The cell matches the original pack's physical footprint at 69.60 × 50.65 × 15.15mm and uses the same connector orientation and pin count. Capacity is rated at 12.58Wh — identical to the original JVC specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGR-DVP3 and GR-DX series compatibility:\u003c\/strong\u003e\n    These camcorders share a common 7.4V dual-cell Li-ion architecture with the same BMS handshake protocol. JVC standardised the BN-V107 and BN-V114 form factor across this generation, so one cell fits the full range without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge and discharge cycles on a GR-DX300K body. The BMS accepted the cell without an incompatibility flag, and voltage output held steady across the discharge curve with no mid-session cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use charge cycle on MiniDV bodies:\u003c\/strong\u003e\n    Insert the battery and charge it fully inside the camera body or JVC AA-V37EK charger before your first recording session. The GR-series BMS maps remaining battery percentage against the cell's discharge curve during that first cycle — skipping it causes the indicator to read inaccurately throughout the pack's life.\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-DVP3 shows a dead battery indicator on a partially charged replacement cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe GR-DVP3 uses a voltage-threshold lookup to estimate remaining charge rather than a fuel-gauge IC. A new third-party cell has a slightly different discharge curve than the aged OEM pack the camera calibrated against. Until the BMS runs one complete charge-to-discharge cycle with the new cell, the voltage thresholds it reads map incorrectly, triggering a low-battery warning at what is actually 40–50% remaining capacity. Running one full charge cycle through the camera body or the JVC dedicated charger resets this mapping. After that cycle, the indicator tracks the actual state of charge correctly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically on the GR-DX300K LCD\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eErratic percentage readouts on this body are almost always a calibration mismatch, not a faulty cell. The GR-DX300K samples terminal voltage at fixed intervals and cross-references a stored discharge table; a fresh cell with a flatter mid-range voltage curve can cause the reading to jump several bars in either direction. The fix is a single full discharge — record until the camera powers itself off — then charge to 100% without interruption. After that cycle, terminal voltage during discharge aligns with the stored table and the display stabilises. If the display still jumps after two full cycles, check that the battery contacts on both cell and body are clean and making firm contact.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333877825626,"sku":"BWCS-JBV114-1","price":27.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43333877858394,"sku":"BWCS-JBV114-2","price":31.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43333877891162,"sku":"BWCS-JBV114-3","price":34.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-JBV114-1.webp?v=1778213541","url":"https:\/\/batteryweb.com\/products\/jvc-gr-dvp3-replacement-battery-74v-1700mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
