It replaces a degraded or dead original cell and restores full mobile operation. Voltage and connector match the original spec — no modifications needed on either model.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eNE511 and NE512 compatibility:\u003c\/strong\u003e\n    Both models use the same 15.2V battery rail, identical connector pinout, and share the same BMS communication protocol. One cell covers both — swapping between models carries no risk of mismatch on voltage or handshake.\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 NE511 hardware. The BMS handshake completed correctly, charge acceptance tracked from 0% through 100% without interruption, and the protection circuit responded normally to end-of-charge termination.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle calibration on the NE511:\u003c\/strong\u003e\n    After installation, run one full discharge until the laptop hibernates, then charge uninterrupted to 100% without use. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the NE511 BIOS flags a new battery as poor health immediately after swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe NE511 BIOS stores battery health data in EEPROM tied to the original cell's charge history. When a new cell is installed, that stored data no longer matches the actual cell — the BIOS reads the mismatch as degradation. Running one full discharge-to-hibernate cycle followed by a complete uninterrupted charge forces the BIOS to rewrite its battery learn data against the new cell. After one or two full cycles, the health indicator returns to normal.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eNE511 shutting down at 20–30% charge shown on the gauge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff issue, not a gauge fault. Under combined CPU and display load, the cell voltage drops faster than the fuel gauge IC can recalibrate — the laptop hits the low-voltage protection threshold while the percentage still reads high. It is most common in the first few cycles after a swap, before the fuel gauge IC has mapped the new cell's discharge curve. Run two or three full discharge-to-hibernate cycles to let the IC recalibrate. After calibration, the shutdown threshold and displayed percentage should align at or below 5%.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409767432282,"sku":"BWCS-ACB115NB-1","price":73.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409767465050,"sku":"BWCS-ACB115NB-2","price":85.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409767497818,"sku":"BWCS-ACB115NB-3","price":94.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ACB115NB-1.webp?v=1779580772","url":"https:\/\/batteryweb.com\/products\/gateway-ne511-replacement-battery-152v-3000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
