It replaces OEM part numbers VW-VBD210, CGA-DU21, and CGA-DU21A. The cell fits directly into the battery compartment and communicates with the camcorder's onboard BMS via the same pin arrangement as the original.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eNV-GS series compatibility:\u003c\/strong\u003e\n    These camcorders share a common battery bay and BMS communication protocol across the GS line. The VW-VBD210 form factor and voltage rail are consistent across all listed models, so one cell covers the full series 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 NV-GS hardware. The BMS accepted the cell without rejection flags, and the remaining-charge display tracked consistently through the discharge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use charge cycle on MiniDV camcorders:\u003c\/strong\u003e\n    Perform the first full charge through the camcorder body itself, not a standalone charger. Some NV-GS units map the battery-remaining indicator by running an internal calibration pass during the first in-body charge — skipping this step can cause the indicator to read incorrectly for the first several 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 NV-GS series battery indicator jumps or reads full then drops suddenly\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe NV-GS camcorders use a voltage-threshold model to estimate remaining charge rather than coulomb counting. A new cell has a slightly different discharge curve than a well-aged original, so the camera's firmware maps the voltage steps incorrectly at first. This produces sudden jumps — the display may read 75% then drop to 20% within minutes. After two or three full charge-discharge cycles, the firmware adjusts its reference points and the readout stabilises.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCamcorder powers off mid-recording despite battery showing charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the BMS detects a voltage sag during peak draw — sustained recording on MiniDV hardware spikes current demand during tape transport and optical image stabilisation simultaneously. If the cell voltage momentarily dips below the BMS cutoff threshold (typically around 6.0V under load), the camcorder shuts down even though the resting voltage reads fine. Let the battery cool for five minutes, then power on and check the resting voltage — if it recovers above 7.0V, the cell is healthy and the shutdown was a transient sag, not cell failure.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333896339546,"sku":"BWCS-VBD210-1","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333896372314,"sku":"BWCS-VBD210-2","price":38.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333896405082,"sku":"BWCS-VBD210-3","price":42.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-VBD210-1.webp?v=1778213591","url":"https:\/\/batteryweb.com\/products\/panasonic-nv-gs100k-replacement-battery-74v-2160mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
