It also fits PCA169-404-01-A and PCA169-001-01 terminal configurations. The cell, connector, and BMS profile match the original so the terminal's charge management system accepts the replacement without error codes.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRuby 2 and Ruby CI compatibility:\u003c\/strong\u003e\n    Both terminals share the same 7.4V battery bay, connector pinout, and BMS handshake protocol. The charge IC in each unit communicates with the battery's protection circuit the same way, so one cell works across both platforms without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge and discharge on a Ruby 2 unit. The BMS accepted the handshake on first boot, the charge indicator updated correctly, and the protection circuit responded to load spikes from the receipt printer without tripping.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst deployment tip for POS terminals:\u003c\/strong\u003e\n    After installation, complete one full transaction cycle before putting the terminal into a live lane. The Ruby 2 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\"\u003eTerminal rebooting mid-transaction after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Ruby 2's receipt printer draws a sharp current spike the moment it fires — often 1.5A or more for a fraction of a second. If the BMS on a new cell hasn't completed its initial calibration cycle, that spike can trip the overcurrent protection and cut power mid-transaction. This is not a faulty battery. Run the terminal through two or three complete charge-discharge cycles before heavy use. Once the protection circuit has mapped normal load behaviour, nuisance trips stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTerminal stuck at 99% charge indicator for hours after a full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNew lithium cells ship at a partial state of charge. When first placed on charge, the Ruby 2's charge IC enters a top-off phase once the cell reaches roughly 4.1V per cell — the indicator reads 99% and holds there while the controller trickle-charges to 4.2V. This is normal charge IC behaviour, not a stuck sensor. The indicator moves to 100% and the terminal switches to maintenance mode once the top-off threshold is met, typically after the cell voltage stabilises at 8.4V total.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43415925588058,"sku":"BWCS-VFR200BL-1","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43415925620826,"sku":"BWCS-VFR200BL-2","price":35.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43415925653594,"sku":"BWCS-VFR200BL-3","price":38.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/batteryweb.com\/products\/verifone-ruby-2-replacement-battery-74v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
