gauge is mapping new-cell voltage thresholds against calibration data stored from the previous (degraded) battery. A new 6000mAh cell holds voltage higher and longer through the mid-range than a worn cell, so the indicator overshoots and corrects. This is a calibration issue, not a cell fault. Discharge the battery fully in the camera, then perform a complete uninterrupted charge to 8.4V — the BMS will re-anchor its threshold map to the new cell's actual discharge curve.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333897027674,"sku":"BWCS-SVBD815-1","price":57.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333897060442,"sku":"BWCS-SVBD815-2","price":67.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333897093210,"sku":"BWCS-SVBD815-3","price":74.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SVBD815-1.webp?v=1778213590","url":"https:\/\/batteryweb.com\/products\/panasonic-nv-dx100-replacement-battery-74v-6000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
