It slots directly into the battery compartment on these models and restores full recording and playback operation. Capacity is rated at 1800mAh (6.66Wh), matching the original cell specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHDV-8800 \/ HDC-8800 \/ HD-C3 \/ HD-D10II compatibility:\u003c\/strong\u003e\n    These four models share the same 3.7V single-cell architecture, battery footprint, and connector pinout, which is why one cell covers the entire group. The BMS on each body reads the same voltage thresholds from the cell.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on a compatible body. The BMS accepted the cell without error flags, voltage held stable under sustained video encode load, and the protection circuit tripped correctly at low-voltage cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-install charge cycle:\u003c\/strong\u003e\n    On first use, run one full charge cycle through the camera body or OEM charger before heavy shooting. Some VIVIKAI BMS implementations require this cycle to calibrate the battery-remaining indicator to the new cell's discharge curve.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage reading jumping or freezing on the HDV-8800 display\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe HDV-8800's battery indicator maps fixed voltage thresholds to percentage steps. A new replacement cell has a slightly different discharge curve than the aged original, so the camera body can misread the state of charge early in the cell's life. This shows as the percentage counter jumping several steps at once, or sticking at one level then dropping fast. Run two to three full charge-discharge cycles through the camera body and the indicator will track more accurately as the BMS learns the cell's actual discharge profile.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCamera body shows dead-battery indicator immediately after fitting a charged replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the BMS has not yet completed an initial handshake with the new cell. The body reads an open-circuit voltage it does not recognise and defaults to a dead-cell flag rather than attempting to draw current. Insert the battery and place the camera on charge via the OEM charger or USB port for at least five minutes, then power on. The BMS re-polls the cell once a trickle charge has raised the recognised voltage above the body's minimum acceptance threshold, typically 3.0V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333867536474,"sku":"BWCS-NP120FU-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333867569242,"sku":"BWCS-NP120FU-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333867602010,"sku":"BWCS-NP120FU-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NP120FU-1.webp?v=1778213403","url":"https:\/\/batteryweb.com\/products\/vivikai-hdv-8800-replacement-battery-37v-1800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
