It fits the DCR-PC5E, DCR-PC3E, DCR-PC1, DCR-PC2E, and several other models in the same physical battery family. Capacity is 2880mAh (10.66Wh) — drawn from product specification, not estimated.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eNP-FS series compatibility:\u003c\/strong\u003e\n    The DCR-PC1 through PC5E share the same slim NP-FS form factor, voltage rail, and connector pinout. All three OEM part numbers — NP-FS20, NP-FS21, and NP-FS22 — are interchangeable across this camcorder range because Sony used the same physical slot and BMS handshake protocol throughout the lineup.\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 hardware. The BMS accepted the cell without fault flags, reported charge state without interruption, and held voltage within spec across the full discharge curve from 4.2V down to the 3.0V cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge on these camcorders:\u003c\/strong\u003e\n    Charge this battery fully inside the camcorder body or Sony OEM charger before your first recording session. The DCR-PC series BMS maps battery-remaining display thresholds during the initial charge cycle — skipping this step causes the indicator to read inaccurately throughout use.\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-PC5E shows a dead battery indicator on a partially charged replacement cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eSony's MiniDV camcorders from this era use a voltage-threshold map stored in the BMS to translate cell voltage into the on-screen battery bar. A new replacement cell has a slightly different discharge curve profile than a worn OEM cell the camera learned from. When the thresholds don't match, the camera reads a partially charged cell as empty and refuses to operate. Running one full charge cycle inside the camera body — from flat to 4.2V — recalibrates the threshold map to the new cell and restores accurate indicator behaviour.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCamera body showing \"no battery\" on a valid installed cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the BMS authentication check doesn't complete on first insertion — a known behaviour on the DCR-PC series with new third-party cells. The cell is not faulty; the handshake simply timed out. Remove the battery, wait ten seconds, and reinsert it firmly until the latch clicks. If the error persists, place the battery in an OEM-compatible charger until it reads full charge (4.2V), then reinsert into the camera body.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333923864666,"sku":"BWCS-FS21-1","price":40.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333923897434,"sku":"BWCS-FS21-2","price":46.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333923930202,"sku":"BWCS-FS21-3","price":51.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-FS21_1.webp?v=1778213576","url":"https:\/\/batteryweb.com\/products\/sony-dcr-pc5e-replacement-battery-37v-2880mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
