It uses OEM part references 55506, 55509, and 56535. If your laptop no longer holds a charge away from the AC adapter, this is the direct replacement cell.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eInspiron 3000 and 3200 platform fit:\u003c\/strong\u003e\n    These models share the same 14.4V battery rail, connector pinout, and BMS handshake protocol — which is why one cell covers the full group. The EEPROM on each replacement cell carries the correct chemistry and capacity data the BIOS reads at boot.\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 3000 chassis through charge, discharge, and re-seat events. The BMS negotiated correctly with the Dell EC controller on each cycle, and the fuel gauge IC tracked cell voltage without dropping into error state.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration cycle:\u003c\/strong\u003e\n    After fitting this cell, 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 a cell swap — skipping it leaves the fuel gauge IC working off the old cell's stored data.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shutting down at 20–30% remaining after battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC is still calibrated to the old, degraded cell. The new cell hits a voltage cliff under combined CPU and display load that the IC hasn't mapped yet. The BIOS reads a voltage drop it associates with empty and triggers shutdown — even though the cell still has real capacity. Run two full discharge-to-hibernate cycles with no interruptions, then charge to 100% each time. After two cycles, the fuel gauge IC re-maps the voltage curve of the new cell and shutdown at 20–30% stops.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reporting battery health as poor immediately after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA fresh cell carries blank or default EEPROM health data, which the Dell BIOS reads as a fault and flags as poor health or unknown state. This is a data mismatch, not a cell fault. The BIOS battery learn cycle rewrites that health register once it completes a full charge-discharge loop. Perform one uninterrupted discharge to hibernate, then charge to 100% — the health warning clears once the EC controller logs a complete cycle against the new cell's voltage profile.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410877218906,"sku":"BWCS-CP3100NB-1","price":80.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43410877251674,"sku":"BWCS-CP3100NB-2","price":94.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43410877284442,"sku":"BWCS-CP3100NB-3","price":105.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CP3100NB-big.webp?v=1779581442","url":"https:\/\/batteryweb.com\/products\/dell-inspiron-3000-replacement-battery-144v-4400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
