It slots into the standard battery bay and connects via the original locking latch. Capacity is 6600mAh (73.26Wh), matching the OEM specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eiGo 5000, 5461, and 5562 fitment:\u003c\/strong\u003e\n    These three models share the same 11.1V battery rail, physical connector pinout, and BMS handshake protocol — one cell covers all three. The OEM part numbers 442671700002, 442671600002, 442671700003, and CGR-B\/T19SE-MSL all cross-reference to this specification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on the iGo 5000 platform. The BMS negotiated correctly with the laptop EC on the first connection — no false fault flags during charging or under combined CPU and display load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle calibration after install:\u003c\/strong\u003e\n    After fitting, run the battery down 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 after every cell swap. Skip this step and the fuel gauge IC starts the next cycle with stale reference data.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reporting poor battery health immediately after fitting a new cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe iGo series stores charge history and cell health data in EEPROM on the battery itself. When you swap cells, the BIOS reads the blank or mismatched EEPROM data on the new pack and flags it as degraded. This is not a fault with the replacement cell — it is stale reference data. Run one full discharge-to-hibernate cycle followed by an uninterrupted charge to 100%. After two to three cycles the BIOS recalibrates and the health warning clears.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shutting down at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff issue, not a capacity fault. Under combined CPU and display load, the cell voltage drops faster than the fuel gauge IC predicts — the system hits the low-voltage cutoff threshold while the OS still shows charge remaining. The fuel gauge IC is calibrated against the old cell's discharge curve, not the new one. Run two full discharge-to-hibernate cycles so the IC rebuilds its internal model against the actual cell — the shutdown point should stabilise above 5% after recalibration.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410829738074,"sku":"BWCS-MT8575NB-1","price":70.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43410829770842,"sku":"BWCS-MT8575NB-2","price":82.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43410829803610,"sku":"BWCS-MT8575NB-3","price":92.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MT8575NB-big.webp?v=1779581286","url":"https:\/\/batteryweb.com\/products\/packard-bell-igo-5000-replacement-battery-111v-6600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
