It slots into the battery bay and connects to the same charge controller used by the original cell. No OEM part number is published for this series, so fitment is confirmed against physical dimensions and voltage rail.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eG10 and ZX10 series compatibility:\u003c\/strong\u003e\n    These models share the same 11.1V three-cell voltage rail, connector pinout, and BMS handshake protocol — which is why one cell works across all of them. The charge controller reads cell chemistry and capacity from the battery's EEPROM. As long as that data matches what the BIOS expects, the system charges and reports normally.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge and discharge on a Hasee G10-series unit. The BMS completed the protection handshake without fault codes, charge termination fired correctly at 12.6V, and the fuel gauge IC accepted the new cell data after one calibration cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle reset after install:\u003c\/strong\u003e\n    After fitting this battery, run one full discharge down to hibernate cutoff, then charge uninterrupted to 100%. This forces the BIOS battery learn cycle to run against the new cell's actual capacity curve and clears the inaccurate 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 BIOS reports poor battery health immediately after fitting a new cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Hasee G10 platform stores battery health data in the old cell's EEPROM. When you swap the cell, the BIOS reads the new EEPROM — which contains factory baseline data, not a matched history for your system — and flags a mismatch. This is not a fault with the replacement cell. Running one complete discharge-to-hibernate followed by an uninterrupted charge to 100% triggers the BIOS learn cycle to rewrite the health baseline against the new cell's actual chemistry. After that cycle, the health warning clears and the reported capacity aligns with the 5400mAh rating.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down at 20–30% remaining after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC hasn't yet calibrated against the new cell's voltage curve. Under full CPU and display load, the cell voltage drops faster than the old discharge model predicts — the system reads this as a critical low and cuts power before the gauge catches up. It is not a cell fault. Run two or three full discharge-to-hibernate and charge-to-100% cycles without interruption. By the third cycle the fuel gauge IC has enough data points to track voltage sag accurately, and the phantom shutdowns stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409540284506,"sku":"BWCS-CLH571NB-1","price":88.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409540317274,"sku":"BWCS-CLH571NB-2","price":104.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409540350042,"sku":"BWCS-CLH571NB-3","price":115.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CLH571NB-1.webp?v=1779579964","url":"https:\/\/batteryweb.com\/products\/hasee-g10-cu7pk-replacement-battery-111v-5400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
