It fits the Nurit 8020, Nurit 8020US20, 802B-WW-M05, and M50 variants. All four share the same battery bay, connector pinout, and BMS handshake protocol.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eNurit 8020 series compatibility:\u003c\/strong\u003e\n    The 8020, 8020US20, 802B-WW-M05, and M50 all run the same 7.4V power rail with an identical three-pin connector and BMS communication line. One battery pack covers all four.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through full charge and discharge on a Nurit 8020 unit. The BMS accepted the handshake on first boot, reported state-of-charge correctly, and held voltage above 6.8V through repeated transaction simulations including receipt printer activation.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-deployment tip:\u003c\/strong\u003e\n    After fitting, complete one full transaction cycle before using the terminal in a live environment. The Nurit 8020 maps battery capacity during normal operation and needs at least one complete power cycle to calibrate the charge indicator accurately.\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 voltage sag on the Nurit 8020\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe thermal printer inside the Nurit 8020 draws a sharp current spike every time it activates — typically 800mA to 1.2A for the first half-second. A degraded or deeply discharged battery cannot sustain that draw without the voltage collapsing. When voltage drops below the BMS protection threshold, the terminal cuts power to protect the cell. A fresh battery at full charge holds the voltage rail stable through that printer spike without triggering a cutoff.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTerminal stuck on the PCI boot screen after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Nurit 8020 runs a PCI security handshake during every boot sequence. If the BMS on a new battery has not yet completed its first full charge acceptance cycle, it can report an ambiguous state-of-charge to the terminal's firmware, stalling the boot. This is not a fault with the battery or the terminal. Charge the battery fully to 8.4V using the original dock, then power the terminal on — one complete charge cycle resolves the stall in nearly all cases.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43415940857946,"sku":"BWCS-VFT802BL-1","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43415940890714,"sku":"BWCS-VFT802BL-2","price":35.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43415940923482,"sku":"BWCS-VFT802BL-3","price":38.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-VFT802BL-1.webp?v=1779758254","url":"https:\/\/batteryweb.com\/products\/verifone-nurit-8020-replacement-battery-74v-1800mah-lithium","provider":"BatteryWeb","version":"1.0","type":"link"}
