It matches the OEM part number AHB474736B and fits the original battery compartment directly. If your terminal is shutting down unexpectedly or no longer holding a charge, this is the cell that needs replacing.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRP457 and RP457C compatibility:\u003c\/strong\u003e\n    Both models share the same battery bay, connector pinout, and BMS communication protocol. The AHB474736B cell is the correct fit for either variant — no adapter or wiring modification needed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through the RP457's charge IC and confirmed the BMS handshake completes cleanly. The terminal accepted the battery, passed its internal voltage check, and held a stable charge curve through a full cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst deployment tip:\u003c\/strong\u003e\n    After installation, run one complete transaction cycle before putting the terminal into a live environment. The RP457 maps battery capacity during normal operation — at least one full power cycle is required for the charge indicator to read accurately.\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\n  \u003cp class=\"bpw-desc-p\"\u003eThe RP457's BMS monitors current draw continuously. When the receipt printer motor fires or the wireless radio spikes, current demand jumps sharply for a fraction of a second. On a degraded or newly installed cell that hasn't completed a calibration cycle, the BMS can interpret this spike as an overcurrent event and cut power. The fix is to complete several normal transaction cycles before live deployment — this allows the BMS to learn the cell's actual discharge curve and set its trip thresholds correctly. If reboots continue after five full cycles, check that the battery connector is fully seated and the contact pins are clean.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTerminal not completing PCI boot sequence after sitting unused\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eLi-Polymer cells self-discharge slowly over time. If the RP457 has been stored in a drawer for several weeks or months, the cell voltage can drop below the BMS recovery threshold — typically around 2.5V for this chemistry. At that point, the terminal either won't power on at all or stalls partway through the PCI boot sequence. Connect the terminal to its dock or USB-C charger and leave it for at least 30 minutes before attempting to power on. If the charge LED doesn't activate within five minutes of connecting the charger, the cell may be below the recovery floor and will need a replacement.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43415921295450,"sku":"BWCS-INP457SL-1","price":36.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43415921328218,"sku":"BWCS-INP457SL-2","price":42.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43415921360986,"sku":"BWCS-INP457SL-3","price":47.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-INP457SL-1.webp?v=1779757951","url":"https:\/\/batteryweb.com\/products\/ingenico-rp457-replacement-battery-37v-250mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
