It fits the DCR-IP220E, DCR-IP200K, DCR-HC1000E, DCR-IP1K, and 26 additional models that share the same battery bay and connector. Voltage and capacity match original Sony specifications exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMulti-model fit across the MiniDV line:\u003c\/strong\u003e\n    These camcorders share a common 7.4V battery rail, connector pinout, and BMS communication protocol. Any body in this range that accepts an NP-FF50 or NP-FF51 will physically seat and electrically accept this cell 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 the DCR-IP220E's onboard charger and monitored BMS handshake at first insertion. The camera accepted the cell, began charging immediately, and reported remaining charge without error across multiple discharge cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use charge cycle for display accuracy:\u003c\/strong\u003e\n    Charge this battery fully inside the camera body or OEM charger before your first shoot. Sony's BMS in this series maps its battery-remaining display against a full reference charge cycle — skipping this step can cause the indicator to show inaccurate percentages until one complete cycle is logged.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSony MiniDV BMS rejecting a new NP-FF50 replacement on first install\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eSony's compact MiniDV bodies run an authentication check when a new cell is seated. If the BMS doesn't recognise the cell's initial voltage profile, the camera may display a flashing battery icon or refuse to power on. This is not a fault with the replacement cell — it's the BMS waiting for a charge event to validate the cell. Seat the battery, connect the camera to the OEM charger, and allow a full charge to complete. After one full charge, the camera body will accept the cell normally and resume accurate reporting.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically on the DCR-IP220E display\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eSony's percentage indicator in this series is calibrated against the original NP-FF50 discharge curve. A new replacement cell — even at identical capacity — can have a slightly different mid-range voltage slope, causing the display to skip between readings as it recalculates against stored thresholds. This is a display mapping issue, not a cell fault. Run two full charge-discharge cycles and the BMS recalibrates its reference points. After that, the indicator stabilises and tracks accurately down to the 3.0V per-cell cutoff.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333923602522,"sku":"BWCS-FF50-1","price":34.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43333923635290,"sku":"BWCS-FF50-2","price":39.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43333923668058,"sku":"BWCS-FF50-3","price":43.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-FF50-1.webp?v=1778213575","url":"https:\/\/batteryweb.com\/products\/sony-dcr-ip220e-replacement-battery-74v-750mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
