It matches the original connector, cell count, and voltage rail the T58 series expects at the BMS handshake. Capacity figures come from product data — not web estimates.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eT58 series compatibility:\u003c\/strong\u003e\n    The T58-Tix, T58-G3, T58-T1C, and T58-T1 share the same 3S Li-ion architecture, connector pinout, and BMS communication protocol. Any T58 variant on this listing will seat and negotiate correctly without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge cycles on T58 hardware and confirmed the BMS handshake completes at first boot. The protection circuit trips correctly at low-voltage cutoff and clears on reconnect — no persistent fault codes recorded.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the T58:\u003c\/strong\u003e\n    After fitting this cell, run a full discharge to hibernate cutoff, then charge uninterrupted to 100% without unplugging. This forces the BIOS battery learn cycle to reset against the new cell's actual capacity 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\"\u003eWhy the T58 BIOS flags a new battery as poor health immediately after swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe T58 BIOS stores battery health data in EEPROM tied to the original cell's cycle count and rated Wh. When a new cell is installed, that stored data does not automatically reset — the BIOS reads the mismatch and reports degraded health even though the cell is brand new. This is a firmware bookkeeping issue, not a physical fault. Run one full discharge-to-hibernate followed by an uninterrupted charge to 100% and the learn cycle will overwrite the stale EEPROM values.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eT58 shutting down at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC has not yet calibrated against the new cell's actual voltage curve. The gauge reports 25% remaining while the cell voltage has already dropped below the BMS cutoff threshold under combined CPU and display load — the laptop shuts off because the hardware sees undervoltage, not because the percentage is accurate. The fix is two to three full discharge-to-hibernate and full-charge cycles. After those calibration cycles, the fuel gauge tracks the real cell voltage correctly and the early shutdowns stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409601495130,"sku":"BWCS-CLN855NB-1","price":73.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409601527898,"sku":"BWCS-CLN855NB-2","price":86.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409601560666,"sku":"BWCS-CLN855NB-3","price":95.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CLN855NB-1.webp?v=1779580170","url":"https:\/\/batteryweb.com\/products\/machenike-t58-tix-replacement-battery-111v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
