It replaces OEM part numbers DR202, EMC36, ME202BB, NL2020, and SMP02. If your original cell no longer holds a charge or fails to register in the OS, this cell restores portable power to the laptop.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e7550 and 7750 shared platform:\u003c\/strong\u003e\n    Both models run the same 10.8V battery rail with an identical connector and BMS handshake protocol. One cell covers both — no hardware modification needed.\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 7550 platform. The BMS accepted charge from zero without triggering a reject flag, and the fuel gauge IC registered the cell correctly after two full cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle recalibration on the 7550:\u003c\/strong\u003e\n    After installing, run one full discharge to the hibernate cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap on these Daewoo notebooks.\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 after installing a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Daewoo 7550 BIOS reads health data stored in the old cell's EEPROM. When a new cell installs, the BIOS compares its logged wear data against the fresh cell and flags a mismatch as poor health. This is a firmware calibration issue, not a fault with the replacement. Run one complete discharge to hibernate, then a full uninterrupted charge to 100% — the BIOS learn cycle re-anchors to the new cell's actual capacity after this sequence.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down while the OS still shows 20–30% remaining\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC has not yet calibrated against the new cell's voltage curve. The IC is still using the old cell's discharge profile, so it misreads remaining capacity under full CPU and display load. At high draw, the cell voltage drops faster than the stale profile predicts, and the BMS cuts power before the displayed percentage reaches zero. Complete two to three full discharge-charge cycles and the gauge IC will track the actual voltage cliff — the shutdowns stop once it reads below 3.0V per cell correctly.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410838814810,"sku":"BWCS-SP500HB-1","price":88.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43410838847578,"sku":"BWCS-SP500HB-2","price":103.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43410838880346,"sku":"BWCS-SP500HB-3","price":114.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SP500HB-1.webp?v=1779581321","url":"https:\/\/batteryweb.com\/products\/daewoo-7550-replacement-battery-108v-6600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
