Both models run the same voltage rail and connector, so one battery covers both. OEM part numbers LD18650F-1 and LD18650H-1 are direct references for this cell configuration.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eA8 Pro and A8 Pro-92D3 compatibility:\u003c\/strong\u003e\n    Both terminals share the same 7.4V battery bay, connector pinout, and BMS handshake protocol. Swapping between these two variants requires no modification — the charge IC in each model reads the same cell chemistry and capacity data from this pack.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this battery through full charge cycles on a Landi A8 Pro unit and monitored BMS communication, thermal behaviour, and charge acceptance. The protection circuit tripped correctly at undervoltage and recovered cleanly on reconnection to the charger.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst transaction cycle after swap:\u003c\/strong\u003e\n    After fitting this battery, run one complete transaction — including a receipt print — before deploying the terminal in a live environment. The terminal maps cell capacity during normal operation and needs at least one full power cycle to calibrate the charge indicator accurately.\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 A8 Pro's receipt printer draws a sharp current spike the moment it fires — enough to trigger the BMS overcurrent protection on a new cell that hasn't completed its first full charge cycle. The BMS interprets the spike as a fault and cuts output, which the terminal reads as a power loss and reboots. Charge the battery to 100% before the first live use, then run one full transaction cycle including a print. After that initial calibration, the BMS threshold adjusts to the terminal's load profile and the cutoff behaviour stops.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTerminal not completing PCI boot sequence after sitting unused\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA Landi A8 Pro left in a drawer for several months can drop below the cell recovery threshold — typically under 2.5V per cell, or around 5.0V for the pack. At that voltage, the BMS locks output and the terminal either shows a blank screen or halts partway through the PCI integrity check. Connect the terminal to its original charger and leave it undisturbed for at least 90 minutes before attempting to power on — the charge IC uses a trickle pre-charge phase to bring the cell voltage back above the 6.0V recovery threshold before resuming normal charging.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43415921852506,"sku":"BWCS-INA810BL-1","price":40.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43415921885274,"sku":"BWCS-INA810BL-2","price":47.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43415921918042,"sku":"BWCS-INA810BL-3","price":52.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-INA810BL-1.webp?v=1779757951","url":"https:\/\/batteryweb.com\/products\/landi-a8-pro-92d3-replacement-battery-74v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
