It replaces OEM part numbers BATEL80L6, BATEL80L9, BATFL91L6, and BATFT10L61. The connector, BMS handshake, and cell configuration match the original Dell spec for these three models.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eInspiron 1425 \/ 1427 \/ 1428 platform fit:\u003c\/strong\u003e\n    All three models share the same battery bay dimensions, 11.1V three-cell-series configuration, and BATEL80L6-family OEM part number. The BMS communicates over the same SMBus protocol, so the laptop BIOS recognises this cell without driver changes or firmware patches.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through charge and discharge on an Inspiron 1425 mainboard. The BMS reported state-of-charge correctly after two full cycles, and the BIOS battery health indicator cleared the post-swap warning by the third cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install learn cycle on the Inspiron:\u003c\/strong\u003e\n    After fitting, run the laptop down to hibernate cutoff on battery only — no AC during discharge. Then charge uninterrupted to 100% with the lid open. This single cycle resets the BIOS battery learn routine and stops the \"Consider replacing your battery\" alert that appears after every cell swap on the 1425 platform.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down at 20–30% shown on the Dell Inspiron 1425\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC is still calibrated to the old, degraded cell's voltage curve. The new cell has a steeper voltage drop under combined CPU and display load than the IC currently expects, so it hits a voltage cliff before the gauge reaches zero. The fix is a controlled full discharge to hibernate cutoff — do not force shutdown — followed by a full uninterrupted charge. After two to three of these cycles, the gauge IC re-maps to the new cell's curve and the early shutdowns stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reports wrong Wh rating after replacing the Inspiron 1425 battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Wh figure shown in Dell's BIOS and in Windows Device Manager is read from an EEPROM on the battery's BMS board, not calculated live from the cells. Replacement cells carry EEPROM values that reflect rated chemistry specifications, which can differ by one to three Wh from the original OEM figure. This is a data label difference, not a capacity fault — the cell itself delivers the full 48.84Wh. To confirm actual capacity, run a full discharge cycle and check the Wh drawn in Dell's battery report: open Command Prompt as administrator and run \u003ccode\u003epowercfg \/batteryreport\u003c\/code\u003e.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410820759642,"sku":"BWCS-LVK42NB-1","price":106.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43410820792410,"sku":"BWCS-LVK42NB-2","price":122.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43410820825178,"sku":"BWCS-LVK42NB-3","price":133.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LVK42NB-1.webp?v=1779581257","url":"https:\/\/batteryweb.com\/products\/dell-inspriron-1425-replacement-battery-111v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
