It replaces OEM part numbers SQU-902, SQU-914, 916T2017F, CQB901, CQBP901, and CQB904. If the original cell no longer holds a charge or the laptop only runs when plugged in, this is the direct replacement.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eT6-I5430M and Super T6-I5430M fitment:\u003c\/strong\u003e\n    Both models share the same battery bay dimensions, connector pinout, and BMS handshake protocol. The same 11.1V cell fits both without modification — the Super variant uses identical hardware at the battery interface level.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on compatible Hasee hardware. The BMS communicated correctly with the system board, accepted a full charge without cutoff errors, and discharged without triggering undervoltage protection prematurely.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration cycle:\u003c\/strong\u003e\n    After fitting this battery, run one full discharge down to hibernate-cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears in the OS after any 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 installation\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis is an EEPROM data mismatch, not a fault with the new cell. The BIOS reads health metrics stored in the old battery's EEPROM and compares them against the new cell's charge behaviour — they don't match, so it flags the battery as degraded. Running a full discharge-to-hibernate followed by an uninterrupted charge to 100% allows the BIOS to complete its battery learn cycle. After one or two of these cycles, the health reading normalises. No driver update or BIOS flash is required.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down at 20–30% charge shown on the fuel gauge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC in the T6-I5430M calculates remaining capacity based on voltage curves from the original cell. A new cell has a different voltage-to-capacity curve, so the gauge loses accuracy before the cell is calibrated. Under full CPU and display load, the cell voltage drops faster than the uncalibrated gauge predicts — the system hits its low-voltage cutoff while the gauge still reads 20–30%. Run two full discharge-to-hibernate and full recharge cycles. After calibration, the gauge tracks accurately and the cutoff aligns with the correct voltage floor of approximately 9.0V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409810358362,"sku":"BWCS-LXA410NB-1","price":104.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409810391130,"sku":"BWCS-LXA410NB-2","price":119.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409810423898,"sku":"BWCS-LXA410NB-3","price":130.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LXA410NB-1.webp?v=1779581043","url":"https:\/\/batteryweb.com\/products\/hasee-t6-i5430m-replacement-battery-111v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
