It fits merchants running the OM-A880 for card-present transactions in retail, hospitality, and field service environments. Same voltage rail and connector footprint as the factory cell.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOM-A880 platform fit:\u003c\/strong\u003e\n    The OM-A880 runs a single-cell 7.4V nominal rail shared across its display, wireless module, and receipt printer. This replacement matches that rail exactly, so the terminal's power management IC doesn't flag a voltage mismatch on boot.\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-discharge sequences and monitored the BMS response during simulated printer-motor draw spikes. The protection circuit held without tripping at normal operating loads.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst transaction cycle before live deployment:\u003c\/strong\u003e\n    After fitting this battery, run the terminal through at least one complete boot and transaction cycle before using it at the counter. The OM-A880 maps battery capacity during normal operation — the charge indicator won't read accurately until that initial calibration cycle completes.\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 OM-A880 runs a PCI-compliant tamper-detection check on every power-up. If the battery voltage hasn't stabilised after installation, the terminal can stall partway through that sequence and refuse to reach the home screen. New cells sometimes sit at a partial state of charge after shipping. Charge the replacement battery to full — confirmed by the terminal showing 100% — before attempting to boot into a live payment session. One complete charge cycle is usually enough for the BMS handshake to be accepted by the terminal's security controller.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery indicator stuck at 99% through a full first charge\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eA new Li-ion cell triggers the terminal's charge IC to enter top-off mode rather than reporting a clean 100% on the first pass. The charge controller holds the indicator just below full while it trickle-charges the cell to its actual ceiling voltage of 8.4V. This is normal behaviour and not a fault with the battery or the terminal. Leave the terminal on charge until it drops out of top-off mode on its own — the indicator will flip to 100% and charging current will stop automatically.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43415937843290,"sku":"BWCS-NEP8210BL-1","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43415937876058,"sku":"BWCS-NEP8210BL-2","price":35.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43415937908826,"sku":"BWCS-NEP8210BL-3","price":38.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NEP8210BL-1.webp?v=1779758086","url":"https:\/\/batteryweb.com\/products\/geidea-om-a880-replacement-battery-74v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
