It fits the DCR-TRV120E, GV-D300 Video Walkman, CCD-TR3000E, CCD-TRV66, and 231 additional models sharing the same battery platform. Capacity is drawn from the product spec — 10200mAh \/ 75.48Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eNP-F series platform compatibility:\u003c\/strong\u003e\n    Sony's NP-F930 through NP-F975 cells all share the same physical housing, three-pin connector, and 7.4V nominal rail. The DCR-TRV and CCD-TR series use the same BMS handshake protocol, so a single cell spec covers the entire group without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through a full charge-discharge sequence and confirmed the BMS accepted the cell without fault codes. Voltage held above 7.0V under sustained video record load, and the protection circuit tripped correctly at low-voltage cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle initialisation on Info-Lithium bodies:\u003c\/strong\u003e\n    Sony Info-Lithium bodies map the battery-remaining display against a known discharge curve. On first install, run one full charge cycle through the OEM charger or camera body — this lets the BMS record the cell's actual capacity baseline and display accurate remaining charge instead of a flat or erratic readout.\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-TRV120E rejects a new NP-F cell on first install\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eSony's Info-Lithium system does more than measure voltage — it runs a two-way communication check between the battery and the body to authenticate cell data. A brand-new cell with no prior charge history can fail this check on first insertion, causing the body to display a blinking battery icon or shut down. This is not a faulty cell. Insert the battery, power on, then charge fully via the body or an OEM BC-series charger. After one complete charge cycle the body registers the cell and the communication check passes on every subsequent insertion.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically during recording\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe DCR-TRV120E's Info-Lithium indicator maps percentage to a specific voltage-vs-capacity discharge curve stored in firmware. A new replacement cell with a slightly different discharge curve causes the indicator to recalculate mid-session, which shows up as sudden jumps — 80% dropping to 40%, or briefly climbing back up. The fix is two full charge-discharge cycles through the camera body. After that, the firmware recalibrates its reference points against the actual cell curve and the percentage display stabilises. If it persists after two cycles, check the three-pin connector for oxidation and clean with isopropyl alcohol.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333673517146,"sku":"BWCS-F970-1","price":59.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43333673549914,"sku":"BWCS-F970-2","price":69.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43333673582682,"sku":"BWCS-F970-3","price":77.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-F970-1.webp?v=1778213015","url":"https:\/\/batteryweb.com\/products\/sony-dcr-trv120e-replacement-battery-74v-10200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
