It fits the OM-A880 directly, matching the original connector, voltage rail, and BMS communication protocol. Capacity is 2600mAh (19.24Wh), identical to the factory specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOM-A880 fit and connector:\u003c\/strong\u003e\n    The OM-A880 uses a fixed 7.4V two-cell Li-ion configuration with a dedicated BMS handshake line. This replacement matches that pinout and voltage rail exactly — the terminal's charge IC recognises the pack and enters normal charge mode without fault codes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through full charge, idle standby, and active transaction loads including simultaneous receipt printing and wireless connectivity. The BMS held stable across all draw profiles with no overcurrent trips or voltage drop events.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-deployment cycle on the OM-A880:\u003c\/strong\u003e\n    After installation, run at least one complete transaction cycle before going live — the terminal maps battery capacity during normal operation and needs one full power cycle to calibrate the charge indicator correctly. Deploying before this step often causes the charge gauge to display inaccurate percentages.\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 on a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe OM-A880 runs a BMS handshake check early in its PCI boot sequence. On a new pack, the BMS may not yet have a recognised charge history, causing the terminal to stall or loop before reaching the home screen. This is not a fault with the battery — it is the terminal waiting for the pack to complete its first full charge-discharge acknowledgement. Charge the terminal to 100%, power it off, then power it back on to complete the handshake. The boot sequence proceeds normally after that first full cycle.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTerminal reboots mid-sale during receipt printing\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe OM-A880's receipt printer draws a short high-current spike when the print head fires — this can push instantaneous draw beyond what a degraded or deeply discharged pack can sustain, triggering a BMS overcurrent cutoff and resetting the terminal. On a new replacement pack, this reboot pattern at the point of print usually means the cell has not yet reached full resting voltage after installation. Charge the unit fully to 4.2V per cell (8.4V pack total) before the first live transaction. If reboots continue after a full charge, confirm the terminal firmware is current — some OM-A880 firmware versions have a known print-current threshold that requires an update.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43415937646682,"sku":"BWCS-NEP8210BL-1","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43415937679450,"sku":"BWCS-NEP8210BL-2","price":35.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43415937712218,"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\/oma-emirates-om-a880-replacement-battery-74v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
