It matches the OEM voltage and connector spec for these ultraportable business notebooks. The battery installs directly with no tools and uses the same 9GXD5 part number cross-reference as the original Dell cell.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eE6120 \/ E6220 \/ E6230 \/ E6320 compatibility:\u003c\/strong\u003e\n    These four Latitude models share the same 11.1V battery bay, connector pinout, and BMS communication protocol. The 9GXD5 part number spans all four because Dell used a single battery platform across this E6x20\/E6x30 generation. OEM part numbers 9GXD5, R8R6F, RFJMW, and others in the 312-1239 \/ 451-11703 family all cross to this cell.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell on an E6220 and E6320 chassis. The BMS handshake completed on first boot, the fuel gauge IC registered the cell, and the charge controller cycled through to a full 100% charge without interruption or error flags.\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 battery alone, then charge it uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap on Dell Latitude hardware.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the E6120 BIOS reports \"Battery Not Recommended\" after a new cell is fitted\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eDell's BIOS reads EEPROM data embedded in the battery pack to verify cell identity. When a new cell arrives, that EEPROM data does not match the history the BIOS logged for the old pack, so it flags the battery as unrecognised or not recommended. This is a firmware check, not a fault with the replacement cell. Running one full discharge-to-hibernate followed by an uninterrupted charge to 100% lets the BIOS re-learn the cell and clears the warning on subsequent boots.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down at 20–30% charge shown on new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC has not yet calibrated against the new cell's actual voltage curve. The gauge miscalculates remaining capacity and the laptop hits a voltage cliff under combined CPU and display load before the reported percentage reaches zero. It is not a defective cell. Complete two to three full discharge-and-charge cycles — after the second cycle, check that the BIOS reports a static Wh value near 24Wh and that the OS gauge tracks steadily down to below 10% before the next cutoff.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409762615386,"sku":"BWCS-DE6220NB-1","price":62.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409762648154,"sku":"BWCS-DE6220NB-2","price":73.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409762680922,"sku":"BWCS-DE6220NB-3","price":81.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DE6220NB-1.webp?v=1779580715","url":"https:\/\/batteryweb.com\/products\/dell-latitude-e6120-replacement-battery-111v-2200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
