It replaces OEM part number A3222-H34. The connector and BMS handshake match the original pack, so the laptop recognises the cell on first boot.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eE400-I3 and R430 platform fit:\u003c\/strong\u003e\n    These three models share the same 10.8V rail, identical connector pinout, and the same BMS communication protocol. One cell covers all three without any adapter or firmware change.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge, discharge, and a simulated CPU-plus-display load. The BMS held the voltage stable across the draw curve and tripped cutoff at the correct low-voltage threshold without false shutdowns.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle calibration on the E400-I3:\u003c\/strong\u003e\n    After installing, discharge the laptop normally to hibernate cutoff, then charge uninterrupted to 100% without unplugging early. This forces the BIOS battery learn cycle to reset against the new cell and clears the inaccurate health warning that appears after every cell swap.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reporting poor battery health immediately after fitting the A3222-H34\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe BIOS pulls health data from EEPROM values written by the original cell. When a new cell goes in, those stored values no longer match the actual chemistry, so the health indicator shows poor or unknown before any real degradation has occurred. This is a firmware read issue, not a fault with the replacement cell. Running one full discharge-to-hibernate followed by an uninterrupted charge to 100% triggers the learn cycle and overwrites the stale EEPROM data. After one or two full cycles, the BIOS health display should return to normal.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFounder R430 shutting down suddenly while the fuel gauge still shows 20–30%\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the cell voltage drops below the BMS cutoff threshold under combined CPU and display load, even though the OS fuel gauge still reads 20–30%. The fuel gauge IC is calibrated against the old cell's discharge curve and misjudges where the actual voltage cliff is on the new pack. The laptop cuts power because the BMS correctly protects the cell — the gauge just hasn't caught up yet. Run two full discharge-to-hibernate and full recharge cycles; the fuel gauge IC recalibrates against the new cell and the premature shutdowns stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409804591194,"sku":"BWCS-AUH13NB-1","price":116.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409804623962,"sku":"BWCS-AUH13NB-2","price":133.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409804656730,"sku":"BWCS-AUH13NB-3","price":146.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AUH13NB-1.webp?v=1779580970","url":"https:\/\/batteryweb.com\/products\/founder-e400-i3-replacement-battery-108v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
