It replaces OEM part EU383450P and restores wireless operation for card-present transactions in retail and hospitality settings. Capacity is 2.41Wh — identical to the original cell specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMOBY8500 fit confirmation:\u003c\/strong\u003e\n    The MOBY8500 uses a flat Li-Polymer cell at 3.7V nominal with a specific connector and BMS handshake. This replacement matches the OEM footprint at 52.00 × 33.60 × 3.80mm and communicates correctly with the terminal's charge controller so the fuel gauge reports accurately.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the MOBY8500's full charge-discharge loop and confirmed the BMS accepted the new cell without overcurrent trips or error flags on the terminal's status screen.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-deploy cycle tip:\u003c\/strong\u003e\n    After fitting this battery, run one complete transaction — from power-on through card read and receipt print — before putting the terminal into live service. The MOBY8500 maps battery capacity during normal operation and needs at least one full power cycle to report 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 fresh Li-Polymer cell has higher internal impedance until it completes its first few charge-discharge cycles. On the MOBY8500, the combined current draw from the receipt printer motor and the contactless radio during a tap transaction can spike briefly above what the BMS expects from an unconditioned cell. If the BMS reads that spike as an overcurrent event, it cuts power and the terminal reboots. Running two or three low-load transactions first — chip-and-PIN without printing — conditions the cell and lowers impedance enough to handle the full combined draw cleanly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTerminal not completing PCI boot sequence on new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe MOBY8500 runs a security integrity check during boot that requires stable voltage throughout. If the new cell shipped at low state-of-charge, voltage can sag below the boot threshold partway through the PCI sequence and the terminal stalls or shows a blank screen. Connect the terminal to its charging cable before pressing power — wait until the charge LED is solid, not blinking, then boot. The cell needs to reach at least 3.85V before the boot sequence will complete without interruption.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43415926571098,"sku":"BWCS-IMB850SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43415926603866,"sku":"BWCS-IMB850SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43415926636634,"sku":"BWCS-IMB850SL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-IMB850SL-1.webp?v=1779757951","url":"https:\/\/batteryweb.com\/products\/ingenico-moby8500-replacement-battery-37v-650mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
