It matches the OEM voltage rail, physical dimensions (75.40 × 50.30 × 21.70mm), and connector spec needed for the terminal to boot and hold a charge during field operation.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eNurit 8040 \/ 8400 \/ 8400 PCI platform:\u003c\/strong\u003e\n    All three models share the same battery bay geometry, 7.4V supply requirement, and BMS handshake protocol. One cell fits all three without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through a full boot sequence on a Nurit 8400 unit. The BMS accepted the cell without fault codes, the charge IC entered top-off mode at 8.35V, and the terminal completed PCI POST without interruption.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-deployment calibration:\u003c\/strong\u003e\n    After fitting this battery, run at least one complete transaction cycle — print a receipt, process a card — before putting the terminal on a live counter. The terminal maps battery capacity during normal operation and needs that activity to calibrate the charge indicator correctly.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eReceipt printer causing mid-transaction battery drain on the Nurit 8040\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Nurit 8040's thermal printer motor draws a short but sharp current spike when it fires — often 1.5A to 2A above idle draw. On a degraded original battery, that spike pushes the cell voltage below the BMS low-voltage trip threshold, and the terminal cuts power mid-transaction. A fresh 2200mAh cell with lower internal resistance handles that spike without the voltage sag that triggers the trip. If reboots are happening specifically at the point a receipt prints, the battery is the first thing to rule out.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTerminal not completing PCI boot sequence after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Nurit 8400 PCI Compliant model runs a security POST at startup that draws sustained current while validating tamper-detection hardware. If the battery was just installed and the cell hasn't gone through a full charge cycle, the charge IC may still be in pre-charge conditioning mode and can't sustain that load cleanly. The terminal stalls or loops at the boot screen. Fix: charge the battery fully until the charge LED goes green, then power the terminal on. Once the cell reaches 8.35V resting voltage, the boot sequence completes normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43415940464730,"sku":"BWCS-VFT804BL-1","price":37.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43415940497498,"sku":"BWCS-VFT804BL-2","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43415940530266,"sku":"BWCS-VFT804BL-3","price":47.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-VFT804BL_1.webp?v=1779758255","url":"https:\/\/batteryweb.com\/products\/verifone-nurit-8040-replacement-battery-74v-2200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
