It replaces OEM part numbers 0B200-02120000, 0B200-02120100, AD2068520, and C12N1604. Fits the T101HA, T101HA-3D, T101HA-3E, and over fifty additional T101HA variants.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eT101HA platform compatibility:\u003c\/strong\u003e\n    All T101HA variants share a single battery bay, connector pinout, and BMS handshake protocol. The voltage rail and EEPROM data structure are identical across the 3D, 3E, and M0I sub-models, so one cell covers the full range without hardware modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through full charge and discharge cycles on the T101HA platform. The BMS communicated correctly with the BIOS, charge termination triggered cleanly at capacity, and the protection circuit responded to over-current conditions without nuisance tripping.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the T101HA:\u003c\/strong\u003e\n    After fitting this cell, run the laptop down to hibernate cutoff under normal use, then charge uninterrupted to 100% without interruption. This resets the BIOS battery learn cycle and clears the false \"poor health\" warning that appears after every cell swap on this platform.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the T101HA BIOS reports poor battery health after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe T101HA stores battery health data in EEPROM on the original cell. When a new cell is installed, the BIOS reads residual EEPROM values from its own learned history and flags the battery as degraded before it has run a single cycle. This is a firmware behaviour, not a fault with the replacement cell. Running one full discharge-to-hibernate followed by an uninterrupted charge to 100% gives the BIOS enough data to overwrite the stale health flag. After two to three calibration cycles, the reported health figure stabilises.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down at 20–30% charge shown on the T101HA\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 discharge curve. The OS shows 20–30% remaining, but the IC has mapped that reading against the old cell's degraded profile, so the voltage reading hits the shutdown threshold earlier than expected. It is not a cell defect — the gauge needs two or three full discharge-to-hibernate cycles to relearn the new curve. After calibration, the shutdown point drops back to the correct low-voltage cutoff near 3.0V per cell.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409660510298,"sku":"BWCS-AUT103NB-1","price":78.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409660543066,"sku":"BWCS-AUT103NB-2","price":93.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409660575834,"sku":"BWCS-AUT103NB-3","price":103.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AUT103NB-1.webp?v=1779580339","url":"https:\/\/batteryweb.com\/products\/asus-t101-m0i-replacement-battery-385v-8200mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
