It replaces a degraded or failed original cell and restores portable operation to the machine. Capacity is rated at 73.26Wh, matching the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eE500 platform compatibility:\u003c\/strong\u003e\n    The E500 shares its battery bay dimensions and connector pinout across several LG notebook variants. Cross-reference OEM part numbers — including SQU-503, A32-F3, and BATEL80L6 — to confirm the right fit before installation. This battery covers that full group.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through a full charge and discharge cycle on E500-class hardware. The BMS communicated correctly with the system, charge acceptance was normal, and the fuel gauge IC registered cell voltage without error.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration cycle:\u003c\/strong\u003e\n    After fitting this battery, run the laptop on battery power until it hibernates at cutoff — do not interrupt. Then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that typically appears after any 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\"\u003eBIOS reporting poor battery health immediately after replacement\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe E500 BIOS reads health data from EEPROM stored on the battery's BMS board. When a new cell goes in, the BIOS compares accumulated cycle data — which is blank — against its internal thresholds and flags it as unknown or degraded. This is not a fault with the replacement cell. Running one full discharge-to-hibernate followed by an uninterrupted charge to 100% allows the fuel gauge IC to write calibrated data back to the BIOS. After two to three cycles the health status updates and the warning clears.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down at 20–30% shown on the fuel gauge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff issue, not a fuel gauge miscalibration. Under combined CPU and display load, cell voltage drops faster than the fuel gauge IC can track, and the BMS cuts power before the displayed percentage reaches zero. It appears most often in the first few cycles when the fuel gauge has not yet mapped the new cell's discharge curve. Run two full discharge-to-hibernate cycles with the display at full brightness and a CPU load running to force the IC to recalibrate its low-voltage cutoff model. After calibration the shutdown threshold should stabilise at or below 5% displayed.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410817056858,"sku":"BWCS-AUF3HB-1","price":118.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43410817089626,"sku":"BWCS-AUF3HB-2","price":135.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43410817122394,"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\/lg-e500-replacement-battery-111v-6600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
