Both models share the same battery bay, connector, and BMS handshake protocol. Capacity figures here come from the product specification — 11.1Wh total energy.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eI7810 and I7910 compatibility:\u003c\/strong\u003e\n    Both terminals run the same 7.4V voltage rail, use the same physical connector, and negotiate with the same charge controller. One cell fits both without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the I7910 charge controller and confirmed the BMS handshake completed cleanly — no error flags, no rejected authentication on first boot.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst deployment cycle:\u003c\/strong\u003e\n    After installing the battery, run at least one complete transaction — including a receipt print — before using the terminal on a live sales floor. The terminal maps battery capacity during normal operation and needs one full 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\"\u003eTerminal rebooting mid-transaction after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe I7810 and I7910 receipt printer draws a short, high-current pulse when the print head fires. On a new cell, the BMS protection threshold can trip on this spike if the battery has not yet completed its first full charge-discharge cycle. The overcurrent event looks like a random reboot but happens consistently at the point the printer activates. Charge the replacement battery fully before first use — verified full charge on this cell is 8.4V at the terminals.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTerminal stuck at 99% charge indicator after installing this battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new Li-ion cell arrives partially charged. When you plug in the dock, the charge IC enters top-off mode rather than a full charge cycle, so the indicator stops near 99% and stays there. This is the charge controller doing its job — it sees a cell near capacity and trickle-charges rather than cycling. Leave the terminal docked for an additional 30–45 minutes after the indicator appears full, then power cycle the unit. The gauge recalibrates and reads correctly from that point.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43415940366426,"sku":"BWCS-INC7910BL-1","price":44.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43415940399194,"sku":"BWCS-INC7910BL-2","price":51.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43415940431962,"sku":"BWCS-INC7910BL-3","price":57.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-INC7910BL-1.webp?v=1779758202","url":"https:\/\/batteryweb.com\/products\/ingenico-i7810-replacement-battery-74v-1500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
