It matches the original form factor at 70.10 × 23.45 × 6.50mm and slots into the camera body without modification. Capacity figure is 950mAh (3.52Wh) — taken from the cell specification, not estimated.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEX-V7 and EX-V8 series compatibility:\u003c\/strong\u003e\n    All four models in this fit list share the same NP-50 battery bay, voltage rail, and connector pinout. The BMS handshake across this series reads the same cell identification, so one replacement cell covers the full group.\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 the EX-V8 platform. The BMS accepted the cell without error flags, and the protection circuit triggered correctly at the low-voltage cutoff threshold — no runaway discharge observed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use charge cycle on EX-V8SR:\u003c\/strong\u003e\n    Insert the new cell and charge it fully inside the camera body or OEM charger before your first shoot. The Exilim BMS maps its battery-remaining display to a discharge curve it calibrates on the first full cycle — skipping this step causes the indicator to read inaccurately for several sessions.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFlash recycling lag on a new NP-50 cell near the end of charge\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Exilim EX-V8SR flash capacitor draws a sharp recharge current after each shot. When the cell voltage drops toward the lower end of its discharge curve — typically below 3.5V under load — that capacitor recharge current causes a brief voltage sag. The camera's processor detects the sag and slows the recycling cycle to protect the cell. You'll notice the flash-ready indicator taking longer between shots even though the battery indicator still shows partial charge. This is normal BMS behaviour, not a fault — it means the cell is approaching its cutoff window.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically on the EX-V8SR display\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Exilim BMS maps its on-screen percentage to a voltage-threshold table calibrated for the original NP-50 discharge curve. A replacement cell with a slightly different internal resistance will follow a marginally different voltage curve under load, so the displayed percentage can jump — for example, from 60% to 30% in a single burst of shots. This is a display calibration mismatch, not a capacity fault. Run two full charge-discharge cycles through the camera body and the BMS will re-map its thresholds to the new cell's actual curve.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333862228058,"sku":"BWCS-NP50CA-1","price":22.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43333862260826,"sku":"BWCS-NP50CA-2","price":25.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43333862293594,"sku":"BWCS-NP50CA-3","price":27.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NP50CA-1.webp?v=1778213291","url":"https:\/\/batteryweb.com\/products\/casio-exilim-ex-v8sr-replacement-battery-37v-950mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
