It replaces OEM part BPK169-001-01-A. Merchants use this cell to restore a terminal that no longer holds charge through a full shift or transaction period.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVeriFone wireless terminal compatibility:\u003c\/strong\u003e\n    VeriFone wireless POS units in this line share a common 7.4V two-cell Li-ion architecture with a BMS that validates cell voltage and temperature before the terminal completes its boot sequence. The connector and BMS handshake must match — this battery meets both requirements for BPK169-001-01-A applications.\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-charge sequence and ran it under combined wireless, display, and receipt printer draw. The BMS held stable across the load spikes from the printer motor and did not trip an overcurrent cutoff during transaction simulation.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst deployment tip:\u003c\/strong\u003e\n    After installing this battery, complete one full transaction cycle before putting the terminal into live service. The terminal maps battery capacity during normal operation and needs at least one complete power cycle 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\"\u003ePayment terminal rebooting mid-transaction after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA receipt printer motor pulls a short, sharp current spike — often 1.5A or more above idle draw — at the moment it fires. If the BMS on a new battery has not yet completed its first full calibration cycle, it can interpret that spike as an overcurrent event and cut power. This resets the terminal mid-sale. Running one complete transaction cycle after installation allows the BMS to establish baseline load profiles and stops false overcurrent trips from recurring.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTerminal not powering on after sitting unused in a drawer\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge at roughly 2–3% per month. A terminal stored for several months can arrive with a cell voltage below the BMS recovery threshold — typically around 2.5V per cell. At that point the BMS locks output to protect the cell, and the terminal shows no response at all. Connect the terminal to its dock or charging cable and leave it for 20–30 minutes before pressing power — most VeriFone chargers apply a low-current trickle that brings the cell back above the 2.8V recovery floor and allows the BMS to release the output lock.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43415933321306,"sku":"BWCS-VFR200BX-1","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43415933354074,"sku":"BWCS-VFR200BX-2","price":38.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43415933386842,"sku":"BWCS-VFR200BX-3","price":42.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-VFR200BX-1.webp?v=1779758145","url":"https:\/\/batteryweb.com\/products\/verifone-replacement-battery-74v-3400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
