It replaces OEM part numbers BN-V25, BN-V25U, BN-V65, BN-V12, BN-V15, BN-V20, BN-V22, and related variants. Physical dimensions are 89.30 × 46.50 × 37.80mm — confirm your original battery matches before fitting.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCross-model fit on the BN-V series:\u003c\/strong\u003e\n    JVC used the same 6V Ni-MH cell platform across multiple GR-series MiniDV camcorders from this era. The connector pinout and voltage rail are consistent across the BN-V11U through BN-V24U family, which is why one replacement cell covers such a wide model range.\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 JVC GR-series body. The BMS accepted the cell without error flags, and voltage output held steady across the draw curve during both recording and playback modes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle initialisation on Ni-MH bodies:\u003c\/strong\u003e\n    Ni-MH cells in JVC camcorders benefit from being charged fully in the OEM charger or camera body before first use. Some GR-series bodies need one complete in-camera charge cycle to map the new cell's discharge curve to the battery-remaining indicator accurately.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the GR-1U battery indicator reads full then drops suddenly mid-recording\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells have a relatively flat discharge curve for most of their capacity range. The GR-series voltage-threshold indicator was calibrated to the original BN-V series cell's specific discharge profile. A new or aged cell may show full bars until voltage drops past a narrow cliff point near the end of the discharge cycle, causing the indicator to jump from showing charge remaining to near-empty with little warning. This is a calibration mismatch between the indicator circuit and the cell — not a fault with the replacement. Running one full charge-discharge cycle in the camera body helps the indicator re-anchor to the new cell's actual curve.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCamera body stays off after fitting a new cell — no startup response\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the GR-1U shows no response after a new Ni-MH cell is fitted, the cell likely shipped at a low state of charge — common with Ni-MH chemistry during storage. The camera's power circuit requires the cell voltage to meet a minimum threshold before the body will initialise. Place the cell in the OEM charger for at least 30 minutes before retrying. If the body still does not start, check that the battery door is fully latched, as the GR-1U has a door-open interlock that cuts power at the connector — the cell must read at least 5.4V at the terminals before the body will respond.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43336963031130,"sku":"BWCS-PDHV40-1","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43336963063898,"sku":"BWCS-PDHV40-2","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43336963096666,"sku":"BWCS-PDHV40-3","price":43.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PDHV40-1.webp?v=1778213554","url":"https:\/\/batteryweb.com\/products\/jvc-gr-1u-replacement-battery-6v-4200mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
