It fits the Cyber-shot DSC-P12, DSC-P8, DSC-P3, DSC-FX77, and 13 additional Cyber-shot compact models. Same voltage, same form factor, same connector as the original Sony cell.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eShared platform across Cyber-shot P and FX bodies:\u003c\/strong\u003e\n    These compact Cyber-shot models share the same 3.7V rail and NP-FC10 connector footprint. The BMS handshake and cell dimensions are consistent across the entire group, so one replacement cell covers the full lineup without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through full charge and discharge cycles on a Cyber-shot body. The BMS accepted the cell without a rejection flag, held voltage steadily through the discharge curve, and cut off cleanly at low-cell threshold — no false low-battery warnings mid-cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle initialisation on Cyber-shot bodies:\u003c\/strong\u003e\n    Charge this cell inside the camera body using the OEM charger on the first use. Some Cyber-shot BMS firmware maps the battery-remaining display against a charge reference taken at initial acceptance — skipping this step can cause the indicator to read inaccurately until one full in-body cycle completes.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSony Cyber-shot BMS authentication check on third-party cells\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSony Cyber-shot compact bodies run a brief BMS check when a new cell is inserted. If the camera does not recognise the cell on first install, it may display a battery error or refuse to power on. This is not a fault with the cell — it is the body querying the cell's voltage response before accepting it. Placing the battery in the OEM charger for a partial charge first, then inserting it into the body, resolves the check in most cases.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping or dropping suddenly on Cyber-shot display\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe DSC-P12 and related bodies use a voltage-threshold system to estimate remaining charge — they do not track coulombs. A new replacement cell has a slightly different discharge curve than the aged OEM cell the camera was calibrated against, so the indicator can skip between levels or drop sharply near the end of discharge. This is a display mapping issue, not a capacity fault. Run two full charge and discharge cycles through the camera body and the indicator will stabilise as the BMS maps thresholds against the new cell's actual curve.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333919637594,"sku":"BWCS-FC10-1","price":23.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43333919670362,"sku":"BWCS-FC10-2","price":26.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43333919703130,"sku":"BWCS-FC10-3","price":29.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-FC10-1.webp?v=1778213575","url":"https:\/\/batteryweb.com\/products\/sony-cyber-shot-dsc-p12-replacement-battery-37v-650mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
