It replaces OEM parts 06YV0V, 0JJPFK, 1F22N, and XRGXX. If the original cell has degraded or failed, this restores portable operation without replacing the machine.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eG5 and G7 series compatibility:\u003c\/strong\u003e\n    These Dell and Alienware gaming platforms share the same 11.4V three-cell architecture, connector pinout, and BMS handshake protocol — which is why a single part number covers the G5 5590, G7 7590, ALW15M-D1523S, and ALW15M-R2758R among others.\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 a G5 5590 chassis. The BMS negotiated charge termination correctly, the protection circuit tripped at the expected low-voltage threshold, and the BIOS accepted the cell without a firmware block.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBIOS learn cycle after install:\u003c\/strong\u003e\n    After fitting this battery, run the laptop down to hibernate cutoff on one continuous discharge, then charge uninterrupted to 100%. 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 G5 5590 shuts down at 20–30% after a battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Dell G5 5590 runs a combined CPU-plus-display load that pulls hard on the cell at mid-charge states. A new cell that hasn't been through a calibration cycle holds EEPROM data from the factory, not from actual in-system discharge curves. The fuel gauge IC maps capacity against that stale data and triggers shutdown when the cell voltage drops below the threshold it expects — not the real empty point. One full discharge-to-hibernate followed by a full charge corrects the mapping.\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 Dell BIOS reads health status from the battery's EEPROM register, which still reflects the old cell's wear state until a learn cycle writes new data. This is not a fault with the replacement cell — it is a data mismatch. Open Dell SupportAssist or navigate to BIOS battery diagnostics and run a full battery health reset. After one complete charge-to-discharge-to-charge cycle, the register updates and the warning clears. If it persists, confirm the cell voltage at rest reads between 11.1V and 12.6V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409589698650,"sku":"BWCS-DEM171HB-1","price":109.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409589731418,"sku":"BWCS-DEM171HB-2","price":129.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409589764186,"sku":"BWCS-DEM171HB-3","price":143.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DEM171HB-1.webp?v=1779580129","url":"https:\/\/batteryweb.com\/products\/dell-g5-5590-d2785w-replacement-battery-114v-7800mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
