It replaces OEM part numbers including 312-0334, G9817, W5173, and M5701. When the original cell can no longer hold a charge, this unit restores full portable operation.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eInspiron 1000 \/ 1200 \/ 2200 and Latitude 110L compatibility:\u003c\/strong\u003e\n    These four models share the same 14.8V battery rail, identical connector pinout, and the same BMS handshake protocol — so one cell works across all four without modification or adapter.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell on an Inspiron 1200 chassis and confirmed the BMS communicated correctly with the system board, reported accurate state-of-charge data, and accepted a full charge without triggering a fault cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBIOS learn cycle after installation:\u003c\/strong\u003e\n    After fitting this cell, run a full discharge to the hibernate cutoff point, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears on first boot 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\"\u003eBIOS reporting battery health as poor after fitting a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Dell BIOS on these Inspiron and Latitude models reads health data from EEPROM flags written by the original factory cell. When a new cell arrives, those flags don't match what the BIOS expects, so it logs the battery as degraded or unknown — even when the cell is brand new. This is a calibration mismatch, not a fault with the replacement. Running one full discharge-to-hibernate followed by an uninterrupted full charge gives the BIOS controller enough data to rewrite those flags against the new cell's actual chemistry. After one or two cycles, the health status corrects itself.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC hasn't yet calibrated against the new cell's voltage curve. Under full CPU and display load, the cell voltage drops faster than the old calibration curve predicts — the system reads an early voltage cliff and triggers a protective shutdown. The fix is a calibration cycle: let the laptop discharge fully under normal use until it hibernates, then charge straight to 100% without interruption. After two or three of these cycles, the fuel gauge IC maps the correct curve and the shutdowns stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410875842650,"sku":"BWCS-DE1200NB-1","price":81.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43410875875418,"sku":"BWCS-DE1200NB-2","price":95.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43410875908186,"sku":"BWCS-DE1200NB-3","price":106.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DE1200NB-1.webp?v=1779581443","url":"https:\/\/batteryweb.com\/products\/dell-inspiron-1000-replacement-battery-148v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
