It slots into the same bay as the factory pack and connects to the same charging circuit. Cross-reference OEM part numbers BATEL80L6, CBPIL44, GC020009Y00, GC020009Z00, GC02000AM00, and ID6 to confirm fitment before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEL80 and EL81 shared platform:\u003c\/strong\u003e\n    Both models run the same 11.1V three-cell series configuration and use an identical connector and BMS handshake protocol. A single cell covers both SKUs without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on an EL80 chassis. The BMS communicated cleanly with the laptop's charge controller, and charge current tapered correctly at full capacity without triggering a fault state.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle conditioning on the EL80:\u003c\/strong\u003e\n    After fitting, run the laptop on battery until it hibernates at cutoff — do not interrupt it. Then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after a 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 battery health as poor immediately after fitting a new cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe EL80's BIOS stores capacity and health data in EEPROM tied to the original cell. When a new cell goes in, that stored data no longer matches actual charge state, so the BIOS flags the battery as poor or unknown. This is not a fault with the replacement cell. Run one complete discharge-to-hibernate then a full uninterrupted charge. After two to three cycles, the fuel gauge IC recalibrates and the health status clears.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the cell cannot hold voltage under combined CPU and display load — the pack hits a voltage cliff before the fuel gauge reads zero. The BIOS sees the actual cell voltage drop below its cutoff threshold and forces shutdown regardless of the percentage displayed. The fuel gauge IC is reading a calibration curve that no longer maps accurately to the new cell. Run two full discharge and charge cycles back to back, and the gauge will re-anchor its curve — shutdowns should stop well before 20%.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410852479066,"sku":"BWCS-AUF3NB-1","price":73.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43410852511834,"sku":"BWCS-AUF3NB-2","price":86.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43410852544602,"sku":"BWCS-AUF3NB-3","price":95.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AUF3NB-1.webp?v=1779581357","url":"https:\/\/batteryweb.com\/products\/mitac-el80-replacement-battery-111v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
