It fits the CCD-TRV108, CCD-TRV118, CCD-TRV126, CCD-TRV128, and over 77 additional Sony CCD-TRV and DCR series models. Dimensions are 55.60 × 38.30 × 20.50mm — same form factor as the original.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCCD-TRV and DCR series compatibility:\u003c\/strong\u003e\n    These camcorder bodies share the same InfoLITHIUM battery rail and communication protocol. The NP-QM50D and NP-QM51D slots fit the same bay, use the same five-pin connector, and the BMS speaks the same voltage reporting language — which is why one cell covers so many Sony bodies across that generation.\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 CCD-TRV series body. The BMS handshake completed without error, the InfoLITHIUM percentage indicator tracked consistently through the discharge curve, and no overcurrent trips fired during motor-driven tape transport.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eInfoLITHIUM display calibration on first use:\u003c\/strong\u003e\n    On first install, run one complete charge cycle through the camera body or Sony OEM charger — not a third-party charger — before shooting. The InfoLITHIUM system maps remaining time against a baseline charge profile. Skipping this step causes the minutes-remaining display to read incorrectly from the first session.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSony InfoLITHIUM rejection on third-party cell first install\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSony's InfoLITHIUM protocol sends a handshake query to the battery before the camera body boots fully. If the cell sits in storage at low voltage — common with replacement stock — the BMS may not respond fast enough and the camera throws a battery error before any charging occurs. This is not a defective cell. Insert the battery, connect the AC adapter or OEM charger, and let it sit for 15 minutes before powering the camera on. Once the cell voltage rises above approximately 6.8V, the handshake completes and the body accepts it normally.\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 InfoLITHIUM display calculates remaining capacity against a voltage-threshold curve calibrated to the original cell's discharge profile. A new replacement cell — even a correctly specced one — discharges along a slightly different curve until the camera has logged one full cycle. Percentage readings can jump several points up or down mid-recording during that first cycle. Run one full charge-to-empty cycle without interruption and the indicator stabilises. After that cycle, readings should track within a few percent across a normal discharge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333921079386,"sku":"BWCS-QM51D-1","price":37.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43333921112154,"sku":"BWCS-QM51D-2","price":43.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43333921144922,"sku":"BWCS-QM51D-3","price":46.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-QM51D-1.webp?v=1778213590","url":"https:\/\/batteryweb.com\/products\/sony-ccd-trv108-replacement-battery-74v-1300mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
