It matches the OEM voltage rail and connector pinout for these platforms. Capacity is 6600mAh (73.26Wh) — use the product data figure, not the sticker on the old cell.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGL30 \/ GL31 \/ EL80 \/ EL81 platform fit:\u003c\/strong\u003e\n    These models share a common battery bay dimension (205 × 69 × 20mm), the same 11.1V three-cell voltage rail, and identical BMS communication pins. One cell covers all four platforms 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 and discharge cycles on GL30 and GL31 units. The BMS handshake completed on first connection, charge acceptance started immediately, and the protection circuit tripped correctly at both over-voltage and undervoltage thresholds.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle calibration on the GL30:\u003c\/strong\u003e\n    After fitting, run the laptop on battery until it hibernates at low charge cutoff — do not interrupt. Then charge uninterrupted to 100%. This resets the BIOS battery learn cycle 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 GL30 BIOS flags a new battery as poor health immediately after swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe GL30 BIOS stores battery health data in EEPROM tied to the original cell's charge history. When a new cell connects, the EEPROM data does not match the cell's actual state, so the BIOS reports degraded health before any real measurement occurs. This is a firmware artefact, not a cell defect. Running one full discharge-to-hibernate followed by an uninterrupted charge to 100% forces the fuel gauge IC to re-learn the new cell's capacity curve and clears the false health flag.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eGL30 shutting down at 20–30% charge shown on the OS gauge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC has not yet calibrated against the new cell — the percentage shown is still mapped to the old cell's degraded voltage curve. Under full CPU and display load, the new cell's actual voltage drops faster than the gauge expects, hitting the BMS undervoltage cutoff while the OS still displays 20–30%. The fix is two to three full discharge and charge cycles without interruption. After calibration, the gauge tracks correctly and the early shutdowns stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410816368730,"sku":"BWCS-AUF3HB-1","price":118.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43410816401498,"sku":"BWCS-AUF3HB-2","price":135.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43410816434266,"sku":"BWCS-AUF3HB-3","price":148.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AUF3HB-1.webp?v=1779581181","url":"https:\/\/batteryweb.com\/products\/compal-gl30-replacement-battery-111v-6600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
