It fits the CR-HC51E, DCR-30, DCR-DVD92, DCR-DVD92E, and over 220 additional Sony camcorder and camera models. Cell capacity matches OEM spec at 16.28Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBroad Sony camcorder compatibility:\u003c\/strong\u003e\n    These models share the same 7.4V rail, InfoLITHIUM communication protocol, and physical connector pinout — which is why a single NP-FH90 cell spans such a wide model range without voltage or fit issues.\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 compatible Sony bodies. The BMS handshook correctly, the InfoLITHIUM percentage readout initialised, and protection circuits tripped at the expected low-voltage threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use charge cycle on CR-HC51E and DCR series bodies:\u003c\/strong\u003e\n    Run the first charge from inside the camera body using the OEM charger or USB connection — not a third-party external charger. The Sony BMS maps its battery-remaining display against the cell's discharge curve during this initial cycle. Skipping it causes erratic percentage readings 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 authentication and why new cells get rejected on first install\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eSony's InfoLITHIUM system does more than report percentage — it actively handshakes with the cell over the data pin before allowing the body to draw current. A brand-new cell that has never been through a full charge cycle on that specific body can fail this handshake and throw an incompatible or no-battery warning. The fix is straightforward: seat the battery, insert it into the charger or camera, and let it complete one full charge cycle without interruption. After that single cycle, the body maps the cell and the warning clears. This is a BMS initialisation step, not a fault with the replacement cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping or resetting during recording\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen the Sony body's stored discharge curve doesn't match the new cell's actual voltage-versus-capacity profile, the percentage indicator recalculates mid-session and jumps — sometimes dropping 20% in seconds or resetting to a higher number. This happens because the body interpolates remaining capacity from voltage thresholds it learned from the previous cell. Two full charge-discharge cycles on the body recalibrates the map. After the second cycle, the indicator tracks steadily from 100% down to the 6.8V low-voltage cutoff.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333918228570,"sku":"BWCS-FH90D-1","price":35.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333918261338,"sku":"BWCS-FH90D-2","price":41.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333918294106,"sku":"BWCS-FH90D-3","price":45.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-FH90D-1.webp?v=1778213575","url":"https:\/\/batteryweb.com\/products\/sony-cr-hc51e-replacement-battery-74v-2200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
