It matches OEM part numbers 1811024K1 and M35-402060-JD. The RP750X is a portable card reader used by merchants for wireless credit and debit processing.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eROAM RP750X platform fit:\u003c\/strong\u003e\n    The RP750X uses a compact Li-Polymer cell in a specific 59 × 20 × 4mm form factor. The BMS on this terminal monitors both voltage and temperature. Any replacement cell must meet both the physical envelope and the voltage handshake — this cell does.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through full boot, payment transaction sequences, and wireless pairing on the RP750X. The BMS accepted the cell without fault codes, and the charge indicator tracked correctly across discharge.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst deployment tip:\u003c\/strong\u003e\n    After installation, complete one full transaction cycle before deploying in a live environment. 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\"\u003eTerminal not completing PCI boot sequence after battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe RP750X runs a PCI-compliant boot sequence on every startup that includes a battery voltage check. A new cell sitting at storage charge — typically around 3.6V to 3.7V — can fall just below the threshold the terminal expects before it clears the security check. This causes the device to loop or freeze mid-boot. Plug into the charging dock immediately after installing the new battery and allow the terminal to charge to at least 3.85V before powering on independently. One full boot-charge cycle resolves this in almost every case.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRP750X not powering on after sitting unused in storage\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eLi-Polymer cells self-discharge at roughly 2–3% per month. An RP750X left in a drawer for several months can drop below 3.0V — the point where the BMS locks the cell to prevent further discharge damage. When you press the power button, nothing happens. Place the terminal on charge for at least 30 minutes before attempting to power on. If the screen remains dark after 30 minutes, the dock charger is trickling current into the cell to recover it — leave it another hour before retrying.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43415926112346,"sku":"BWCS-IRP750SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43415926145114,"sku":"BWCS-IRP750SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43415926177882,"sku":"BWCS-IRP750SL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-IRP750SL-1.webp?v=1779757950","url":"https:\/\/batteryweb.com\/products\/ingenico-roam-rp750x-replacement-battery-37v-450mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
