It restores portable operation when the factory cell no longer holds a usable charge. Voltage and connector match the original spec for direct installation.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eG2 ENZ K36, GX2 PRO K36, and GX2 compatibility:\u003c\/strong\u003e\n    These three models share the same battery bay dimensions, 14.8V power rail, and BMS handshake protocol — which is why one cell covers all three. The connector pinout and physical footprint (212.70 × 68.35 × 13.50mm) are identical across the range.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through full charge and discharge cycles on a G2 ENZ K36 unit. The BMS communicated correctly with the system board, and charge termination triggered at 16.8V as expected with no error flags.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install discharge cycle:\u003c\/strong\u003e\n    After fitting this battery, run one full discharge to hibernate-cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after swapping cells — skip it and the OS fuel gauge will read incorrectly for weeks.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the G2 ENZ K36 shuts down at 20–30% remaining after a battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC on the system board holds calibration data from the previous cell. When a new cell is installed, that stored data no longer maps accurately to the new chemistry's voltage curve. Under combined CPU and display load, the laptop hits a voltage point the old calibration marks as \"empty\" — even though actual capacity remains. The fix is two to three full discharge-to-hibernate and full-charge cycles, which forces the fuel gauge IC to relearn the new cell's curve.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reporting battery health as \"poor\" or \"unknown\" immediately after install\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe BIOS reads health status from EEPROM data embedded in the battery's BMS chip. A new cell ships with factory EEPROM values that don't yet match the laptop's learned charge history, so the BIOS flags it as degraded or unrecognised. This is not a fault with the cell. Run the battery learn cycle — one full discharge to hibernate-cutoff followed by an uninterrupted charge to 100% — and recheck BIOS health status after the cycle completes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409542774874,"sku":"BWCS-ARG200NB-1","price":83.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409542807642,"sku":"BWCS-ARG200NB-2","price":99.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409542840410,"sku":"BWCS-ARG200NB-3","price":110.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ARG200NB-1.webp?v=1779579964","url":"https:\/\/batteryweb.com\/products\/gxnova-g2-enz-k36-replacement-battery-148v-4000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
