It also cross-references CGA-DU14 and CGA-DU14A part numbers used across Panasonic's compact camcorder range from the mid-2000s. Physical dimensions are 41.44 × 36.09 × 32.84mm — confirm your battery compartment matches before ordering.\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 models share the same 7.4V battery rail, connector pinout, and BMS communication protocol. A single cell swap covers the full NV-GS10 through NV-GS150 range without wiring or firmware differences.\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 series hardware. The BMS handshake completed without rejection, and the protection circuit responded correctly to both over-discharge and over-current conditions during recording load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge cycle on NV-GS camcorders:\u003c\/strong\u003e\n    Charge the battery fully inside the Panasonic OEM charger or directly in the NV-GS camera body before your first shoot. Some Panasonic camcorder BMS units require this initial in-body charge cycle to calibrate the battery-remaining display correctly.\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-GS10 shows a dead battery indicator on a partially charged replacement cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe NV-GS10 maps its battery indicator to specific voltage thresholds it learned from the original OEM cell's discharge curve. A new replacement cell with a slightly different internal resistance will hit those thresholds at different state-of-charge points. The camera can report empty when the cell is still at 6.8V or above. After one full charge-to-discharge cycle through the camera body, the BMS recalibrates and the indicator tracks accurately.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically on the NV-GS display mid-recording\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the camcorder's voltage-threshold indicator interprets the new cell's discharge curve differently from the original. During active recording, combined draw from the CCD sensor, LCD panel, and tape mechanism causes voltage to dip briefly, triggering a sudden percentage drop. The display then recovers when the load eases. Run the cell through one complete charge and discharge inside the camera body — by the second cycle the percentage reading stabilises and the display reflects actual remaining capacity.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333896929370,"sku":"BWCS-VBD140-1","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333896962138,"sku":"BWCS-VBD140-2","price":35.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333896994906,"sku":"BWCS-VBD140-3","price":38.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-VBD140-1.webp?v=1778213591","url":"https:\/\/batteryweb.com\/products\/panasonic-nv-gs10-replacement-battery-74v-1440mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
