It fits a wide range of Sony camcorders and Video Walkman units, including the TRV56E, DCR-TRV120E, and GV-D300. The NP-F960 slot is shared across Sony's InfoLithium L-series platform, so this cell also covers the NP-F930, NP-F950, NP-F970, and several variant part numbers.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eInfoLithium L-series platform:\u003c\/strong\u003e\n    Sony's NP-F9xx and NP-F93x\/95x\/97x cells all share the same physical footprint, pin arrangement, and InfoLithium communication protocol. That shared standard is why this single cell covers over 230 Sony camcorder and video recorder models — the voltage rail and BMS handshake are consistent across the whole L-series lineup.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through a full charge-discharge cycle on a Sony InfoLithium-compatible charger. The BMS accepted the cell without fault flags, balanced correctly across the charge curve, and held voltage above the 6.0V cutoff through a complete discharge sweep.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eInfoLithium display calibration on first use:\u003c\/strong\u003e\n    Sony's InfoLithium system tracks remaining capacity by monitoring current flow in and out of the cell. On a new replacement, perform one complete charge cycle through a Sony OEM charger or the camera body before heavy use — this lets the BMS map the cell's actual discharge curve and report remaining battery accurately on-screen.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the TRV56E battery indicator reads full then drops suddenly mid-recording\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eSony's InfoLithium gauge works by integrating current, not just measuring terminal voltage. A new replacement cell has a discharge curve the BMS hasn't yet mapped, so the indicator can read full for longer than expected, then step down sharply once the cell passes a voltage threshold the firmware wasn't anticipating. This is a calibration issue, not a cell defect. Running one full charge and discharge cycle inside the camera body or on a Sony OEM charger gives the BMS enough data to recalibrate the curve. After that cycle, the remaining-battery display tracks the actual state of charge accurately through the full discharge range.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSony camcorder shows no battery or stops accepting the replacement cell after a partial charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSome Sony InfoLithium bodies perform a brief authentication check on insertion and reject cells that present below a minimum voltage threshold — typically around 5.8V to 6.0V. If the replacement cell has sat in storage and self-discharged below that window, the camera will refuse to operate or show no battery even though the cell isn't empty. Place the cell in a Sony-compatible external charger rather than the camera body to recover it; external chargers apply a trickle pre-charge that brings the cell back above the acceptance threshold. Once the cell reaches approximately 6.2V under the charger, the camera body will recognise and accept it normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333596414042,"sku":"BWCS-NF960MU-1","price":105.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333596446810,"sku":"BWCS-NF960MU-2","price":121.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333596479578,"sku":"BWCS-NF960MU-3","price":131.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NF960MU-1.webp?v=1778212994","url":"https:\/\/batteryweb.com\/products\/sony-trv56e-replacement-battery-74v-7800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
