It replaces OEM part numbers including 40011810, 40016133, BP-8X17(P), and BP-Dragon(P\/S). If your original cell no longer holds a charge or the laptop shuts off unexpectedly, this is the direct swap.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEasyNote W-series platform fit:\u003c\/strong\u003e\n    The W1000, W1800, W1801, and W1930 share the same battery bay dimensions, connector pinout, and BMS handshake protocol. All units pull from the same 11.1V three-cell rail, so one cell revision covers the entire W-series line without modification.\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 load cycles on a W1800 unit. The BMS negotiated correctly with the laptop's charge controller, accepted a full charge without cutoff errors, and sustained stable voltage output under combined CPU and display load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on EasyNote W-series:\u003c\/strong\u003e\n    After fitting this cell, run the battery down to hibernate-cutoff — do not force shutdown — then charge uninterrupted to 100%. This single discharge-to-charge cycle resets the BIOS battery learn counter and clears the inaccurate health warning that appears after every cell swap on this platform.\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 immediately after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe EasyNote W-series BIOS reads health data from EEPROM registers written by the original cell during its lifetime. A new cell ships with factory EEPROM values the BIOS doesn't recognise, triggering a false \"poor health\" or \"replace battery\" flag. This is a data mismatch, not a fault with the new cell. Run one full discharge to hibernate-cutoff followed by an uninterrupted charge to 100% — the BIOS battery learn cycle rewrites those registers and clears the warning.\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 actual voltage curve. The gauge still references the old cell's degraded discharge profile, so it miscalculates the remaining capacity and triggers shutdown well before the cell is actually depleted. The fix is completing two to three full discharge-to-charge cycles so the fuel gauge IC maps the new cell correctly. After calibration, the shutoff point drops back to the expected low-voltage threshold near 10.5V under load.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43409815044186,"sku":"BWCS-MD9810NB-1","price":123.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43409815076954,"sku":"BWCS-MD9810NB-2","price":141.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43409815109722,"sku":"BWCS-MD9810NB-3","price":154.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MD9810NB-1.webp?v=1779581043","url":"https:\/\/batteryweb.com\/products\/packard-bell-easynote-w1000-replacement-battery-111v-6600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
