It fits the DCR-DVD908E, DCR-HC47, HDR-HC7E, DCR-SR220D, and over 220 other Sony camcorder models sharing the same InfoLITHIUM H-series connector and BMS protocol. Voltage and capacity match the original Sony specification exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eH-series camcorder compatibility:\u003c\/strong\u003e\n    All models listed share Sony's InfoLITHIUM H-series battery slot, which uses a five-pin connector to pass real-time capacity data to the camcorder body. The physical housing, pin layout, and voltage rail are identical across this group, so one cell services all of them.\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 an HDR-HC7E body. The BMS handshake completed on first insertion, and the InfoLITHIUM remaining-time display populated within one charge cycle without error codes or cutoffs.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use charge cycle on NP-FH100 replacements:\u003c\/strong\u003e\n    Charge this cell fully inside the camera body or OEM charger before your first shoot. Sony's InfoLITHIUM system calibrates its remaining-time estimate against the cell's discharge curve during that first supervised cycle — skipping it causes the indicator to read inaccurately for 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 DCR-DVD908E shows a dead battery indicator on a partially charged replacement\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe DCR-DVD908E uses Sony's InfoLITHIUM protocol to display remaining charge as a time estimate, not just a bar. This requires the camera to map its discharge threshold table against the actual cell's voltage curve. A fresh replacement cell starts with no calibration data on record, so the camera defaults to a conservative read and may flash a low-battery warning even when the cell is at 6.8V or above. One full charge-to-discharge cycle inside the camera body lets the BMS log the curve and align the display correctly. After that cycle, the indicator tracks accurately through the full charge range.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically on the DCR-DVD908E display\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the remaining-time figure skips — say, from 45 minutes to 12 minutes without warning — the InfoLITHIUM system has lost its reference point for where the cell sits on its discharge curve. This typically happens when the battery was swapped mid-session or the cell sat discharged for an extended period, dropping below the BMS re-read threshold of around 3.0V per cell (6.0V total pack). Charge the pack to full in the camera body without interruption, then let the camera run it down in one session. That rebuilds the discharge map and stabilises the readout.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333915476058,"sku":"BWCS-FH100-1","price":35.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43333915508826,"sku":"BWCS-FH100-2","price":41.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43333915541594,"sku":"BWCS-FH100-3","price":45.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-FH100-big.webp?v=1778213575","url":"https:\/\/batteryweb.com\/products\/sony-dcr-dvd908e-replacement-battery-74v-2200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
