It fits the T650p directly using the same connector and BMS communication protocol as the factory unit. Capacity figures come from the product data: 3350mAh \/ 24.79Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eT650p platform fit:\u003c\/strong\u003e\n    The T650p uses a 2S1P 18650 cell arrangement to hit the 7.4V nominal rail. The terminal's charge IC expects a specific BMS handshake on that rail — a mismatched pack will show a fault code rather than charge. This replacement uses the same cell configuration and BMS profile.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through the T650p's charge IC and confirmed the BMS handshake completed without fault codes. The protection circuit responded correctly to simulated overcurrent during a receipt-print draw spike and recovered cleanly.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-deployment cycle on the T650p:\u003c\/strong\u003e\n    After fitting this battery, run one complete transaction — card tap or swipe through to receipt print — before putting the terminal into a live environment. The T650p maps battery capacity during normal operation and needs at least one full power cycle to display 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 not completing PCI boot sequence after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe T650p runs a PCI security boot sequence on every power-on that includes a handshake with the battery BMS. On a brand-new replacement pack, the charge IC may not have completed its first acceptance cycle, causing the boot sequence to stall or loop. This is not a fault with the terminal or the battery — it is the charge IC in pre-acceptance mode. Plug the terminal into mains power, let it reach a full charge state, then cold-boot. After one complete charge cycle, the BMS handshake is accepted and the PCI sequence completes normally.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator stuck at 99% after installing a new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA battery indicator locked at 99% on first charge is the T650p's charge IC operating in top-off mode on a new cell — it is not a defect. The IC holds the pack in a slow top-off phase until the cell voltage stabilises at the full-charge threshold, typically 8.40V across the 2S stack. Once that threshold is held for the required dwell time, the indicator steps to 100% and the IC switches to standby. If the indicator has not moved after 90 minutes on charge, disconnect mains, power the terminal off fully, reconnect mains, and allow a fresh charge cycle to begin from a cold state.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43415922704474,"sku":"BWCS-VFP650BX-1","price":50.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43415922737242,"sku":"BWCS-VFP650BX-2","price":59.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43415922770010,"sku":"BWCS-VFP650BX-3","price":66.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-VFP650BX-1.webp?v=1779757974","url":"https:\/\/batteryweb.com\/products\/verifone-t650p-replacement-battery-74v-3350mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
