It slots into the rear battery bay and powers the full terminal stack — display, wireless radio, and receipt printer. Capacity figure is 19.24Wh as rated in the product specification.\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 uses a 7.4V two-cell Li-ion pack with a BMS that handshakes with the terminal's charge IC on first boot. Voltage rail and connector pinout match the OEM pack so the terminal completes its power-on sequence without errors.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through simulated transaction loads — printer motor pulls, Wi-Fi bursts, and display-on states — and the BMS held the voltage rail steady without triggering overcurrent cutoff during any draw spike.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst deployment tip for the OM-A880:\u003c\/strong\u003e\n    After installing this battery, complete one full transaction cycle before taking the terminal into a live environment. The OM-A880 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\"\u003ePayment terminal rebooting mid-transaction after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe OM-A880 receipt printer draws a sharp current spike the moment it feeds paper — often 1.5A or more for under a second. On a new battery that hasn't completed a full charge-discharge cycle, the BMS can read this spike as an overcurrent fault and cut the output rail. The terminal loses power mid-transaction and reboots. Run the battery through one full charge cycle and process a test transaction before live deployment — this allows the BMS to learn the load profile and stop tripping on normal printer draws.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eOM-A880 won't power on after sitting unused in a drawer\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge at roughly 1–3% per month. A terminal left unused for several months can drop the cell voltage below 2.5V per cell — the threshold where most BMS circuits lock the output to prevent damage. The terminal shows nothing when you press the power button, which looks like a dead battery or a hardware fault. Place the terminal on charge for at least 30 minutes without pressing any buttons; the charger applies a low-current trickle that nudges the cell voltage back above the BMS recovery threshold, typically 2.8–3.0V per cell, before normal charging resumes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43415937744986,"sku":"BWCS-NEP8210BL-1","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43415937777754,"sku":"BWCS-NEP8210BL-2","price":35.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43415937810522,"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\/magnati-om-a880-replacement-battery-74v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
